XBeach model setup and results for beach and dune enhancement scenarios on Galveston Island, Texas

XBeach, a coupled hydrodynamic/morphodynamic numerical model, simulates erosion and deposition caused by Hurricane Ike on a 2.6 km stretch of West Beach, Galveston Island, Texas. Hurricane Ike, which made landfall in September 2008, is used as an illustrative future strong hurricane. Three dune morphologies consistent with Galveston, Texas Code of Ordinances and the Coastal Engineering Manual were used as input to examine the protection afforded the island from washover and erosion. A beach nourishment profile was also incorporated into two of the dune profiles to assess its role in dissipating storm surge and wave energy. This dataset contains the set-up scripts, wave and tide/surge data, LiDAR-based digital elevation models (DEMs) for 2006 and 2008, experimental dune or dune and beach nourishment profiles, and the model output (bed level, sea surface height, wave height, water velocity, and net erosion).
