AGNPS

Agricultural Non-Point Source (AGNPS) Pollution Model

AGNPS is a land use and conservation model that simulates the effects of pollutant loading, nutrient cycling, sediment transport and evapotranspiration in agricultural watersheds.

Model Information
For more information about this model, go to www.nrcs.usda.gov
Spatial Resolution
The region of analysis is split into grid cells, where each cell has the same soil and topographic parameters.
Temporal Resolution
Time step is daily, but output can be aggregated to monthly.
Outputs
Outputs include water flows and temperatures, sediment movement behavior and nutrient loading.
Intended User
practitioner
Model Type
watershed
Inclusion of Climate Change
Model includes a daily climate input file, which could be representative climate change scenarios. Secondary climate files can be supplied for each cell to override climate data in the primary daily data set.
