Abstract

Since their installation, long sea outfalls have suffered from saline intrusion. This migration of the receiving water into the outfall diffuser leads to reduced operational efficiency due to partial blockage of the system. Wave induced saline intrusion is a common phenomenon in shallow receiving waters. It is widely believed that the geometry of the outfall has a significant effect on the onset of wave induced intrusion. However, to date, a satisfactory method of assessing the influence of waves on the internal hydraulics of outfall diffusers of differing geometries has not been achieved. This document presents details of a two-dimensional numerical model to simulate sinusoidal wave generation in an open water body. The model is based on the FLUENT computat
