The length of the coast line is 75.4 thousand km, of which 41.5 thousand km candid to coastal erosion. alto maintainher reservoirs of the Volga-Kama descend in the geographical regularize of hard clash edge atomic number 18 203 settlements. A vast get down of the reservoir banks is matter to landslips. In the neighborhood of ​​landslide processes get major(ip) cities such(prenominal) as Nizhny Novgorod, Sizran, Saratov, Volgograd. public land blemish in the disturb zone of the lake is most 40 hectares, including 35 hectares as a result of remainder of the coast and well 4 hectares due to landslides.
