Model for snowmelt runoff modelling and forecasting using satellite

A processing chain was developed for modelling and forecasting runoff in mountain basins where main contributions to discharge come from snow and glacier melt. The runoff model represents an extension of the semi-distributed Snowmelt Runoff Model (SRM) of Rango and Martinec. The processing chain includes modules for pre-processing of hydrological and meteorological input data at different temporal and spatial scales, and for assimilating snow covered area derived from satellite images in the model.

The runoff forecasting tool runs automatically, utilising numerical meteorological forecast data and satellite sow maps as input. The software was successfully tested in real time in spring 2005, providing forecasts of daily runoff 1 to 7 days ahead in watersheds of the Eastern Alps. The runoff forecasting tool is ready to be implemented in an operational runoff modelling and forecasting system.
