Flow mechanisms and resistances in the debris streams of rock slides

Körner, H. J.

Summary For the calculation of avalanche movements, three idealistic models will be presented. First, the “Gliding block motion” with a constant friction coefficient. In this case the velocity can be estimated from the straight energy-line. Next, are the two turbulent motions, the “Rolling motion” and the “Scattering motion”. The flow resistance of these two movements can be calculated approximately, given the steady uniform flow conditions with a constant density. These flow coefficients are used to demonstrate the material properties which play a part in real mountain slides and avalanches.
