Modeling groundwater contamination
Web9 jun. 2024 · Groundwater modelling is a useful tool to forecast hydraulic heads, changes in groundwater levels and changes in concentrations such as in cases of pollutant plume evolution and evaluating of aquifer protection strategies. Also, modeling can be used to hindcast changes in concentrations. Web17 nov. 2024 · Transport of TDS has been investigated by using MT3DMS, which is a computer model for simulation of advection, dispersion and chemical reactions of soluble contaminants in three-dimensional groundwater flow systems [7, 8]. The groundwater velocity field has been computed from the flow model by assuming an effective porosity …
