Flooding is a widely recognized problem throughout coastal South Carolina. The goal of this project is to provide, through the use of a map-based tool, site-specific information on stormwater runoff and tidally-driven inundation to areas in coastal zones where these two processes exhibit (or have the potential for) compound flooding risk (CFR).
Using existing data from previous studies and future sea level rise forecasts, the purpose of this project is to create a user-friendly, map-based tool to estimate CFR for a particular property of interest based on watershed (land use and land cover, soils, antecedent moisture condition) and the receiving water body conditions for storm events of different amounts and intensities. The results will be useful for stakeholders assessing compound flooding hazard, and will also be useful at the regional scale by improving conceptual models of stormwater runoff and tidal flooding.
