Steppe rivers (Eja, Beysug, Chelbas et al.) occupy a vast Azov-Kuban plain, whose total length reaches 4800 km and catchment area of the entire hydrological network of up to 24 000 km. Dams and silting increase flooding of agricultural land and many rivers severely degraded with a reduction of its water content and its quality. Landscapes of the steppe zone occupy a middle reaches of the large ...
