摘要：To study the emission of environmental pollutants, including urban and industrial wastewater of Bandar Abbas, through Gorsuzan estuary to the coastal waters of Bandar Abbas, located in the northeastern part of the Persian Gulf, a three-dimensional hydrodynamic numerical model was developed. This is to predict the pattern of chemical pollutant emission. The governing equations of this model are rewritten in the spherical coordinate earth system with a vertical sigma array. In order to validate the model, nitrate and nitrite measurements were performed spectrophotometrically at six stations on the coastal water of Bandar Abbas for a period of one year. The simulations showed that these pollutants are mostly spread in the areas of fishery pier and between Haqqani pier and fishing pier. Nitrite and nitrate concentrations up to 6 km east and 5 km west of the Gorsozan estuaries’ joint to the Persian Gulf is more than 60%. These results are consistent with the concentrations measurements carried out for these two pollutants in the mentioned areas. The average values of nitrate concentration in the four measurement seasons in Khorgorsuzan, Fishery wharf, and Haqqani wharf are 18.9 mg/l, 14.95 mg/L and 9.32 mg/ L respectively. Besids the amount of nitrite in the above-mentioned stations are 4.7, 4.45 and 1.87 mg/l respectively.
