Abstract

In this research, a mathematical model is used to simulate the pollution
in the reservoir. The hydrodynamic model that provides the velocity field and
elevation of the water. The dispersion model gives the pollutant concentration as a water quality measurement. The reservoir is connected to the outer water area is considered. In the simulating processes, we combined the Galerkin finite element method and the finite difference method to the system of hydrodynamic model. At each time step the calculated velocity of the hydrodynamic model are input to the second model as field data. The case study in simulation of the current and the pollutant concentration in the open reservoir are presented.
