DANGER OF RIVERBED PROCESSES ON RUSSIAN RIVERS: ASSESSMENT CRITERIA, MAPPING, REGIONAL ANALYSIS

Abstract

The article discusses the danger that channel processes – the processes creating the river channel and floodplain and those occurring in them – can pose to people. Riverbed processes are among the most dynamic ones in nature: the speed of their manifestation varies from the first decades to individual months in high water and floods, i.e. they develop in full view of people. This can significantly complicate life on the banks of rivers and the use of river resources. The article deals with dangerous manifestations of riverbed processes, their causes and consequences, but the main part of the paper is devoted to the cartographic method of assessing the danger of riverbed processes: determining the danger degree and various ways of displaying it on maps. There are given examples of showing danger on previously compiled maps. In conclusion, the article provides a brief geographical analysis of the distribution of various types and the manifestation degree of dangerous riverbed processes in a variety of natural conditions in Russia.
