Model Abbreviated Name:

WATERSHEDSS
Model Extended Name:

WATERSHEDSS
Model Overview/Abstract:
To adequately control nonpoint source pollution of a water resource, water quality managers must focus on minimizing the impacts of individual nonpoint source pollutants. The strategic choice and placement of best management practices (BMPs) in the watershed can successfully reduce the input of individual pollutants and may improve water quality. WATERSHEDSS (WATER, Soil, and Hydro- Environmental Decision Support System) was designed to help watershed managers and land treatment personnel identify their water quality problems and select appropriate best management practices.

WATERSHEDSS is comprised of three components:

  1. The watershed assessment and evaluation which includes a pollutant budget spreadsheet and an agricultural best management practice (BMP) database
  2. An educational component, containing detailed information and references on NPS pollutants and sources.
  3. An annotated bibliography of NPS literature

Problem Identification
WATERSHEDS was designed to help watershed managers and land treatment personnel identify their water quality problems and select appropriate best management practices.
Summary of Model Structure and Methods
The watershed assessment and evaluation part of WATERSHEDSS includes a hypertext expert-systems-like user interface, the agricultural BMP data base, and the pollutant budget spreadsheet.
Key Limitations to Model Scope
There is no numeric answer. WATERSHEDSS helps to determine the most appropriate conservation practices for the pollutant of concern.
