 Summary:
 This paper presents the development of a one-dimensional, looped river network model with a dam as an internal boundary condition. The one-dimensional de Saint-Venant equations were discretized using the Preissmann’s scheme. The discretized equations are then linearized and solved using the Newton-Raphson’s iterative algorithm combined with the Thomas (double-sweep) algorithm. In order to accommodate flow simulation in looped river networks, the regular equations are supplemented with additional equations necessary when simulating flow in complex river systems.
