РАЗВИТИЕ ЭРОЗИОННО-АККУМУЛЯТИВНЫХ ПРОЦЕССОВ В МАЛОМ РЕЧНОМ ВОДОСБОРЕ ЮГО-ЗАПАДНОГО ПРИБАЙКАЛЬЯ В ХХ ВЕКЕ

The mean annual volumes of land-loss (15500 tons) and gully erosion (1450 tons) in the Elovka river catch basin during the period 1937-2008 were calculated. In these years, the intensity of erosion-accumulation processes changed periodically. Alterations in the land-use played the main role in the dynamics of out-wash, breaking accumulation of delivium and proluvium. Seasonal and annual differences in the amount and intensity of precipitation had additional effect on the rates of erosion-accumulative processes.
