SEDIMENT MANAGEMENT OPTIONS FOR GALVESTON ISLAND, TEXAS
Galveston Island is a major tourist and commercial center on the Gulf of Mexico at the mouth of Galveston Bay, Texas, USA. The shoreline along the Galveston Seawall regularly requires beach nourishment while the beach west of the Seawall has severely eroded. In order to protect the island and ensure it is available for generations to come, a 50-year sediment management plan was developed. A sediment budget using the Sediment Budget Analysis System was calculated and numerous alternatives were simulated with GenCade, a shoreline change and sand transport model. Finally, several alternatives ranging from no action to a comprehensive beach fill and backpassing system are presented as part of the sediment management plan.
