MODFLOW-NWT groundwater flow model and GWM-VI optimization code for the Little Plover River Basin in Wisconsin's Central Sand Plain

The Little Plover River groundwater flow model simulates three-dimensional groundwater movement in and around Wisconsin’s Little Plover River basin under steady-state and transient conditions. The groundwater flow model uses the U.S. Geological Survey’s MODFLOW-NWT modeling code. This model explicitly includes all high-capacity wells in the model domain and simulates seasonal variations in recharge and well pumping. The model represents the Little Plover River, and other significant streams and drainage ditches in the model domain, as fully connected to the groundwater system, computes stream base flow resulting from groundwater discharge, and routes the flow along the stream channel. A separate soil-water-balance (SWB) model was used [...]
