Modeling of thermohydrodynamic processes in Lake Chany

The paper presents the results of the computer simulation of the thermohydrodynamic (THD) processes in a shallow water body based on the open software package Delft3D. The object of modeling is closed Lake Chany - the largest natural water body in Western Siberia. To construct a computer THD-model of Lake Chany digital elevation model of its basin was refined and a database containing meteorological information from coastal area stations and hydrological data of the lake and its tributaries was prepared. Simulation calculations of THD processes for open-water period in 2018 are performed. The analysis of the results showed that the constructed 2DH computer model of Lake Chany allows to reproduce the observed features of its thermal regime for the ice-free period.
