Abstract

The paper presents a 3D model for a deep flowing water body based on the open software package Delft3D to describe and predict thermohydrodynamic (THD) processes in existing and projected reservoirs of Siberia. As an example, a 3D model for non-stationary THD processes of the Krasnoyarsk Reservoir was built and tested. For its construction, we developed a Digital Relief Model (DRM) for the Krasnoyarsk Reservoir basin, generated a finite-difference grid, identified the empirical constants and formulated the initial and boundary conditions. Numerical simulation of current velocity and water temperature of the reservoir for spring/summer of the scenario year was performed.
