“…The unique landscape of 20000 km 2 Volga-Akhtuba floodplain (VAF) depends on special features of the interfluve hydrological regime. During the spring flood period the area between the Volga and Akhtuba rivers is heavily flooded [1,2,3], that ensures a special composition of flora and fauna and possibility of agricultural use of the area including the development of magnificent gardens and melon fields. The floodplain is also the basis for the fish reproduction at the Lower Volga region [4].…”

We investigate of a special dam optimal location at the Volga river in area of the Akhtuba left sleeve beginning (7 km to the south of the Volga Hydroelectric Power Station dam). We claim that a new water-retaining dam can resolve the key problem of the Volga-Akhtuba floodplain related to insufficient water amount during the spring flooding due to the overregulation of the Lower Volga. By using a numerical integration of Saint-Vacant equations we study the water dynamics across the northern part of the Volga-Akhtuba floodplain with taking into account its actual topography. As the result we found an amount of water V A passing to the Akhtuba during spring period for a given water flow through the Volga Hydroelectric Power Station (so-called hydrograph which characterises the water flow per unit of time). By varying the location of the water-retaining dam x d , y d we obtained various values of V A (x d , y d ) as well as various flow spatial structure on the territory during the flood period. Gradient descent method provide us the dam coordinated with the maximum value of V A . Such approach to the dam location choice let us to find the best solution, that the value V A increases by a factor of 2. Our analysis demonstrate a good potential of the numerical simulations in the field of hydraulic works.

We investigate of a special dam optimal location at the Volga river in the area of the Akhtuba left sleeve beginning (7 km to the south of the Volga Hydroelectric Power Station dam). We claim that a new water-retaining dam can resolve the key problem of the VolgaAkhtuba oodplain related to insucient water amount during spring oodings due to the overregulation of the Lower Volga. Using a numerical integration of Saint-Vanant equations we study the water dynamics across the northern part of the Volga-Akhtuba oodplain taking into account its actual topography. As the result we found an amount of water V A passing to the Akhtuba during spring period for a given water ow through the Volga Hydroelectric Power Station (so-called hydrograph which characterises the water ow per unit of time). By varying the location of the water-retaining damas well as various ow spatial structure on the territory during the ood period. Gradient descent method provides the dam coordinated with the maximum value of V A . Such approach to the dam location choice let us nd the best solution, that the value V A increases by a factor of 2. Our analysis demonstrates a good potential of the numerical simulations in the eld of hydraulic works.
