Abstract: A hydro-electric power company in Switzerland, Kraftwerke Oberhasli (KWO), is planning a new reservoir with a storage level about 110m higher than the existing Grimselsee (Lake of Grimsel), which would cause flooding over 800m length the terminus of Unteraargletscher with consequent calving into the Grimselsee. This paper deals with the problem of calving waves which could splash over the dam. First, the calving events caused by the ice masses that may break off from the glacier through buoyancy or gravity are assessed with two-dimensional modelling of glacier flow. The calving events as defined are simulated la a hydraulic model which includes the glacier front, the whole reservoir and the dam at a scale of 1:250, in which the induced calving waves were measured. The results of the measured calving waves show that calving events can be simulated in a hydraulic model at this scale to obtain the calving waves expected in the planned reservoir
