AVSWAT (ArcView SWAT) is a complete
preprocessor, interface and post processor of the hydrological model
SWAT.
Without leaving the user friendly ArcView GIS environment the user is provided
of a complete set of tools for the watershed delineation, definition and
editing of the hydrological and agricultural management inputs, running and
calibration of the model. The extension and the model constitute a
comprehensive and user friendly tool for the watershed scale assessment and
control of the agricultural and urban sources of water pollution.
AVSWAT has been developed by Blackland Research Center,
a Texas Agricultural Experiment Station part of Texas A&M University System
in Temple, Texas, in collaboration with Grassland Soil and Water Research Lab
, a USDA-ARS laboratory in Temple, Texas.
AVSWAT is organized in several linked tools
grouped in the following eight components:
(1) Watershed Delineation; (2) Land Use and
Soil Definition; (3) Editing of the model Data Bases; (4) Definition of the Weather
Stations; (5) Input Parameterization and Editing; (6) Model Run; (7) Read and
Map-Chart Results; (8) Calibration tool;
AVSWAT has been developed as an extension of
ArcView GIS entirely in Avenue and dependent by Spatial Analyst and Dialog
Designer extensions. The Spatial Analyst functions are used within the
Watershed Delineation and Landuse and Soil Definition components while the
Dialog Designer controls have been used to build up all the user interface
tools.
