Erosion is a substantial problem on many shorelines of the Galveston Bay complex, as well as other bays of the Gulf of Mexico. Erosion can be prevented by structural measures such as riprap and bulkheads, but shoreline structures often replace the marsh habitat that is important to various estuarine species. Bioengineering, which is the use of vegetation in combination with various low-cost building materials, can often be established to prevent erosion and is less costly than traditional methods of shore protection. Additionally, bioengineering methods with marsh vegetation often offer a more diverse and more species-rich habitat than use of traditional structures alone. This paper discusses some wave break devices, erosion control mats, and other methods in combination with smooth cordgrass (Spartina alterniflora) that were tested at a dredged material site, Bolivar Peninsula, Galveston Bay, Texas
