2 Flow model

MODFLOW
(Mc Donald et al.
1996) along with
nonreactive transport
models MT3DMS
(Zheng and Wang,
1999) and RT3D
(Clement et al., 1997)

RT3D and MT3D models can
simulate the groundwater
pollutant transport in
combination with the flow terms
derived from modular
groundwater flow model,

transport model to facilitate the
investigation of a large variety of
problems involving inorganic
and organic chemicals in
variably saturated media
