Man-induced gullies formation under permafrost conditions

Abstract

Man-induced gullies formation under cold climatic conditions is discussed with special reference to one of newly built-up regions at the NE West Siberia. The main cause of the process is proved to be sharp increase in run-off (resulted from snow drift melting and sewage). Three stages of man-induced gullies development are distinguished, and the first and second stages duration is obtained.
