A CRITICAL EXAMINATION OF THE REQUIREMENTS FOR MODEL SIMULATION OF WIND-INDUCED EROSION/DEPOSITION PHENOMENA SUCH AS SNOW DRIFTING

The requirements are examined for correct model simulation, in wind tunnels, of wind-induced erosion and deposition phenomena such as snow drifting. The similarity analysis draws heavily on physical analysis of the saltation process and on experimental evidence. The important similarity criteia are identified and the limit above which the process is insensitive to Reynolds number is tentatively established. Modelling procedures, including a procedure for selecting model particles, are outlined. It will often be impracticable to simultaneously satisfy all the simulation requirements and the compromises involved in such cases are discussed. Simulation of these phenomena in water is shown to be inadvisable.
