Glacier volume change forecasts
Oerlemans et al. (1998) conducted modelling experiments for a sample of 12 glaciers and ice caps, to determine volume changes under a range of temperature and precipitation forcings (Fig. 3). The range of glacier respon...

Seasonal patterns of precipitation and runoff
The infuence of glaciers on seasonal distribution of river fow is strongly dependent on annual temperature and precipitation cycles, and the proportion of the catchment occupied by glacier ice. Figure 4 compares precip...

Salzach river discharge, Austrian Alps
Simulated contributions of glacier melt (frn/ice melt) to annual total runoff were calculated between 1 and 4%. In the period 1999–2000, when the glacier mass balance of Goldbergkees and Stubacher Sonnblickkees have been...
