Título del libro: General Procedure To Compute Channel Systems For Unsteady Flow Conditions.
Two main types of procedures have been employed to solve problems on channel systems working under unsteady flow conditions. The method of characteristics was widely used a few years ago and recently finite difference and finite element procedures became prefered. When there are control structures and discontinuities in the channels, all these methods are difficult to solve. Equations defining cross channel systems such as those used in sewerage are almost impossible to solve when traditional methods are employed. In this paper, a finite difference procedure will be introduced in order to reduce the problems with which design engineers need to deal. This procedure is based on two simple ideas. The first idea is to divide the channel into several consecutive segments and to establish dynamic and continuity equations inside each segment. The second idea is to set continuity equations at each one of the sections located between two neighbouring segments.
