Abstract

The report is devoted to two issues of erosion and riverbed development processes within Volgograd agglomeration. The first one describes erosion processes and relief forms that constitute the morph sculpture characteristic of the Lower Volga left bank where Volgograd is situated. Its destruction in the recent decades has brought harmful effects onto the agglomeration in the form of under flooding and observable decline in the living conditions of the population. The other issue is about the shrinkage of the Volga-Akhtuba alluvial plain resulting from the deficiency in water release by hydro electric plant in the period of spring flood. The problem of water release can be settled only by the federal authorities.

Keywords: erosion system, gully-erosion system destruction, underflooding, social-ecologic effects, hydrogeotechnic system, steppezation of the alluvial plain, ecologic regime of the spring flood
