The Texas Gulf coast is a complex system with numerous narrow inlets and broad back bays with intricate river and bayou networks. Due to its complex settings, the Texas coast is susceptible to extreme compound flooding due to fluvial, pluvial, and surge during hurricanes and tropical storms. The Texas coast is also one of the United States most dynamic regions in terms of population and economic growth. The objective of the Coastal Texas Study was to improve our capabilities to prepare for, resist, recover and adapt to extreme events. A “Multiple Lines of Defense” strategy was used in the Coastal Texas study to design cost-effective, environmentally friendly solutions that will reduce risks of storms impacting the coastal communities and restore important wildlife habitat at the same time. This paper specifically addresses the feasibility of nature-based solutions such as a dune-beach system along Galveston Island and Bolivar Peninsula to reduce storm surge impacts and shoreline recession. The numerical model SBEACH (Storm-Induced BEAch Change) has been used to simulate the cross-shore response of representative existing beach profiles and alternative configurations while exposed to RSLC and extreme storm events. Evaluation of alternatives is based on storm-induced performance and sediment budget requirements to identify improvements that optimize resiliency of the coastline to reduce vulnerability to infrastructures.
