“…The difference between discharges available at Namgia and Bhakra provided the total discharge from the study area. Following the trends of variation in discharge during a year, the period November-October was considered as the hydrological year, as used by Gupta et al (1982) in their study of the Beas River basin, which adjoins the present study basin. Remote sensing data were used to obtain snow-covered area data for the study period to prepare snow cover depletion curves.…”

A conceptual snowmelt model, which accounts for both the snowmelt and rainfall runoff was developed and applied for daily streamflow simulation for the Satluj River basin located in the western Himalayan region. The model, designed primarily for mountainous basins, conceptualizes the basin as a number of elevation zones depending upon the topographic relief. The basic inputs to the model are temperature, precipitation and snow-covered area. The snowmelt is computed using the degree-day approach and rain induced melting was also considered. The model was calibrated using a data set of three years (1985/86-1987/88) and model parameters were optimized. Using these optimized parameters, simulations of daily streamflow were made for a period of six years (1988/89-1990/91 and 1996/97-1998/99). The model performed well for both calibration and simulation periods. The model was also used to estimate the contribution from the snowmelt and rainfall to the seasonal and annual flows.

“…Rapid melting of snow, and thus the quick disappearance of SCA in lower elevations, was reported by Kattelman (1997). Gupta et al (1982) derived a logarithmic relationship between SCA and the volume of seasonal snowmelt runoff for Himalayan basins. These studies support the exponential relationship between SCA and CMAT used in this study.…”

Monitoring the change of snow-covered area (SCA) in a basin is vitally important for optimum operation of water resources, where the main contribution comes from snowmelt. A methodology for obtaining the depletion pattern of SCA, which is based on satellite image observations where mean daily air temperature is used, is applied for the 1997 water year and tested for the 1998 water year. The study is performed at the Upper Euphrates River basin in Turkey (10 216 km 2 ). The major melting period in this basin starts in early April. The cumulated mean daily air temperature (CMAT) is correlated to the depletion of snow-covered area with the start of melting. The analysis revealed that SCA values obtained from NOAA-AVHRR satellite images are exponentially correlated to CMAT for the whole basin in a lumped manner, where R 2 values of 0.98 and 0.99 were obtained for the water years 1997 and 1998, respectively. The applied methodology enables the interpolation between the SCA observations and extrapolation. Such a procedure reduces the number of satellite images required for analysis and provides solution for the cloud-obscured images. Based on the image availability, the effect of the number of images on the quality of snowmelt runoff simulations is also discussed. In deriving the depletion curve for SCA, if the number of images is reduced, the timing of image analysis within the snowmelt period is found very important. Analysis of the timing of satellite images indicated that images from the early and middle parts of the melt period are more important.Key words cumulative mean daily temperature; NOAA-AVHRR images; snow-covered area; snowmelt runoff; Turkey Modélisation de la variation temporelle de la surface enneigée à partir d'images satellitaires pour la simulation/prévision de l'écoulement de fonte nivale en Turquie Résumé Suivre l'évolution de la surface enneigée dans un bassin est d'une importance vitale pour la gestion optimale des ressources en eau, lorsque la contribution principale correspond à la fonte nivale. Une méthodologie d'obtention des courbes de diminution de la surface enneigée, qui s'appuie sur des observations satellitaires et qui utilise la température moyenne journalière de l'air, est appliquée à l'année hydrologique 1997 et testée pour l'année hydrologique 1998. L'étude est réalisée pour le bassin supérieur de l'Euphrate, en Turquie (10 216 km 2 ). La période principale de fonte dans ce bassin commence début avril. La température moyenne journalière cumulée de l'air (TMJC) est corrélée avec la réduction de la surface enneigée et avec le début de la fonte. L'analyse montre que les valeurs de surface enneigée obtenues à partir d'images satellitaires NOAA-AVHRR sont corrélées de manière exponentielle avec la TMJC du bassin dans sa globalité, avec des valeurs de R² respectivement égales à 0.98 et 0.99 pour les années hydrologiques 1997 et 1998. La méthodologie appliquée permet de réaliser des interpolations entre les observations de surface enneigée, ainsi que des extrapolations. Une tell...

“…Elles concernent généralement la prévision des crues sur de grands bassins versants dans le but d'amé-liorer la gestion des cours d'eau. Le suivi du stock neigeux fait appel à des méthodes variées telles que, la mesure des paramètres nivoclimatiques, le bilan énergétique et la té-lédétection appliquée sur de grands bassins [1]. L'étude réalisée ici sur le bassin de Chavanette (Morzine-Avoriaz) concerne les réponses à la fusion nivale, d'un aquifère calcaire et fissuré, au niveau d'une source pérenne d'altitude (1 850 m) alimentée par un petit bassin versant dont la totalité de la surface reste enneigée sur la période étudiée.…”
