Numerical Simulation of Pollutant Dispersion in Surface Water Resources

The main objective of this study is to develop a higher order numerical scheme to simulate the pollutant spreading in surface water resources. The new discretisation schemes in Finite Difference Method are presented in one and two dimensional domain to predict surface water quality. Moreover, the effect of dimensionless computational numbers on numerical processing and errors is investigated for several methods. The grid size sensitivity analysis is made based on numerical results which are obtained in several methods. A real case study is made for thermal pollutant released from cooling water outfall of a power plant into the adjacent river. The numerical results are compared with field measurements and a good agreement is obtained.
