The numerical modelling capacities of the INOWAS platform are completely based on the MODFLOW family. Specifically, MODFLOW-2005 is currently implemented to solve the groundwater flow (see T03 Numerical groundwater flow modelling and optimization), MT3DMS to solve solute transport (see T03b. Solute transport (MT3DMS)) and SEAWAT to solve density-driven flow (see T03c. variable-density flow (SEAWAT)).
