Abstract

The arctic alpine landscape on Ammassalik Island features catchment with varying glacier coverage. Climatic data from three stations were analyzed, water balances were calculated, and the problems in estimating the water balance in this type of catchment are discussed. Potential evapotranspiration according to Makkink (1957) varies from 379 mm year−1 to 400 mm year; corrected precipitation varies between 1036 mm year−1 and 1255 mm year−1; and modeled runoff from 702 mm−1 yearto 1708 mm year−1 on a 4-year average. Comparisons of modeled runoff with measured values indicate that the higher runoff values, based on corrected precipitation, are in the right order of magnitude. The high measured runoff values can partly be explained by excess runoff from glaciers in the area having a negative annual mass balance.
