Schnee- und Gletscherschmelze als Baustein der hydrologischen Abflussmodellierung

Abstract

Summary: Since several years hydrological modelling has grown more important for operational applications. This is caused by the developing resources of data collection and processing systems, the increased capability of spatiooral resolution of hydrological basins by geospatial techniques and by the growing demand of runoff prediction systems. The latter are strongly related on flood forecasts and warning systems but also on forecasts of droughts, hydro energy production or ecological developments. In alpine regions the contribution of melt by snow covered and glaciered areas is of high importance for an integrated approach of the entire hydrological processes. The current paper refers on different methods of melt modelling, where the focus is on index based concepts. Furthermore the linkage of melt and runoff formation is addressed. © 2009 Springer-Verlag.
