AGricultural Non-Point Source Pollution Model (AGNPS)
is a joint USDA - Agricultural Research
Service (ARS) and - Natural Resources
Conservation Service system of computer models developed to predict non point
source pollutant loadings within agricultural watersheds. It contains a
continuous simulation surface runoff model designed to assist with determining
BMPs, the setting of TMDLs, and for risk & cost/benefit analyses.
The set of
computer programs consist of: (1) input generation & editing as well as
associated databases; (2) the "annualized" science &
technology pollutant loading model for agricultural-related watersheds
(AnnAGNPS);
(3) output reformatting & analysis; and (4) the integration
of more comprehensive routines
(CCHE1D)
for the stream network processes;
(5) a stream corridor model
(CONCEPTS); (6) an instream water
temperature model
(SNTEMP); and (7) several related salmonid models
(SIDO,
Fry Emergence, Salmonid Total Life Stage, & Salmonid Economics). Not all of
the models are electronically linked but there are paths of common input/output
that, with the use of standard text editors, can be linked.
Summaries of the capabilities of the components of
AGNPS are provided through the menu links on the index page. More detailed descriptions
of the components, with example datasets, and the programs can be found at the AGNPS download page.
Many individuals have cooperated in the development of
AGNPS and they can be found in the Personnel section under the
Project Team. Many users have also registered as Cooperators who
are using the model or working with AGNPS and are provided support
by the AGNPS team. Users are invited to register at the download
page where individuals can see others that are using the model that
might be a basis for further cooperation.
