Study of Spatial Distribution and Occurrence Frequency of Ice Jams in Rivers of the Votkinsk Reservoir Catchment

V. G. Kalinin

In this paper, ice jams were studied and systemized for the first time for the Votkinsk reservoir catchment. For this purpose, observational and pooling data were used. The cartographic and attributive databases of sites where the jams occur were created by using GIS-technologies what allows obtaining their exact georeferences. Performed analysis of the studied river sections allowed revealing the main reasons of jamming.
