Abstract

A blueprint for simulating heavy metal transport in soil under dynamic acidic conditions R.W. Al-Soufi Laboratory of Hydrology & Water Resources Management, Helsinki University of Technology, Konemiehentie 2, SF-02150 Espoo, Finland ABSTRACT A blueprint is presented for simulating long-term heavy metals transport through clay barriers. The calculation methodology is based on 3-dimensional advection-dispersion model. Modelling the adsorption-desorption process is based on the fact that more ions are retained by soil matrix during the adsorption phase than the amount released during the desorption phase. The model calculates the amount of ions remains in soil solution under dynamic acidic conditions. Among several applications, the model can be used to determine the optimum thickness of clay liner which ensures a secured place for the soluble heavy metals over a long period of time.
