3. Modeling and forecasting plume evolution
3.1 Modeling objectives
Numerical modelling meets a first objective: to explain certain more or less complex mechanisms. The model can be used to determine the variation in pollutant concentrations as a function of time, the volume of the polluted aquifer, the rate of pollutant migration, the time it takes to reach potential targets and the possible risk to these targets
