This paper deals with the flood routing in river networks where the solution cannot be obtained from hydrologic routing methods. An improvement for dynamic unsteady one-dimensional (1-D) flow simulation based on Preissmann implicit finite difference scheme with simultaneous solution is developed. The river networks aredescribed by a set of basic river reaches between two nodes. A procedure for automatically creating the order for controlling double-sweep is established. It then is applied for flood routing in the river network of a part of the Red river basin, Vietnam. From the results, the improvement is expected as an effective treatment for dynamic flood routing in river networks of dendritic type.
