Abstract Mathematical models based on shallow water equations and equations of bed deformations are proposed for use in designing hydraulic structures and channel straightening for large rivers in northeast Siberia (Russia). The objective of the simulation was to evaluate short time changes of channels under man-made and natural impact. The methods of hydrodynamic models application for studying of river relief change are described, and examples of simulations are demonstrated.
