Water Quality Model Integration in a Decision Support System
This paper describes an integral system to model nonpoint source pollution in surface waters. Diffuse pollution models were included in a Spatial Decision Support System (SDSS) with a unique platform, common interfaces and Geographic Information System (GIS) capabilities. This consists of pre- and post-processing tools, model control and sensitivity analysis for the parameters in the models. Particularly, the construction of the interface for WATFLOOD (flood forecast hydrological model) and its link with the decision support system RAISON (Regional Analysis by Intelligent Systems On microcomputers) is presented. A water quality component was coupled to the model in order to deal with sediment and nutrient transport. Previous work with the AGNPS (Agricultural Non-Point Source) model is used for comparison with the results from the water quality component coupled to the WATFLOOD model.
