EcoGIS-Simulation Software for riverbed sediments modeling

Abstract

The paper describes the EcoGIS-Simulation software and hardware complex for numerical hydrological modeling of river systems. The computing core makes it possible to carry out a non-stationary self-consistent calculation of the dynamics of surface and groundwater, as well as the transfer of entrained and suspended sediments. The main attention is paid to the organization of geoinformation support for such calculations at the stages of preparation of initial data, processing of results and their visualization. EcoGIS-Simulation software is designed to simulate non-stationary self-consistent dynamics of surface and groundwater together with the transport of entrained and suspended sediments. The strong dependence of the nature of sediment transport on the particle size in the conditions of the Medveditsa River in the vicinity of the city of Mikhailovka (Volgograd Region, Russia) is shown.
