Evaluation of stormwater networks via numerical simulation method

Stormwater originating from rainfall on an urban area flows in the stormwater network in a way that can be inspected by real time hydraulic simulation. The flow height and velocity occuring in the stormwater network?s conduits can be stated by the Saint Venant equation system aka shallow water equations. In this thesis the hyperbolic Saint Venant equations are solved by an algorithm based on the MacCormack scheme which is a finite difference method. In the access holes, which are taken as the drainage system entrance points for the surface flows, continuity and energy equations are not applied separately and it is assumed that rain water entering from the access holes pass directly to the conduits. It has been shown that, results obtained during the numerical simulation are consistent with the input data.
