“…While there is a huge number of studies around the world on the impact of climate change on watershed hydrological processes, most of these studies have focused on projections of future hydrological conditions (Liu et al ., ; Miller et al ., ; Huss et al ., ; Pellicciotti et al ., ; Tao et al ., ; Yucel et al ., ). On the contrary, this study used historical records to determine the effects of temperature and precipitation change on watershed hydrological processes.…”

Abstract:The processes by which climate change affects streamflow in alpine river basins are not entirely understood. This study evaluated the impacts of temperature and precipitation changes on runoff and streamflow using glacier-enhanced Soil and Water Assessment Tool model. The study used observed and detrended historical meteorological data for recent decades to analyse individual and combined effects of temperature and precipitation changes on snow and glacier melts and discharges in the Sary-Djaz-Kumaric River Basin (SRB), Tianshan Mountains. The results showed a 1.3% increase in annual snowmelt in the basin, mainly because of an increase in precipitation. Snowmelt in the basin varied seasonally, increasing from April through May because of increasing precipitation and decreasing from July through September because of rising temperature. Glacier melt increased by 5.4%, 5.0% of which was due to rising temperature and only 0.4% due to increasing precipitation. Annual streamflow increased by 4.4%, of which temperature and precipitation increases accounted for 2.5% and 1.9%, respectively. The impacts of temperature and precipitation changes on streamflow were especially significant after 1980 and even more so in September. Glacier melt, due to temperature rise, was the dominant driver of increasing streamflow in the glacier-dominated SRB, Tianshan Mountains.

“…However, most hydrological modeling does not include glacier melt and accumulation processes. For example, Liu et al (2010) failed to account for the glacier processes in the VIC model in the Tarim River; Peng and Xu (2010) missed the glacier module in Xinanjiang and TOPMODEL;and Fang et al (2015a) failed to account for glacier processes, though the glacier melt could contribute up to 10 % of discharge of the Kaidu River basin. Similarly, in their research on the Yarkand River basin, Liu et al (2016a) neglected the influence of glacier melt in the SWAT and MIKE-SHE models, even though the glacier covered an area of 5574 km 2 .…”

Abstract. Meltwater from glacierized catchments is one of the most important water supplies in central Asia. Therefore, the effects of climate change on glaciers and snow cover will have increasingly significant consequences for runoff. Hydrological modeling has become an indispensable research approach to water resources management in large glacierized river basins, but there is a lack of focus in the modeling of glacial discharge. This paper reviews the status of hydrological modeling in glacierized catchments of central Asia, discussing the limitations of the available models and extrapolating these to future challenges and directions. After reviewing recent efforts, we conclude that the main sources of uncertainty in assessing the regional hydrological impacts of climate change are the unreliable and incomplete data sets and the lack of understanding of the hydrological regimes of glacierized catchments of central Asia. Runoff trends indicate a complex response to changes in climate. For future variation of water resources, it is essential to quantify the responses of hydrologic processes to both climate change and shrinking glaciers in glacierized catchments, and scientific focus should be on reducing uncertainties linked to these processes.

“…Hydrological models use observed meteorological data to simulate streamflow, and are often verified using observed streamflow or other measurable hydrological variables (Rosso 1994, Brooks et al 2007, Liu et al 2009. A model should be able to reasonably reproduce historical streamflow records, in order to be used in climate change studies, and can only be applied with confidence once the model output has been verified against observed data (Loukas et al 2002, Jewitt et al 2004.…”

The ACRU agro-hydrological modelling system was set up to simulate the impacts of climate change on the hydrological responses of the 3856-km 2 Cline River watershed, the major headwater of the upper North Saskatchewan River basin in central Alberta, Canada. The physical-conceptual ACRU model was set up to simulate all elements of the hydrological cycle on a daily time step for the 1961-1990 baseline period, to serve as the basis for later climate change impact simulations. After parameterization, the output from the ACRU model was verified against temperature, snow water equivalent, glacier mass balance, potential evapotranspiration, and two sets of long-term daily streamflow records. The multi-variable verification analyses were implemented to instil confidence that the simulated streamflow time series is based on a realistic combination of bio-physical parameters and represents the watershed behaviour in terms of annual water yields, seasonality, shape and magnitude of the hydrographs, and streamflow variability.Key words hydrological simulation model; streamflow; snow; glacier; verification; ACRU model; Canada Vérification multi-variable des processus hydrologiques dans le bassin supérieur de la rivière North Saskatchewan, Alberta, Canada Résumé Le système de modélisation agro-hydrologique ACRU a été mis en place pour simuler les impacts des changements climatiques sur les réponses hydrologiques du bassin versant de la Rivière Cline (3856 km 2 ), source majeure du bassin supérieur de la rivière North Saskatchewan dans le centre de l'Alberta, au Canada. Le modèle physique-conceptuel ACRU a été mis en place pour simuler tous les éléments du cycle hydrologique au pas de temps journalier pour la période de référence 1961-1990, pour servir de base à des simulations ultérieures des impacts des changements climatiques. Après le paramétrage, les sorties du modèle ACRU ont été vérifiées sur la température, l'équivalent en eau de la neige, le bilan de masse des glaciers, l'évapotranspiration potentielle, et deux enregistrements de long terme de débits quotidiens. Les analyses de vérification multi-variables ont été mises en oeuvre pour s'assurer que la série des débits simulés est basée sur une combinaison réaliste de paramètres biophysiques et représente le comportement du bassin versants en termes d'écoulement annuel, de saisonnalité, de forme et d'ampleur des hydrogrammes et de variabilité du débit.
