Modeling of propagation and propagation of oil pollution during fashion in the rivers of Arvandrood

In this paper, modeling the distribution of oil pollution in Arvandrood using the Mike 21 model has been studied. In this study, the distances of the networks are considered with the accuracy and volume of 70 × 70 m calculations, 1345 nodes in the horizontal direction and 1574 nodes in the vertical direction and at a time interval of 60 seconds, and finally the depth file is constructed. The bottom line of the time series is the time of the change in the level of water level and applied to the upper boundary of the water level changes in the form of constant numbers applied to the boundaries. After calibration, the comparison of the model results with field measurements indicates that model has acceptable accuracy in predicting the fluctuation water level, side and flow velocity. To simulate the pattern of oil emission, the output of the hydrodynamic module is applied to the oil leakage analysis module. Modeling results show that if pollution occurs at the beginning of the fashion for 3 hours in front of the Abadan Oil Refinery and the average river flow rate is / s3 m480, without wind application, pollution reaches the Persian Gulf after 130 hours
