Abstract

A mathematical model is presented for studying the hydrodynamic dispersion of pollutants discharged in coastal areas near a river mouth during flooding. The hydrodynamic process is represented in a 2D depth integrated system and the solute is assumed non-reactive. The model is numerically solved by finite differences characterized by an appropriate algorithm which is explicit to describe the field of motion and implicit to integrate the transport equation. 1. Introduction Within the framework of pollution problems in coastal waters, areas near river mouths assume particular technical and scientific interest. Due to the possible presence of many pollution sources in the hydrographic basin (eg. domestic sewage, toxic substances from industrial discharges, surfa
