A New Approach for Modeling Dissolved Lead Using an Integrated 1D and 2D Model

A. Roshanfekr, S.M. Kashefipour and N. Jafarzadeh

In the present research, the dissolved lead is modeled using a linked 1D and 2D hydro-environmental model. Details are given for the governing equations and solution methods used in these numerical models, together with a discussion of a new development in dissolved heavy metals modeling using varied reaction coefficients in the model. It is found that pH and EC play an essential role in adsorption and desorption of heavy metals by the particles in solution. Therefore, in this study it has been tried to find the best relationship between pH and EC with the reaction coefficient. Relatively close agreement between predicted results and field measured dissolved lead concentrations were obtained for different varied reaction coefficients using the linked 1 and 2D model. Finally, the best relationships for the reaction coefficients for dissolved lead were introduced and the results were successfully compared with the corresponding measured values.
