报告题目:Two-Dimensional Non-stationary Mathematical Model of WaterCatchment

Abstract:In the paper the mathematical model, describing the influence ofsnow meltand rainfall run-off of given inflow and outflow of a part of a river systembeing studied intwo-dimensional in space and non-stationary in time formulations, ispresented. The Navier-Stokes equations for viscous incompressible liquid are takenas the starting point. Then, by height averaging, the shallow water equations servingas the basis for the mathematical model are obtained. Stable combinations ofboundary and initial conditions for problems with controlled run-off of water areconsidered.
