Abstract

The paper presents a numerical model of planimetric currents in channel systems of a complicated spatial configuration. The model is based on the two-dimensional Saint–Venant equations. The influence of a non-homogeneous flow structure on the admixture transport processes in the water is studied. Calculation of current and passive substance redistribution is presented for a 16-km stretch of the Ob river near the city of Novosibirsk.
