Abstract The reduced 3D model of the shallow and lengthy stream is tested numerically. This mathematical model is one of several that proposed in [1]. For it verification a number of calculations with finite-element package COMSOL was done. The values of longitudinal velocity were calculated in the framework of reduced model formulas through numerical solution of the initial- boundary value problem for the free surface displacement function. These values were compared with data of laminar and turbulent CFD COMSOL calculations. The obtaining results demonstrate that the hydrodynamics of the shallow and lengthy bed-stream flow is described adequately by proposed reduced model.
