Abstract

In the present study, an inverse model was used to identify the location and functions of the intensity of unknown point sources in the river. In this research, the inverse solution of The advection-dispersion equation is carried out using a mathematical approach. The main objectives of this model are to identify the location of the pollutant in the presence of several sources in the river without any prior information from the sources in the entire mathematical framework. The strength point of the inverse model is that, by measuring the concentration-time curve from a few points, the source location can be obtained with the highest accuracy. Also, after finding the source location in the river, the functions of the intensity of the pollutant sources are restored. Verification of the inverse model provided by numerous hypothetical examples. In hypothetical examples, the location and intensity functions of the pollutant sources were considered differently so that the efficiency of the method is observed in different forms of intensity functions. Since in real mode, Measurements have errors, Error percent added to data. Finally, the verification was done between the exact state and the results of the inverse model. In all cases, the results of the inverse model were accurately acceptable.
