MODFLOW-NWT groundwater-flow models used to delineate areas contributing recharge to selected production wells in unconfined and confined glacial valley-fill aquifers in Chenango River Basin, New York
In the Chenango River Basin, New York, glacial valley-fill unconfined and confined aquifers 
are an important source of drinking-water supplies. The U.S. Geological Survey developed 
three-dimensional groundwater-flow models (MODFLOW-NWT code) of three study areas 
in the basin to improve understanding of groundwater …
