Numerical Simulation of Solute Transport in Groundwater Flow System Using Random Walk Method

Abstract

This paper presents the new random walk solute transport model (RWSOLUTE) for solute transport simulation in groundwater flow system. This model is novel in using an efficient particle tracking algorithm. The proposed model is validated against analytical and other reported numerical solutions for chosen test case. The accuracy and stability of the RWSOLUTE model solutions are verified through mass balance error checks and Courant stability criteria. Further the sensitivity of the model solutions is analyzed for varying values of time step size and particle mass.
