As a result, this found expression in conducting new for that territory engineering-geonomic studies. Both the region as a whole and its individual parts can serve as models in the study of natural processes due to the diversity of landscape-climatic belts and zones. The report contains brief data on engineering-geonomic studies conducted in the Zeravshan river basin in connection with the intensification of mudflow processes.展开更多
