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.
