2018 HYDRUS Package for MODFLOW
The HYDRUS package for MODFLOW was updated in 2018 (Beegum et al., 2018ab) by additionally also including solute transport into the package and linking it to the three-dimensional groundwater solute transport model MT3DMS. The new package can simulate, in addition to water flow in the vadose zone, also solute transport involving many biogeochemical processes and reactions, including first-order degradation, volatilization, linear or nonlinear sorption, one-site kinetic sorption, two-site sorption, and two-kinetic sites sorption. Due to complex interactions at the groundwater table, certain modifications of the pressure head (compared to the original coupling) and solute concentration profiles were incorporated into the modified HYDRUS package.
