Abstract:

This paper presents a one-dimensional, finite element model for simulating hydrodynamic responses to various conditions on a river system by using microcomputers. Based on the Saint-Venant equations, the finite element model has been developed by adopting the Dissipative Galerkin's method of weighted residuals. This model is capable of simulating hydraulic transients in a complex river system with highly irregular cross-section geometry at any station and varying continuously from station to station along the reach. Lateral inflows, confluences, structures, and obstructions can also be included.
