Acquiring Nearshore Bathymetric and Topographic Elevation Data as well as Aerial Imagery of the Texas Lower Coast

Summary

The project goal is to acquire highly accurate and spatially dense bathymetric and topographic elevation data and Color Infra-red (CIR) aerial imagery of South Padre Island (Port Mansfield to Rio Grande) to evaluate position and change rates of the shoreline, vegetation line, and dune line; map geomorphic units; provide beach-dune system volumetrics; and develop a preliminary sediment budget. The investigation will help the General Land Office (GLO) to provide bathymetric (assuming sea conditions permit adequate laser penetration) data to depth of closure seaward of beach-dune projects with critically eroding shorelines, and topographic data and aerial imagery to the landward extent of the beach-dune system.
