INVESTIGATION OF SNOW CONTROL SYSTEMS ON AN AVALANCHE SLOPE

A system of snow-deflecting fences for avalanche control, has been constructed for the first time in the USSR in 1971 on one of the avalanche slopes in Southern Sakhalin and has proved to be very effective. Despite the fact the snowfalls and blowing snow occur on Sakhalin almost frequently at temperatures from - 10 to - 2 degree C and the snow is wet, cornices have ceased to form at snow-deflecting fences and in some cases the slope remained bare throughout the winter below them. The operation of snow-deflecting fences and snow control systems on mountain slopes has been investigated by the Scientific Research Institute of Railroad Transportation since 1969. Systems for regulating snow deposition have been installed along railroads in several avalanche areas of Southern Sakhalin in 1971-1972 with allowance for the results of simulation in wind tunnels and of anemometer surveys. The method and some results of investigations are reported here.
