Analysis of nonpoint source pollution in an agricultural
watershed by AGNPS involves providing input
The basic databases required for the AVNPSM
include: soil database, digital elevation, land use/cover,
hydrography, climate, and crop management information.
A soil database such as state soil geographic data
base (STATSGO) is used to extract information on soil
texture, hydrologic group, and soil erodibility factor (K).
