Geospatial Technology Application for Small Reservoir Design with Environmental-friendly Decision Support

Learn how geospatial technology can be applied to design environmentally conscious small reservoirs in this conference presentation from the Georgia Water Resources Conference. Explore a comprehensive modeling process developed for the Big Creek sub-watershed in Forsyth County, utilizing 1-meter digital elevation models from LiDAR data, USGS surface water flow information, USDA soil data, and PRISM precipitation data. Discover how ArcGIS Pro and ArcScene software were employed to create automated geospatial models for runoff calculations and 3D reservoir basin visualization. Follow the engineering-based approach that considers flood control, wetland protection, and wildlife conservation while calculating reservoir fill times and flooding boundaries. Master the use of CN-value based runoff calculations, Map Algebraic functions, and volumetric analysis techniques essential for designing water harvesting structures that balance environmental preservation with water resource management needs.
