Abstract |
A finite difference scheme was developed to integrate the St. Venant equations over a wide range of transient flow conditions. The scheme was incorporated into a useful computer program. Systematic testing compared the difference scheme with observed data and linearized analytical solutions. The weighted residual method using the Galerikan technique of minimizing proved to be a relatively simple method for deriving a minimum error finite difference scheme. Solution of the set of simultaneous algebraic equations generated by the implicit difference scheme was effected using the influence function method. This provides a very efficient procedure for solving the equations associated with a network of channels. (WRSIC abstract) |
