AbstractThe salinity intrusion in the Bang Pakong River does not only create a problem for agriculture in the catchment, but al so for the industrial developments along the river side. The quality of the river water is largely depending on the intrusion salt sea water. This study presents a predictive mathematical model of the one dimensional unsteady salinity intrusion in the Bang Pakong River. A numerical solution has been attained by the formulation of finite difference method of an implicit scheme. The basic continuity, momentum and salt balance equations have been used in developing this model. Initial and boundary values were used to obtain the space and time-varying salinity distribution along the river. The model results were calibrated with observed values at different stations along the river. Specifying only the boundary conditions such as the fresh water hydrographs and the tidal elevations at the river mouth, it becomes possible to predict the time-varying salinity intrusion by means of this model .
