July 1989


Seasonal accumulation of snow and the subsequent snowmelt runoff are dominant features of alpine basins. Direct measurements of snow reserves are hampered by the difficult access and avalanche hazards in the remote parts of a mountain basin. During the snowmelt period, the snow covered area is gradually decreasing which affects the meltwater production. Satellite monitoring of snow cover enables the snow reserves to be indirectly evaluated. It provides data on the changing areal extent of snow cover which facilitates runoff forecasts. All available satellite recordings have been evaluated for the high alpine regions Tavanasa and Sedrun and depletion curves have been derived for the runoff season 1985. Interest is focused on getting remote sensing information from very different sensors such as Landsat-MSS, SPOT-XS, and NOAA/AVHRR by quasi real-time access. The data has to be integrated into a multi-temporal dataset for the analyses and in order to use them for operational discharge forecasts for a hydroelectric scheme.
