Abstract: This paper presents new weighting functions in grid generation and new discretizing scheme of momentum equations in numerical Simulation of river flow. By using the new weighting functions, the curvilinear grid can be concentrated as desired near assigned points or lines in physical plane. By using the new discretizing scheme, the problems of movable boundary and dry riverbed can be solved. As an application, the influence on flood control by Hankou flood-plain regulation is studied. The new method is applicable to the numerical simulation of river flow with irregular region and moveable boundary.
