A web-based decision support system (DSS) was developed to assist watershed hydrologic/water quality assessment for present and future land uses. The DSS was comprised of an integration of webbased programs, a hydrologic model, GIS and databases. The integrated DSS uses web-GIS capability for Internet map browsing, online web-based watershed delineation and hydrologic spatial data extraction for Long-Term Hydrologic Impact Assessment (L-THIA) application. Although watershed management includes complicated steps and the online DSS has restrictions due to the web environment, this web-based DSS system still has potential applicability in assisting with watershed management decisions.
