Summary
This paper presents the results of studies on the development and application of a generalized finite element model for the computation of two-dimensional unsteady free surface flows with emphasis on river problems. The model formulation is based on the complete depth-integrated shallow water equations. The finite element procedure employs linear triangular elements and linear shape functions with Galerkin’s method of weighted residuals. The time integration is carried out implicitly and the scheme is unconditionally stable. The computed results are in good agreement with published data and analytical solutions. The model has been tested on different problems and has been found to be very efficient.
