Abstract

The results of the numerical simulations of the dynamics of shallow waters for Volga-Akhtuba Floodplain are discussed. The mathematical model is based on the system of Saint-Venant equations. Numerical solution applies a combined Lagrangian-Eulerian (cSPH-TVD) algorithm. We have investigated the features of the spring flood in 2011 and found the inapplicability of the hydrodynamical model with the constant roughness coefficient [Formula: see text]. We have found a good agreement between the results of numerical simulations and the observational data at gauging stations which allows us to estimate [Formula: see text] in low water [Formula: see text] and the maximum water level in the river Volga [Formula: see text] 0.06–0.07.
