Nonpoint Source Pollution Modeling (with GIS)

摘要: Pollution modeling in this chapter refers primarily to the of nonpoint pollution surface runoff. This type is commonly denoted as hydrologic and water quality (HWQ) modeling. A good HWQ model must have a its foundation. models incorporate hydrology parameters. They are used describe occurrence movement water, nutrients, pesticides other materials through system. Most require large amounts spatially referenced input data. geographic information system (GIS) an excellent way managing these Further GIS can be display results manner that understandable by lay person. Results prepared wide array graphical formats enabling one better visualize predictions. details efforts with source United States. There are, however, significant advances being made outside U.S.
