Available in PDF, EPUB and Kindle. Book excerpt: The threat of flooding is a serious concern to local governments. During a flood event, it is critical to have accurate estimates of where the flood is. Hydrologic models can serve as valuable tools in urban planning, especially in environmental planning. The Geographic Information System (GIS) technology has been used for storing, analyzing, and visualizing spatial information. By linking GIS, computerized hydrologic model, and expert knowledge into a spatial decision support tool, this project is to assess flood hazard for different land-use scenarios for a range of rainfall events in the Mill Creek Watershed. This study investigated the effect of urbanization and agricultural development on runoff. By comparing land use in 1980 and 1992, runoff was calculated and flood areas were delineated using the runoff curve number method. The comparison study showed that both urbanization and agricultural development result in an increase in surface storm water runoff and greater flood area.
