Selecting Suitable MODFLOW Packages to Model Pond–Groundwater Relations Using a Regional Model
In large-scale regional models, used for the management of underground resources, it is quite common to find that relationships between the regional aquifer and small wetlands are not included. These models do not consider this connection because of the small amount of water involved, but they shoul...
