On the zonality of the man-induced processes in the USSR

Abstract

A new classification of man-induced geomorphic processes is introduced, zonal and azonal processes being distinguished. The zonal processes are further subdivided into groups: l) those controlled by climatic zonality (such as irrigation and melioration, cultivation, timber cutting); 2) those controlled by geologic zonality (quarring, mining, placers exploitation, oil and gas production). Azonal processes include construction of water reservoirs, dams, dikes and embankments, roads, coasts protection, civil engineering.
