A numerical model for the simulation of tides in estuarial networks

Abstract

A one-dimensional numerical model, based on Preissmann scheme for the discretization of shallow water wave equations, has been developed and applied to the Mcghna Delta, consisting of 15 branches connected at 8 junctions with 3 sea-ward and river-end  boundaries. The model was calibrated by adjusting Manning's roughness coefficient. Considering the simplified schematization of the delta and limitations imposed by insufficient data, the results of model calibration and validation were found to be satisfactory.
