having a hydrological regime influenced by snow and glacial melt show signs of sensitivity
to temperature variations.
The mean annual catchment-averaged temperature difference between the 25% warmest and
25% coldest years ranges from 1.5°C to 1.8°C depending on catchment. It is found that a

were measured in the accumulation zone and a dense net-
work of point measurements were carried out in the abla-
tion zone. Digital Elevation Models (DEMs) of the surface
and bedrock were created from these data (Fig. 2; Björns-
son and Pálsson, 2004). The estimated errors are at most
1–5 m (bias less than 1 m) for the surface
