Learn about advanced geo-hydrologic modeling techniques for coastal barrier island management in this conference presentation focusing on Sapelo Island, Georgia. Explore how LiDAR-based elevation models, gSSURGO data, and NAIP landuse classification are utilized to analyze erosion patterns and watershed characteristics. Discover the implementation of ArcHydro software on ArcGIS Pro for micro-watershed delineation and stream network mapping, along with RUSLE model development for spatial soil erosion assessment. Examine the application of QSWAT-based hydrologic modeling to determine streamflow and sediment variations in barrier island environments. Gain insights into how these combined modeling approaches provide crucial decision support tools for environmental managers responsible for preserving and managing coastal barrier islands.
