Principal methods of studies of drainage basins submitted to landslides and mudflows

Abstract

A close connection is underlined existing between mudflows and landslides formation, various features and evolution of ground masses 'in terms of mud -flow processes, methods of complex studies are described in details including geological, hydro -geological, hydrological and landscape studies. An importance of remote sensing (space photographs etc.) is emphasized for landslides and mudflows studies as well as experiments. Mapping technique is recommended, and methods of stationary observations are proposed.
