text: Melt from supraglacial ice cliffs is an important contributor to the mass
loss of debris-covered glaciers. However, ice cliff contribution is difficult
to quantify as they are highly dynamic features, and the paucity of observations
of melt rates and their variability leads to large modelling uncertainties. We
quantify monsoon season melt and 3D evolution of four ice cliffs over two debris-covered
glaciers in High Mountain Asia (Langtang Glacier, Nepal, and 24K Glacier, China)
at very high resolution using terrestrial photogrammetry applied to imagery captured
from time-lapse cameras installed on lateral moraines. We derive weekly flow-corrected
digital elevation models (DEMs) of the glacier surface with a maximum vertical
bias of ±0.2 m for Langtang Glacier and ±0.05 m for 24K Glacier and use change
detection to determine distributed melt rates at the surfaces of the ice cliffs
throughout the study period. We compare the measured melt patterns with those
derived from a 3D energy balance model to derive the contribution of the main
energy fluxes. We find that ice cliff melt varies considerably throughout the
melt season, with maximum melt rates of 5 to 8 cm d−1, and their average melt
rates are 11–14 (Langtang) and 4.5 (24K) times higher than the surrounding debris-covered
ice. Our results highlight the influence of redistributed supraglacial debris
on cliff melt. At both sites, ice cliff albedo is influenced by the presence of
thin debris at the ice cliff surface, which is largely controlled on 24K Glacier
by liquid precipitation events that wash away this debris. Slightly thicker or
patchy debris reduces melt by 1–3 cm d−1 at all sites. Ultimately, our observations
show a strong spatio-temporal variability in cliff area at each site, which is
controlled by supraglacial streams and ponds and englacial cavities that promote
debris slope destabilisation and the lateral expansion of the cliffs. These findings
highlight the need to better represent processes of debris redistribution in ice
cliff models, to in turn improve estimates of ice cliff contribution to glacier
melt and the long-term geomorphological evolution of debris-covered glacier surfaces.

text: "Currently, about 12 %–13 % of High Mountain Asia’s glacier area is debris-covered,
which alters its surface mass balance. However, in regional-scale modelling approaches,
debris-covered glaciers are typically treated as clean-ice glaciers, leading to
a bias when modelling their future evolution. Here, we present a new approach
for modelling debris area and thickness evolution, applicable from single glaciers
to the global scale. We derive a parameterization and implement it as a module
into the Global Glacier Evolution Model (GloGEMflow), a combined mass-balance
ice-flow model. The module is initialized with both glacier-specific observations
of the debris' spatial distribution and estimates of debris thickness. These data
sets account for the fact that debris can either enhance or reduce surface melt
depending on thickness. Our model approach also enables representing the spatiotemporal
evolution of debris extent and thickness. We calibrate and evaluate the module
on a selected subset of glaciers and apply GloGEMflow using different climate
scenarios to project the future evolution of all glaciers in High Mountain Asia
until 2100. Explicitly accounting for debris cover has only a minor effect on
the projected mass loss, which is in line with previous projections. Despite this
small effect, we argue that the improved process representation is of added value
when aiming at capturing intra-glacier scales, i.e. spatial mass-balance distribution.\r\nDepending
on the climate scenario, the mean debris-cover fraction is expected to increase,
while mean debris thickness is projected to show only minor changes, although
large local thickening is expected. To isolate the influence of explicitly accounting
for supraglacial debris cover, we re-compute glacier evolution without the debris-cover
module. We show that glacier geometry, area, volume, and flow velocity evolve
differently, especially at the level of individual glaciers. This highlights the
importance of accounting for debris cover and its spatiotemporal evolution when
projecting future glacier changes."

text: "The Indian and East Asian summer monsoons shape the melt and accumulation
patterns of glaciers in High Mountain Asia in complex ways due to the interaction
of persistent cloud cover, large temperature ranges, high atmospheric water content
and high precipitation rates. Glacier energy- and mass-balance modelling using
in situ measurements offers insights into the ways in which surface processes
are shaped by climatic regimes. In this study, we use a full energy- and mass-balance
model and seven on-glacier automatic weather station datasets from different parts
of the Central and Eastern Himalaya to investigate how monsoon conditions influence
the glacier surface energy and mass balance. In particular, we look at how debris-covered
and debris-free glaciers respond differently to monsoonal conditions.\r\nThe radiation
budget primarily controls the melt of clean-ice glaciers, but turbulent fluxes
play an important role in modulating the melt energy on debris-covered glaciers.
The sensible heat flux decreases during core monsoon, but the latent heat flux
cools the surface due to evaporation of liquid water. This interplay of radiative
and turbulent fluxes causes debris-covered glacier melt rates to stay almost constant
through the different phases of the monsoon. Ice melt under thin debris, on the
other hand, is amplified by both the dark surface and the turbulent fluxes, which
intensify melt during monsoon through surface heating and condensation.\r\nPre-monsoon
snow cover can considerably delay melt onset and have a strong impact on the seasonal
mass balance. Intermittent monsoon snow cover lowers the melt rates at high elevation.
This work is fundamental to the understanding of the present and future Himalayan
cryosphere and water budget, while informing and motivating further glacier- and
catchment-scale research using process-based models."

text: Near-surface air temperature (Ta) is highly important for modelling glacier
ablation, though its spatio-temporal variability over melting glaciers still remains
largely unknown. We present a new dataset of distributed Ta for three glaciers
of different size in the south-east Tibetan Plateau during two monsoon-dominated
summer seasons. We compare on-glacier Ta to ambient Ta extrapolated from several
local off-glacier stations. We parameterise the along-flowline sensitivity of
Ta on these glaciers to changes in off-glacier temperatures (referred to as “temperature
sensitivity”) and present the results in the context of available distributed
on-glacier datasets around the world. Temperature sensitivity decreases rapidly
up to 2000–3000 m along the down-glacier flowline distance. Beyond this distance,
both the Ta on the Tibetan glaciers and global glacier datasets show little additional
cooling relative to the off-glacier temperature. In general, Ta on small glaciers
(with flowline distances <1000 m) is highly sensitive to temperature changes outside
the glacier boundary layer. The climatology of a given region can influence the
general magnitude of this temperature sensitivity, though no strong relationships
are found between along-flowline temperature sensitivity and mean summer temperatures
or precipitation. The terminus of some glaciers is affected by other warm-air
processes that increase temperature sensitivity (such as divergent boundary layer
flow, warm up-valley winds or debris/valley heating effects) which are evident
only beyond ∼70 % of the total glacier flowline distance. Our results therefore
suggest a strong role of local effects in modulating temperature sensitivity close
to the glacier terminus, although further work is still required to explain the
variability of these effects for different glaciers.

text: Information about end-of-winter spatial distribution of snow depth is important
for seasonal forecasts of spring/summer streamflow in high-mountain regions. Nevertheless,
such information typically relies upon extrapolation from a sparse network of
observations at low elevations. Here, we test the potential of high-resolution
snow depth data derived from optical stereophotogrammetry of Pléiades satellites
for improving the representation of snow depth initial conditions (SDICs) in a
glacio-hydrological model and assess potential improvements in the skill of snowmelt
and streamflow simulations in a high-elevation Andean catchment. We calibrate
model parameters controlling glacier mass balance and snow cover evolution using
ground-based and satellite observations, and consider the relative importance
of accurate estimates of SDICs compared to model parameters and forcings. We find
that Pléiades SDICs improve the simulation of snow-covered area, glacier mass
balance, and monthly streamflow compared to alternative SDICs based upon extrapolation
of meteorological variables or statistical methods to estimate SDICs based upon
topography. Model simulations are found to be sensitive to SDICs in the early
spring (up to 48% variability in modeled streamflow compared to the best estimate
model), and to temperature gradients in all months that control albedo and melt
rates over a large elevation range (>2,400 m). As such, appropriately characterizing
the distribution of total snow volume with elevation is important for reproducing
total streamflow and the proportions of snowmelt. Therefore, optical stereo-photogrammetry
offers an advantage for obtaining SDICs that aid both the timing and magnitude
of streamflow simulations, process representation (e.g., snow cover evolution)
and has the potential for large spatial domains.

text: As glaciers adjust their size in response to climate variations, long-term
changes in meltwater production can be expected, affecting the local availability
of water resources. We investigate glacier runoff in the period 1955–2016 in the
Maipo River basin (4843 km2, 33.0–34.3∘ S, 69.8–70.5∘ W), in the semiarid Andes
of Chile. The basin contains more than 800 glaciers, which cover 378 km2 in total
(inventoried in 2000). We model the mass balance and runoff contribution of 26
glaciers with the physically oriented and fully distributed TOPKAPI (Topographic
Kinematic Approximation and Integration)-ETH glacio-hydrological model and extrapolate
the results to the entire basin. TOPKAPI-ETH is run at a daily time step using
several glaciological and meteorological datasets, and its results are evaluated
against streamflow records, remotely sensed snow cover, and geodetic mass balances
for the periods 1955–2000 and 2000–2013. Results show that in 1955–2016 glacier
mass balance had a general decreasing trend as a basin average but also had differences
between the main sub-catchments. Glacier volume decreased by one-fifth (from 18.6±4.5
to 14.9±2.9 km3). Runoff from the initially glacierized areas was 177±25 mm yr−1
(16±7 % of the total contributions to the basin), but it shows a decreasing sequence
of maxima, which can be linked to the interplay between a decrease in precipitation
since the 1980s and the reduction of ice melt. Glaciers in the Maipo River basin
will continue retreating because they are not in equilibrium with the current
climate. In a hypothetical constant climate scenario, glacier volume would reduce
to 81±38 % of the year 2000 volume, and glacier runoff would be 78±30 % of the
1955–2016 average. This would considerably decrease the drought mitigation capacity
of the basin.

text: Obtaining detailed information about high mountain snowpacks is often limited
by insufficient ground-based observations and uncertainty in the (re)distribution
of solid precipitation. We utilize high-resolution optical images from Pléiades
satellites to generate a snow depth map, at a spatial resolution of 4 m, for a
high mountain catchment of central Chile. Results are negatively biased (median
difference of −0.22 m) when compared against observations from a terrestrial Light
Detection And Ranging scan, though replicate general snow depth variability well.
Additionally, the Pléiades dataset is subject to data gaps (17% of total pixels),
negative values for shallow snow (12%), and noise on slopes >40–50° (2%). We correct
and filter the Pléiades snow depths using surface classification techniques of
snow-free areas and a random forest model for data gap filling. Snow depths (with
an estimated error of ~0.36 m) average 1.66 m and relate well to topographical
parameters such as elevation and northness in a similar way to previous studies.
However, estimations of snow depth based upon topography (TOPO) or physically
based modeling (DBSM) cannot resolve localized processes (i.e., avalanching or
wind scouring) that are detected by Pléiades, even when forced with locally calibrated
data. Comparing these alternative model approaches to corrected Pléiades snow
depths reveals total snow volume differences between −28% (DBSM) and +54% (TOPO)
for the catchment and large differences across most elevation bands. Pléiades
represents an important contribution to understanding snow accumulation at sparsely
monitored catchments, though ideally requires a careful systematic validation
procedure to identify catchment-scale biases and errors in the snow depth derivation.

text: The snow cover dynamics of High Mountain Asia are usually assessed at spatial
resolutions of 250 m or greater, but this scale is too coarse to clearly represent
the rugged topography common to the region. Higher-resolution measurement of snow-covered
area often results in biased sampling due to cloud cover and deep shadows. We
therefore develop a Normalized Difference Snow Index-based workflow to delineate
snow lines from Landsat Thematic Mapper/Enhanced Thematic Mapper+ imagery and
apply it to the upper Langtang Valley in Nepal, processing 194 scenes spanning
1999 to 2013. For each scene, we determine the spatial distribution of snow line
altitudes (SLAs) with respect to aspect and across six subcatchments. Our results
show that the mean SLA exhibits distinct seasonal behavior based on aspect and
subcatchment position. We find that SLA dynamics respond to spatial and seasonal
trade-offs in precipitation, temperature, and solar radiation, which act as primary
controls. We identify two SLA spatial gradients, which we attribute to the effect
of spatially variable precipitation. Our results also reveal that aspect-related
SLA differences vary seasonally and are influenced by solar radiation. In terms
of seasonal dominant controls, we demonstrate that the snow line is controlled
by snow precipitation in winter, melt in premonsoon, a combination of both in
postmonsoon, and temperature in monsoon, explaining to a large extent the spatial
and seasonal variability of the SLA in the upper Langtang Valley. We conclude
that while SLA and snow-covered area are complementary metrics, the SLA has a
strong potential for understanding local-scale snow cover dynamics and their controlling
mechanisms.

text: We present a field-data rich modelling analysis to reconstruct the climatic
forcing, glacier response, and runoff generation from a high-elevation catchment
in central Chile over the period 2000–2015 to provide insights into the differing
contributions of debris-covered and debris-free glaciers under current and future
changing climatic conditions. Model simulations with the physically based glacio-hydrological
model TOPKAPI-ETH reveal a period of neutral or slightly positive mass balance
between 2000 and 2010, followed by a transition to increasingly large annual mass
losses, associated with a recent mega drought. Mass losses commence earlier, and
are more severe, for a heavily debris-covered glacier, most likely due to its
strong dependence on snow avalanche accumulation, which has declined in recent
years. Catchment runoff shows a marked decreasing trend over the study period,
but with high interannual variability directly linked to winter snow accumulation,
and high contribution from ice melt in dry periods and drought conditions. The
study demonstrates the importance of incorporating local-scale processes such
as snow avalanche accumulation and spatially variable debris thickness, in understanding
the responses of different glacier types to climate change. We highlight the increased
dependency of runoff from high Andean catchments on the diminishing resource of
glacier ice during dry years.

text: Snow depth patterns over glaciers are controlled by precipitation, snow redistribution
due to wind and avalanches, and the exchange of energy with the atmosphere that
determines snow ablation. While many studies have advanced the understanding of
ablation processes, less is known about winter snow patterns and their variability
over glaciers. We analyze snow depth on Haut Glacier d'Arolla, Switzerland, in
the two winter seasons 2006–2007 and 2010–2011 to (1) understand whether snow
depth over an alpine glacier at the end of the accumulation season exhibits a
behavior similar to the one observed on single slopes and vegetated areas; and
(2) investigate the snow pattern consistency over the two accumulation seasons.
We perform this analysis on a data set of high-resolution lidar-derived snow depth
using variograms and fractal parameters. Our first main result is that snow depth
patterns on the glacier exhibit a multiscale behavior, with a scale break around
20 m after which the fractal dimension increases, indicating more autocorrelated
structure before the scale break than after. Second, this behavior is consistent
over the two years, with fractal parameters and their spatial variability almost
constant in the two seasons. We also show that snow depth patterns exhibit a distinct
behavior in the glacier tongue and the upper catchment, with longer correlation

distinctions that are likely induced by different processes and that should be
taken into account when extrapolating snow depth from limited samples.

text: Ice cliffs within a supraglacial debris cover have been identified as a source
for high ablation relative to the surrounding debris-covered area. Due to their
small relative size and steep orientation, ice cliffs are difficult to detect
using nadir-looking space borne sensors. The method presented here uses surface
slopes calculated from digital elevation model (DEM) data to map ice cliff geometry
and produce an ice cliff probability map. Surface slope thresholds, which can
be sensitive to geographic location and/or data quality, are selected automatically.
The method also attempts to include area at the (often narrowing) ends of ice
cliffs which could otherwise be neglected due to signal saturation in surface
slope data. The method was calibrated in the eastern Alaska Range, Alaska, USA,
against a control ice cliff dataset derived from high-resolution visible and thermal
data. Using the same input parameter set that performed best in Alaska, the method
was tested against ice cliffs manually mapped in the Khumbu Himal, Nepal. Our
results suggest the method can accommodate different glaciological settings and
different DEM data sources without a data intensive (high-resolution, multi-data
source) recalibration.

text: 'We investigate the energy balance and ablation regimes of glaciers in high-elevation,
dry environments using glaciometeorological data collected on six glaciers in
the semiarid Andes of North-Central Chile (29–34°S, 3127–5324 m). We use a point-scale
physically based energy balance (EB) model and an enhanced Temperature-Index (ETI)
model that calculates melt rates only as a function of air temperature and net
shortwave radiation. At all sites, the largest energy inputs are net shortwave
and incoming longwave radiation, which are controlled by surface albedo and elevation,
respectively. Turbulent fluxes cancel each other out at the lower sites, but as
elevation increases, cold, dry and wind-exposed conditions increase the magnitude
of negative latent heat fluxes, associated with large surface sublimation rates.
In midsummer (January), ablation rates vary from 67.9 mm w.e. d−1 at the lowest
site (∼100% corresponding to melt), to 2.3 mm w.e. d−1 at the highest site (>85%
corresponding to surface sublimation). At low-elevation, low-albedo, melt-dominated
sites, the ETI model correctly reproduces melt using a large range of possible
parameters, but both the performance and parameter transferability decrease with
elevation for two main reasons: (i) the air temperature threshold approach for
melt onset does not capture the diurnal variability of melt in cold and strong
irradiated environments and (ii) energy losses decrease the correlation between
melt and net shortwave radiation. We summarize our results by means of an elevation
profile of ablation components that can be used as reference in future studies
of glacier ablation in the semiarid Andes.'

text: 'We apply the process-based, distributed TOPKAPI-ETH glacio-hydrological model
to a glacierized catchment (19% glacierized) in the semiarid Andes of central
Chile. The semiarid Andes provides vital freshwater resources to valleys in Chile
and Argentina, but only few glacio-hydrological modelling studies have been conducted,
and its dominant hydrological processes remain poorly understood. The catchment
contains two debris-free glaciers reaching down to 3900 m asl (Bello and Yeso
glaciers) and one debris-covered avalanche-fed glacier reaching to 3200 m asl
(Piramide Glacier). Our main objective is to compare the mass balance and runoff
contributions of both glacier types under current climatic conditions. We use
a unique dataset of field measurements collected over two ablation seasons combined
with the distributed TOPKAPI-ETH model that includes physically oriented parameterizations
of snow and ice ablation, gravitational distribution of snow, snow albedo evolution
and the ablation of debris-covered ice. Model outputs indicate that while the
mass balance of Bello and Yeso glaciers is mostly explained by temperature gradients,
the Piramide Glacier mass balance is governed by debris thickness and avalanches
and has a clear non-linear profile with elevation as a result. Despite the thermal
insulation effect of the debris cover, the mass balance and contribution to runoff
from debris-free and debris-covered glaciers are similar in magnitude, mainly
because of elevation differences. However, runoff contributions are distinct in
time and seasonality with ice melt starting approximately four weeks earlier from
the debris-covered glacier, what is of relevance for water resources management.
At the catchment scale, snowmelt is the dominant contributor to runoff during
both years. However, during the driest year of our simulations, ice melt contributes
42 ± 8% and 67 ± 6% of the annual and summer runoff, respectively. Sensitivity
analyses show that runoff is most sensitive to temperature and precipitation gradients,
melt factors and debris cover thickness. '

text: This paper presents a methodology for hydrograph separation in mountain watersheds,
which aims at identifying flow sources among ungauged headwater sub-catchments
through a combination of observed streamflow and data on natural tracers including
isotope and dissolved solids. Daily summer and bi-daily spring season water samples
obtained at the outlet of the Juncal River Basin in the Andes of Central Chile
were analysed for all major ions as well as stable water isotopes, δ18O and δD.
Additionally, various samples from rain, snow, surface streams and exfiltrating
subsurface water (springs) were sampled throughout the catchment. A principal
component analysis was performed in order to address cross-correlation in the
tracer dataset, reduce the dimensionality of the problem and uncover patterns
of variability. Potential sources were identified in a two-component U-space that
explains 94% of the observed tracer variability at the catchment outlet. Hydrograph
separation was performed through an Informative-Bayesian model. Our results indicate
that the Juncal Norte Glacier headwater sub-catchment contributed at least 50%
of summer flows at the Juncal River Basin outlet during the 2011–2012 water year
(a hydrologically dry period in the Region), even though it accounts for only
27% of the basin area. Our study confirms the value of combining solute and isotope
information for estimating source contributions in complex hydrologic systems,
and provides insights regarding experimental design in high-elevation semi-arid
catchments. The findings of this study can be useful for evaluating modelling
studies of the hydrological consequences of the rapid decrease in glacier cover
observed in this region, by providing insights into the origin of river water
in basins with little hydrometeorological information.

text: This study presents volume and mass changes of seven (five partially debris-covered,
two debris-free) glaciers in the upper Langtang catchment in Nepal. We use a digital
elevation model (DEM) from 1974 stereo Hexagon satellite data and seven DEMs derived
from 2006–2015 stereo or tri-stereo satellite imagery (e.g., SPOT6/7). The availability
of multiple independent DEM differences allows the identification of a robust
signal and narrowing down of the uncertainty about recent volume changes. The
volume changes calculated over several multiyear periods between 2006 and 2015
consistently indicate that glacier thinning has accelerated with respect to the
period 1974–2006. We calculate an ensemble-mean elevation change rate of –0.45 ± 0.18 m a−1
for 2006–2015, while for the period 1974–2006 we compute a rate of −0.24 ± 0.08 m a−1.
However, the behavior of glaciers in the study area is heterogeneous, and the
presence or absence of debris does not seem to be a good predictor for mass balance
trends. Debris-covered tongues have nonlinear thinning profiles, and we show that
recent accelerations in thinning correlate with the presence of supraglacial cliffs
and lakes. At stagnating glacier areas near the glacier front, however, thinning
rates decreased with time or remained constant. The April 2015 Nepal earthquake
triggered large avalanches in the study catchment. Analysis of two post-earthquake
DEMs revealed that the avalanche deposit volumes remaining 6 months after the
earthquake are negligible in comparison to 2006–2015 elevation changes. However,
the deposits compensate about 40 % the mass loss of debris-covered tongues of
1 average year.

text: "Debris-covered glaciers are increasingly studied because it is assumed that
debris cover extent and thickness could increase in a warming climate, with more
regular rockfalls from the surrounding slopes and more englacial melt-out material.
Debris energy-balance models have been developed to account for the melt rate
enhancement/reduction due to a thin/thick debris layer, respectively. However,
such models require a large amount of input data that are not often available,
especially in remote mountain areas such as the Himalaya, and can be difficult
to extrapolate. Due to their lower data requirements, empirical models have been
used extensively in clean glacier melt modelling. For debris-covered glaciers,
however, they generally simplify the debris effect by using a single melt-reduction
factor which does not account for the influence of varying debris thickness on
melt and prescribe a constant reduction for the entire melt across a glacier.\r\n\r\nIn
this paper, we present a new temperature-index model that accounts for debris
thickness in the computation of melt rates at the debris-ice interface. The model
empirical parameters are optimized at the point scale for varying debris thicknesses
against melt rates simulated by a physically-based debris energy balance model.
The latter is validated against ablation stake readings and surface temperature
measurements. Each parameter is then related to a plausible set of debris thickness
values to provide a general and transferable parameterization. We develop the
model on Miage Glacier, Italy, and then test its transferability on Haut Glacier
d’Arolla, Switzerland.\r\n\r\nThe performance of the new debris temperature-index
(DETI) model in simulating the glacier melt rate at the point scale is comparable
to the one of the physically based approach, and the definition of model parameters
as a function of debris thickness allows the simulation of the nonlinear relationship
of melt rate to debris thickness, summarised by the Østrem curve. Its large number
of parameters might be a limitation, but we show that the model is transferable
in time and space to a second glacier with little loss of performance. We thus
suggest that the new DETI model can be included in continuous mass balance models
of debris-covered glaciers, because of its limited data requirements. As such,
we expect its application to lead to an improvement in simulations of the debris-covered
glacier response to climate in comparison with models that simply recalibrate
empirical parameters to prescribe a constant across glacier reduction in melt."

text: Meteorological studies in high-mountain environments form the basis of our
understanding of catchment hydrology and glacier accumulation and melt processes,
yet high-altitude (>4000 m above sea level, asl) observatories are rare. This
research presents meteorological data recorded between December 2012 and November
2013 at seven stations in Nepal, ranging in elevation from 3860 to 5360 m asl.
Seasonal and diurnal cycles in air temperature, vapour pressure, incoming short-wave
and long-wave radiation, atmospheric transmissivity, wind speed, and precipitation
are compared between sites. Solar radiation strongly affects diurnal temperature
and vapour pressure cycles, but local topography and valley-scale circulations
alter wind speed and precipitation cycles. The observed diurnal variability in
vertical temperature gradients in all seasons highlights the importance of in
situ measurements for melt modelling. The monsoon signal (progressive onset and
sharp end) is visible in all data-sets, and the passage of the remnants of Typhoon
Phailin in mid-October 2013 provides an interesting case study on the possible
effects of such storms on glaciers in the region.

text: "The hydrology of high-elevation watersheds of the Hindu Kush-Himalaya region
(HKH) is poorly known. The correct representation of internal states and process
dynamics in glacio-hydrological models can often not be verified due to missing
in situ measurements. We use a new set of detailed ground data from the upper
Langtang valley in Nepal to systematically guide a state-of-the art glacio-hydrological
model through a parameter assigning process with the aim to understand the hydrology
of the catchment and contribution of snow and ice processes to runoff. 14 parameters
are directly calculated on the basis of local data, and 13 parameters are calibrated
against 5 different datasets of in situ or remote sensing data. Spatial fields
of debris thickness are reconstructed through a novel approach that employs data
from an Unmanned Aerial Vehicle (UAV), energy balance modeling and statistical
techniques. The model is validated against measured catchment runoff (Nash–Sutcliffe
efficiency 0.87) and modeled snow cover is compared to Landsat snow cover. The
advanced representation of processes allowed assessing the role played by avalanching
for runoff for the first time for a Himalayan catchment (5% of annual water inputs
to the hydrological system are due to snow redistribution) and to quantify the
hydrological significance of sub-debris ice melt (9% of annual water inputs).
Snowmelt is the most important contributor to total runoff during the hydrological
year 2012/2013 (representing 40% of all sources), followed by rainfall (34%) and
ice melt (26%). A sensitivity analysis is used to assess the efficiency of the
monitoring network and identify the timing and location of field measurements
that constrain model uncertainty. The methodology to set up a glacio-hydrological
model in high-elevation regions presented in this study can be regarded as a benchmark
for modelers in the HKH seeking to evaluate their calibration approach, their
experimental setup and thus to reduce the predictive model uncertainty.\r\n\r\n"

text: The performance of glaciohydrological models which simulate catchment response
to climate variability depends to a large degree on the data used to force the
models. The forcing data become increasingly important in high-elevation, glacierized
catchments where the interplay between extreme topography, climate, and the cryosphere
is complex. It is challenging to generate a reliable forcing data set that captures
this spatial heterogeneity. In this paper, we analyze the results of a 1 year
field campaign focusing on air temperature and precipitation observations in the
Langtang valley in the Nepalese Himalayas. We use the observed time series to
characterize both temperature lapse rates (LRs) and precipitation gradients (PGs).
We study their spatial and temporal variability, and we attempt to identify possible
controlling factors. We show that very clear LRs exist in the valley and that
there are strong seasonal differences related to the water vapor content in the
atmosphere. Results also show that the LRs are generally shallower than the commonly
used environmental lapse rates. The analysis of the precipitation observations
reveals that there is great variability in precipitation over short horizontal
distances. A uniform valley wide PG cannot be established, and several scale-dependent
mechanisms may explain our observations. We complete our analysis by showing the
impact of the observed LRs and PGs on the outputs of the TOPKAPI-ETH glaciohydrological
model. We conclude that LRs and PGs have a very large impact on the water balance
composition and that short-term monitoring campaigns have the potential to improve
model quality considerably.

text: We use two hydrological models of varying complexity to study the Juncal River
Basin in the Central Andes of Chile with the aim to understand the degree of conceptualization
and the spatial structure that are needed to model present and future streamflows.
We use a conceptual semi-distributed model based on elevation bands [Water Evaluation
and Planning (WEAP)], frequently used for water management, and a physically oriented,
fully distributed model [Topographic Kinematic Wave Approximation and Integration
ETH Zurich (TOPKAPI-ETH)] developed for research purposes mainly. We evaluate
the ability of the two models to reproduce the key hydrological processes in the
basin with emphasis on snow accumulation and melt, streamflow and the relationships
between internal processes. Both models are capable of reproducing observed runoff
and the evolution of Moderate-resolution Imaging Spectroradiometer snow cover
adequately. In spite of WEAP's simple and conceptual approach for modelling snowmelt
and its lack of glacier representation and snow gravitational redistribution as
well as a proper routing algorithm, this model can reproduce historical data with
a similar goodness of fit as the more complex TOPKAPI-ETH. We show that the performance
of both models can be improved by using measured precipitation gradients of higher
temporal resolution. In contrast to the good performance of the conceptual model
for the present climate, however, we demonstrate that the simplifications in WEAP
lead to error compensation, which results in different predictions in simulated
melt and runoff for a potentially warmer future climate. TOPKAPI-ETH, using a
more physical representation of processes, depends less on calibration and thus
is less subject to a compensation of errors through different model components.
Our results show that data obtained locally in ad hoc short-term field campaigns
are needed to complement data extrapolated from long-term records for simulating
changes in the water cycle of high-elevation catchments but that these data can
only be efficiently used by a model applying a spatially distributed physical
representation of hydrological processes.
