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

Numerical modeling is carried out to investigate the spreading pattern of industrial wastewater released fromcoastal refineries and power plant into the Persian Gulf. The pollutant sources due to the wastewater outfallof the coastal industrial plants are completely considered in the model. The effects of sources are inspectedon the adjacent marine environment. The numerical model is developed using finite difference method intwo horizontal dimensions in plane. The model is applied in several planes along the depth and the effect ofdepth variation is considered in a depth integrated manner. The pattern of pollution spreading in the water isaccurately investigated in various conditions due to spring and neap tides. The various conditions ofwind arealso 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 anddirection of outfall jet are appropriate to satisfy all ofthe environmental rules
