Water Quality Modeling in Persian Gulf Considering Thermal Pollution Sources of Industrial Plants

Abstract

Numerical modeling is carried out to investigate the spreading pattern of industrial wastewater released from coastal refineries and power plant into thePersian Gulf. The pollutant sources due to the wastewater outfall of the coastal industrial plants are completely considered in the model. The effects of sources are inspected on the adjacent marine environment. The numerical model is developed using finite difference method in two horizontal dimensions in plane. The model is applied in several planes along the depth and the effect of depth variation is considered in a depth integrated manner. The pattern of pollution spreading in the water is accurately investigated in various conditions due to spring and neap tides. The various conditions of wind are also considered in the study including various direction and speed based on the available meteorological data. It was concluded that the locations of wastewater outfall and the discharge, temperature, velocity and direction of outfall jet are appropriate to satisfy all of the environmental rules.
