Morphological activity of a diverted glacier stream in Western Norway

In connection with the construction of a tunnel collecting water beneath a glacier (Bondhusbreen/Folgefonni) in SW Norway the amount of sediments transported by meltwater has been investigated. According to the values obtained the volume of the sedimentation chamber which has to take a one-years-amount of sediment was fixed at 5000 m³. In 1978 there has been a sedimentation of 3000 m³ of coarse material. The results obtained are not only of practical value, but also of scientific interest.
