Hydrological project at Narssaq Bræ, South Greenland, as part of the International Hydrological Decade Programme

Abstract

Narssaq river valley constitutes the third Danish representative area investigated in the UNESCO International Hydrological Decade (IHD) (see Larsen, 1970). Field work continued there in 1971 from the beginning of June to the end of August. As proposed by UNESCO/IASH (1970) a drainage basin selected for a combined balances project should meet the following requirements: (a) the basin should be well defined hydrologically and include a glacier covering at least 30% of the drainage area, (b) the gIacier should be normal in regard to size, accumulation, activity and other characteristics and (c) there should be a possibility of measuring simultaneously heat, mass and water balances for at least three years during the IHD.
