AGRICULTURAL NONPOINT SOURCE POLLUTION (AGNPS)
Developed by the USDA Agricultural Research Service, Agricultural Nonpoint Source Pollution (AGNPS) model addresses concerns related to the potential impacts of point and nonpoint source pollution on surface and groundwater quality (Young et al., 1989). It was designed to quantitatively estimate pol...
