This study introduces NPSDSS, an integrated decision support system, to simplify nonpoint source pollution (NSP) management in catchment areas. It provides effective recommendations for NSP control, aiding water resource managers.

Area of Science:

Environmental Science
Water Resource Management
Geographic Information Systems (GIS)

Background:

Nonpoint source pollution (NSP) poses significant challenges for water resource managers in developing effective catchment area management practices.
Existing methods for modelling NSP impacts are complex and hinder the implementation of practical management strategies.

Purpose of the Study:

To introduce an integrated decision support system (NPSDSS) designed to simplify the modelling and management of nonpoint source pollution.
To provide a user-friendly tool for water resource managers to develop effective NSP management practices.

Main Methods:

Development of the nonpoint source decision support system (NPSDSS) on a unique platform.
Integration of the IMPULSE (integrated model of nonpoint source pollution processes) model, a GIS toolbox, database, measure screening model, and expert system within NPSDSS.
