AN INTERACTWE MODELING ENVIRONMENT FOR NON‐POINT SOURCE POLLUTION CONTROL1

Abstract: Non-point source pollution cuntinues to be an important environmental and water quality management problem. For the moat part, analysis of non-point souree pollution in watersheds has depended on the use of distributed models to identify potential problem areas and to assess the effectiveness of alternative management practices. To effectively use these models for watershed water quality management, users depend on integrated geographic information systems (GIS)-based interfaces for input/output data managemen… Show more

“…Loose coupling methods usually involve data exchange. An interface program is normally used to convert and organize GIS data into a format required by the model (Liao and Tim, 1997). Close coupling passes information between the GIS and the model via memory-resident data models rather than external files, leading to improved model interactions and performance (Di Luzio et al, 2004).…”

“…Tightly coupled model integration focuses on incorporating the functional components of one system within the other (i.e. the model within the GIS program) (Liao and Tim, 1997). In this study, the CART has been integrated into ArcGIS using ArcObjects and Visual Basic for Application (VBA) to predict the spatial distribution of soil heavy metals contents.…”

“…For both loose and close coupling approaches, GIS-based approach can be dependent on selected GIS software for manipulating spatial data. For example, a number of GIS-AGNPS interfaces including GRASS-AGNPS (He et al, 1993;Line et al, 1997;Srinivasan and Engel, 1994), Arc/ Info-AGNPS (Liao and Tim, 1997), and Arc/View-AGNPS (He et al, 2001) have been developed for the same model, AGNPS, according to the popular GIS software's such as GRASS, Arc/Info, and Arc/View. Several spatial data manipulation procedures, including watershed and channel network delineation, can be commonly used for different hydrologic models.…”

“…Based on their research, other scholars used and improved the model for water quality forecasting (Guo et al, 2002). The second stage was from 1980 to 1995, involved the use of water quality models in more complicated systems and in combination with the watershed models, thus allowing non-point pollution sources to be treated as initial inputs (Liao and Tim, 1997). The third stage was from 1995 to the present during which the water quality models were developed into a comprehensive model from reaction models.…”
