text: Monitoring and estimating mountain snowpack mass over regional scales is still
a challenge because of the inadequacy of observational networks in capturing spatiotemporal
variability, and limitations in remotely sensed retrievals. Recent work using
C-band synthetic aperture radar (SAR) backscatter data from the Sentinel-1 satellite
mission has shown good promise for tracking mountain snow depth over specific
northern hemisphere ranges, although the broader potential is still unknown. Here,
we extend the new Sentinel-1 based modeling framework beyond the northern hemisphere
by only utilizing globally available input data, and evaluate different model
parametrization and model performance over the Chilean and Argentine Andes mountains,
which contain the largest mountain snowpack in the southern hemisphere. The accuracy
of Sentinel-1 snow depth estimates is evaluated against an extensive in situ network
available for the region. Satellite-retrieved snow depth is found to have poorer
performance across the Andes than observed for northern hemisphere mountain ranges
because of greater sensitivity to evergreen forest cover and shallower snowpacks.
The algorithm does offer some skill but performance is variable and site-dependent.
Algorithm performance is best over regions with limited evergreen forest cover
(<15%) and snow depths greater than 0.75 m, although the retrievals over-estimate
snow depth across most sites. Systemic errors for specific snow classes and across
different snow depths are shown, highlighting specific areas in need of further
investigation and development.

text: The topography of a landscape regulates the spatial distribution of water
and energy fluxes, which are main drivers of vegetation and soil carbon and nutrient
dynamics. Despite the recognized role of topography in mediating such processes,
quantifying and predicting the spatial distribution of carbon and nutrient fluxes
and stocks in highly heterogeneous landscapes remains challenging. The main limitations
stem from the prevalence of largely decoupled modeling approaches which fail to
concurrently account for ecohydrological and biogeochemical processes as well
as the lack of adequate frameworks describing the links among topography, water
and energy balances, and soil biogeochemical dynamics. Here, we extend the capabilities
of the mechanistic ecohydrological model Tethys-Chloris-Biogeochemistry (T&C-BG)
by including a soil carbon and nutrient routing module in the distributed model
version. The newly developed T&C-BG-2D model is validated against long-term hydrological
and biogeochemical measurements from the Hafren catchment in Wales (UK) and the
Erlenbach catchment in the Swiss pre-Alps. The model successfully captures carbon
and nutrient concentrations and dynamics in these catchments, with relative differences
between simulated and observed median values of between −4% and −0.3% for dissolved
organic carbon, and between 1% and 20% for ammonia. A sensitivity analysis in
the Erlenbach basin suggests that elevation explains over 80% of the observed
spatial patterns, followed by topographic wetness index (12.6%), aspect (2.9%),
and curvature (2.1%). These findings underscore topography's critical role in
shaping water, carbon, and nutrient dynamics, which cannot be reflected in plot-scale
simulations neglecting spatial interactions and topographic effects.

text: Tidal freshwater marshes are threatened by seawater intrusion globally due
to freshwater discharge reduction and sea-level rise. However, terrestrial nitrate
(NO3−) transport responding to seawater intrusion remains poorly understood in
tidal marshes. After validation against laboratory experiments, numerical simulations
were conducted to analyze seawater intrusion effects on terrestrial NO3− transport
and transformation in tidal marsh aquifers. Results reveal that seawater intrusion
noticeably affects NO3− transport from the marsh aquifer to the tidal creek. Seawater
intrusion results in an upper saline plume and a saltwater wedge within the aquifer,
which markedly narrows the discharge outlet width of the NO3− plume and intensifies
the peak NO3− flux across the creek bank. Consequently, both the NO3− removal
efficiency and total nitrogen gas load to the creek decrease substantially after
seawater intrusion. This is because the reduction of the transit time and the
mixing zone width of the NO3− plume after seawater intrusion weakens denitrification.
Sensitivity analyses indicate that the difference of the NO3− removal efficiency
before and after seawater intrusion depends on soil properties. A larger unsaturated
flow effect, saturated hydraulic conductivity or effective porosity leads to a
greater difference of the NO3− removal efficiency before and after seawater intrusion.
The predicted decrease of the NO3− removal efficiency after seawater intrusion
is consistent with existing field data.

text: High Mountain Asia (HMA) is among the most vulnerable water towers globally
and yet future projections of water availability in and from its high-mountain
catchments remain uncertain, as their hydrologic response to ongoing environmental
changes is complex. Mechanistic modeling approaches incorporating cryospheric,
hydrological, and vegetation processes in high spatial, temporal, and physical
detail have never been applied for high-elevation catchments of HMA. We use a
land surface model at high spatial and temporal resolution (100 m and hourly)
to simulate the coupled dynamics of energy, water, and vegetation for the 350
km2 Langtang catchment (Nepal). We compare our model outputs for one hydrological
year against a large set of observations to gain insight into the partitioning
of the water balance at the subseasonal scale and across elevation bands. During
the simulated hydrological year, we find that evapotranspiration is a key component
of the total water balance, as it causes about the equivalent of 20% of all the
available precipitation or 154% of the water production from glacier melt in the
basin to return directly to the atmosphere. The depletion of the cryospheric water
budget is dominated by snow melt, but at high elevations is primarily dictated
by snow and ice sublimation. Snow sublimation is the dominant vapor flux (49%)
at the catchment scale, accounting for the equivalent of 11% of snowfall, 17%
of snowmelt, and 75% of ice melt, respectively. We conclude that simulations should
consider sublimation and other evaporative fluxes explicitly, as otherwise water
balance estimates can be ill-quantified.

text: High Mountain Asia (HMA) is among the most vulnerable water towers globally
and yet future projections of water availability in and from its high-mountain
catchments remain uncertain, as their hydrologic response to ongoing environmental
changes is complex. Mechanistic modeling approaches incorporating cryospheric,
hydrological, and vegetation processes in high spatial, temporal, and physical
detail have never been applied for high-elevation catchments of HMA. We use a
land surface model at high spatial and temporal resolution (100 m and hourly)
to simulate the coupled dynamics of energy, water, and vegetation for the 350
km2 Langtang catchment (Nepal). We compare our model outputs for one hydrological
year against a large set of observations to gain insight into the partitioning
of the water balance at the subseasonal scale and across elevation bands. During
the simulated hydrological year, we find that evapotranspiration is a key component
of the total water balance, as it causes about the equivalent of 20% of all the
available precipitation or 154% of the water production from glacier melt in the
basin to return directly to the atmosphere. The depletion of the cryospheric water
budget is dominated by snow melt, but at high elevations is primarily dictated
by snow and ice sublimation. Snow sublimation is the dominant vapor flux (49%)
at the catchment scale, accounting for the equivalent of 11% of snowfall, 17%
of snowmelt, and 75% of ice melt, respectively. We conclude that simulations should
consider sublimation and other evaporative fluxes explicitly, as otherwise water
balance estimates can be ill-quantified.

text: 'Investigating modifications in the hydrological cycle is essential to understand
the impacts of climate change on ecosystems. This study assesses the change in
the velocity of the water cycle over land at the global scale, whereas previous
studies have mostly focused on changes in the atmospheric water cycle. The hydrological
acceleration is quantified by a decrease in average residence time (RT) of water
in the first meter of soil. The soil water RT is shown to be sensitive to the
soil texture and seasonality of hydroclimatic variables. Despite substantial local
variability, most of the RTs are in the range of 50–300 days. The global mean
soil water RT declined at a rate of −2.30 and −0.36 days decade−1 (−1.6 to 1.0
days decade−1 the range of nine models) from 2001 to 2020 as measured by reanalysis
and CMIP6 simulations for the historical scenario, respectively, which corresponds
to −6.8 and −1.1 days °C−1 when expressed per degree of global warming over land.
This acceleration is projected to continue at a rate of −1.35 days decade−1 (−3.4
to 0.0 days decade−1 the range of nine models) or −2.2 days °C−1 during the period
2015–2100 under the most extreme emission scenario: SSP 585. Changes in precipitation
dominantly drive the acceleration of the terrestrial water cycle compared to changes
in evapotranspiration. Rising temperatures and increasing carbon dioxide have
opposite effects on the speed of the terrestrial water cycle with compensatory
roles keeping RT relatively unchanged in the absence of PR trends.'

text: Hydrological, ecohydrological, and terrestrial biosphere models depend on
pedotransferfunctions for computing soil hydraulic parameters based on easily
measurable variables, such as soil texturaland physical properties. Several pedotransfer
functions have been derived in the last few decades, providingdivergent estimates
of soil hydraulic parameters. In this study, we quantify how uncertainties embedded
inusing different pedotransfer functions propagate to ecosystem dynamics, including
simulated hydrologicalfluxes and vegetation response to water availability. Using
a state-of-the-art ecohydrological model applied at79 sites worldwide, we show
that uncertainties related to pedotransfer functions can affect both hydrologicaland
vegetation dynamics. Uncertainties in evapotranspiration, plant productivity,
and vegetation structure,quantified as leaf area, are in the order of ∼10% at
annual time scales. Runoff and groundwater rechargeuncertainties are one order
of magnitude larger. All uncertainties are largely amplified when small-scaletopography
is taken into account in a distributed domain, especially for water-limited ecosystems
with lowpermeability soils. Overall, pedotransfer function related uncertainties
for a given soil type are higher thanuncertainties across soil types in both hydrological
and ecosystem dynamics. The magnitude of uncertainties isclimate-dependent but
not soil type-dependent. Evapotranspiration, vegetation structure, and plant productivityuncertainties
are higher in water-limited semiarid climates, whereas groundwater recharge uncertainties
arehigher in climates where potential evapotranspiration is comparable to precipitation.

text: 'Model fidelity and accuracy in process representations have been the crux
of scientific hydrological modeling, creating a pressing need for a better linkage
between the development of hydrological models and the growing number of data
sources and measurement techniques. Improved representation of process dynamics
in hydrological models can provide new insights into complex hydrological systems
and point out less understood natural phenomena that need further investigation.
This special issue includes contributions that offer potential solutions and strategies
to improve and test the representation of hydrological processes. We have organized
the special issue contributions into four topical categories: (a) Beyond streamflow,
which looks into the power of complementary data sources in addition to traditionally
used streamflow for process inference. (b) Challenge of subsurface hydrology,
that reflects on lesser understood processes under the surface and their impact
on the model structure. (c) Evaporation in hydrological modeling, linking ecological
aspects to the hydrological functioning of the natural system. Finally, (d) top
down vs. bottom up modeling approaches, relied upon for process representation
analysis. The special issue and our reflection on the contributions present a
snapshot of ongoing efforts for integrating new concepts, knowledge, and data
in process representation in hydrological models.'

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: 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: Groundwater can have a critical role in sustaining the functioning of natural
ecosystems during droughts, especially in dry and seasonally dry climates. However,
the response to droughts of ecosystems embedded in urban areas is not well known.
This study investigates how different scenarios of groundwater availability control
the water balance and vegetation productivity of two urban reserves hosting native
vegetation in the Melbourne metropolitan area, Australia. Using a mechanistic
ecohydrological model supported by field observations, long-term simulations were
run to explore the impact of groundwater flow on water, carbon, and energy fluxes
under present climatic conditions, including the Millennium Drought (2001–2009),
and in response to perturbations in key environmental variables (air temperature,
atmospheric CO2 concentrations, and rainfall). It was found that the presence
of a water table and its capillary fringe within the root depths supports ecosystem
transpiration and vegetation productivity. The effects of declining groundwater
were found to be more severe in predominantly sandy soils because of the lower
water holding capacity, identifying that the water status of vegetation differs
significantly depending on soil type. Differences in rooting strategies and groundwater
availability also had a pivotal role in helping plants soften the impacts of increased
air temperature (Ta) and make use of higher atmospheric CO2 concentrations. Increased
Ta strongly affected evapotranspiration, enhancing the competition for water between
different vegetation types. These results provide quantitative insights of how
vegetation responds to groundwater depletion and climate variability, highlighting
the essential role of groundwater resources in urban ecosystems characterized
by seasonally dry climates.

text: Solutes in rivers often come from multiple sources, notably precipitation
(above) and generation from the subsurface (below). The question of which source
is more influential in shaping the dynamics of solute concentration cannot be
easily addressed due to the general lack of input data. An analysis of solute
concentrations and their dependence on discharge across 585 catchments in nine
countries leads us to hypothesize that both the timing and the vertical distribution
of the solute generation are important drivers of solute export dynamics at the
catchment scale. We test this hypothesis running synthetic experiments with a
tracer-aided distributed hydrological model. The results reveal that the depth
of solute generation is the most important control of the concentration-discharge
(C-Q) relation for a number of solutes. Such relation shows that C-Q patterns
of solute export vary from dilution (Ca2+, Mg2+, K+, Na+, and Cl−) to weakly enriching
(dissolved organic carbon). The timing of the input imposes a signature on temporal
dynamics, most evident for nutrients, and adds uncertainty in the exponent of
the C-Q relation.

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: 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
distances on the tongue in the direction of the main winds, suggesting spatial
distinctions that are likely induced by different processes and that should be
taken into account when extrapolating snow depth from limited samples.

text: Water transit times and flow pathways are crucial elements in characterizing
catchment hydrologic response. Understanding their variability in space and time
sheds light on the link between discharge formation and water quality at the catchment
scale. Here, we introduce a novel modeling framework to explore water transport
mechanisms using the Hafren catchment in Wales (UK) as a case study. We show that
a fully distributed hydrological model coupled with a transport component for
conservative tracers is useful in analyzing how hydrometeorological conditions
and spatial heterogeneity may affect water transit times and age distributions
in a real catchment. We use the model to track the paths of water parcels that
entered the catchment as rainfall over 2 years, labeling each day of rain individually.
There is a reasonable agreement between tracer simulations and observations, suggesting
that dynamic transit time distributions (TTDs) both forward and backward in time
can be approximated using a high spatial and temporal resolution hydrochemical
model, without assuming a priori any transit and storage selection functions at
the catchment scale. TTDs are quantified for the modeled internal dynamics of
the study catchment. TTDs conditional on a given rainfall time are mostly correlated
to the season in which the rain event occurs, whereas TTDs conditional on a given
exit time are mostly affected by catchment wetness. When TTDs for individual rainfall
events are re‐scaled as functions of cumulative discharge, they collapse around
a single common distribution, suggesting a potential characteristic catchment
function.

text: While the claim that water-carbon interactions result in spatially coherent
vegetation patterning is rarely disputed in many arid and semiarid regions, the
significance of the detailed water pathways and other high frequency variability
remain an open question. How the short temporal scale meteorological fluctuations
form the long-term spatial variability of available soil water in complex terrains
due to the various hydrological, land surface, and vegetation dynamic feedbacks
frames the scope of the work here. Knowledge of the detailed mechanistic feedbacks
among soil, plants, and the atmosphere will lead to advances in our understanding
of plant water availability in arid and semiarid ecosystems and will provide insights
for future model development concerning vegetation pattern formation. In this
study, quantitative estimates of water fluxes and vegetation productivity are
provided for a semiarid ecosystem with established vegetation bands on hillslopes
using numerical simulations. A state-of-the-science process based ecohydrological
model is used, which resolves hydrological and plant physiological processes at
the relevant space and time scales, for relatively small periods (e.g., decades)
of mature ecosystems (i.e., spatially static vegetation distribution). To unfold
the mechanisms that shape the spatial distribution of soil moisture, plant productivity
and the relevant surface/subsurface and atmospheric water fluxes, idealized hillslope
numerical experiments are constructed, where the effects of soil type, slope steepness,
and overland flow accumulation area are quantified. Those mechanisms are also
simulated in the presence of complex topography features on landscapes. The main
results are (a) short temporal scale meteorological variability and accurate representation
of the scales at which each ecohydrological process operates are crucial for the
estimation of the spatial variability of soil water availability to the plant
root zone; (b) water fluxes such as evapotranspiration, infiltration, runoff-run-on,
and subsurface soil water movement have a dynamic short temporal scale behavior
that determines the long-term spatial organization of plant soil water availability
in ecosystems with established vegetation patterns; and (c) hypotheses concerning
the hydrological responses that can lead to vegetation pattern formation have
to accommodate realistic and physically based representations of the fast dynamics
of key ecohydrological fluxes.

text: An expression that separates biotic and abiotic controls on the temporal dynamics
of the soilmoisture spatial coefficient of variation C v(h) was explored via numerical
simulations using a mechanisticecohydrological model, Tethys-Chloris. Continuous
soil moisture spatiotemporal dynamics at an exemplaryhillslope domain were computed
for six case studies characterized by different climate and vegetationcover and
for three configurations of soil properties. It was shown that abiotic controls
largely exceed theirbiotic counterparts in wet climates. Biotic controls on C
v(h) were found to be more pronounced in Mediter-ranean climates. The relation
between Cv(h) and spatial mean soil moisture h was found to be unique in wetlocations,
regardless of the soil properties. For the case of homogeneous soil texture, hysteretic
cyclesbetween C v(h) and h were observed in all Mediterranean climate locations
considered here and to a lesserextent in a deciduous temperate forest. Heterogeneity
in soil properties increased C v(h) to values commen-surate with field observations
and weakened signatures of hysteresis at all of the studied locations. Thisfinding
highlights the role of site-specific heterogeneities in hiding or even eliminating
the signature ofclimatic and biotic controls on C v(h), thereby offering a new
perspective on causes of confounding resultsreported across field experiments.

text: Extreme rainfall events are the major driver of shallow landslide occurrences
in mountainous and steep terrain regions around the world. Subsurface hydrology
has a dominant role on the initiation of rainfall-induced shallow landslides,
since changes in the soil water content affect significantly the soil shear strength.
Rainfall infiltration produces an increase of soil water potential, which is followed
by a rapid drop in apparent cohesion. Especially on steep slopes of shallow soils,
this loss of shear strength can lead to failure even in unsaturated conditions
before positive water pressures are developed. We present HYDROlisthisis, a process-based
model, fully distributed in space with fine time resolution, in order to investigate
the interactions between surface and subsurface hydrology and shallow landslides
initiation. Fundamental elements of the approach are the dependence of shear strength
on the three-dimensional (3-D) field of soil water potential, as well as the temporal
evolution of soil water potential during the wetting and drying phases. Specifically,
3-D variably saturated flow conditions, including soil hydraulic hysteresis and
preferential flow phenomena, are simulated for the subsurface flow, coupled with
a surface runoff routine based on the kinematic wave approximation. The geotechnical
component of the model is based on a multidimensional limit equilibrium analysis,
which takes into account the basic principles of unsaturated soil mechanics. A
series of numerical simulations were carried out with various boundary conditions
and using different hydrological and geotechnical components. Boundary conditions
in terms of distributed soil depth were generated using both empirical and process-based
models. The effect of including preferential flow and soil hydraulic hysteresis
was tested together with the replacement of the infinite slope assumption with
the multidimensional limit equilibrium analysis. The results show that boundary
conditions play a crucial role in the model performance and that the introduced
hydrological (preferential flow and soil hydraulic hysteresis) and geotechnical
components (multidimensional limit equilibrium analysis) significantly improve
predictive capabilities in the presented case study.

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: Interannual variability of precipitation can influence components of the hydrological
budget, affecting them directly and indirectly through adjustments in vegetation
structure and function. We investigate the effects of fluctuations of annual precipitation
on ecohydrological dynamics. Specifically, we use the advanced weather generator,
AWE‐GEN, to simulate 200 years of hourly meteorological forcing obtained by imposing
four types of precipitation annual process with identical long‐term mean. The
generated time series force a mechanistic ecohydrological model, Tethys‐Chloris.
Simulations with perturbed precipitation variability are performed for four locations
characterized by different vegetation cover and climate. The results indicate
that long‐term transpiration (T) and evapotranspiration (ET) fluxes as well as
vegetation productivity expressed as Gross Primary Production (GPP) and Aboveground
Net Primary Production (ANPP) are essentially unaffected by the imposed climate
fluctuations. This finding supports the hypothesis of a relative insensitivity,
except for water‐limited environments, of interannual evapotranspiration and vegetation
productivity to annual climatic fluctuations, which are mostly reflected in the
fluxes of deep leakage and runoff. The occurrence of short periods of favorable
meteorological conditions randomly taking place within the year was found to be
a better explanatory variable for interannual variability of ET and ANPP than
average annual or growing season conditions. The results indicated that local,
single‐site sensitivities are considerably smaller than those observed across
climatic and vegetation spatial gradients and thus an important role of ecosystem
reorganization in modifying ANPP and ET sensitivity in a changing climate is recognized.
