Seasonal runoff forecast for Kangerluarsunnguaq near Nuuk/Godthåb, West Greenland

A hydro-electric power station may be built to aupply Nuuk/Godth6b with power from the mid-1990s. The station will use water from the Kangerluarsunnguaq basin south of Nuuk. The basin only has a slight glacier cover and glaciers have little effect on runoff variations. However, the June to October runoff is highly correlated with snow accumulation measured on a small glacier in the basin, i.e. a correlation coefficient of 0.84. As the accumulation data are available in May, they can be used to forecast runoff during the following summer. As an example, accumulation in May 1989 was exceptionally low, i. e. O. 45 m water, and the runoff for the 1989 summer should have been low also, i. e. 93 x 106 1113. The measurements of accumulation will be continued for several more years to improve the correlation with runoff. Test forecasts will also be issued to interested parties.
