Volume Title



Galveston Island is an eroding sand-starved barrier island located 50 miles southeast of Houston along the upper Texas coast approximately 60 miles from the Louisiana state line, at 29°18'17" latitude and 94º46'30" longitude. This proposed Innovative Technology Seaweed Prototype Dune Project would be implemented in the Apffel Park area on Galveston Island adjacent to the South Jetty. The proposed project area is accreting rapidly, and was one of the factors leading to its selection as the potential project site. Additional site benefits allow the demonstration project the opportunity to be monitored without being subject to immediate wave impacts. Erosion rates range from approximately -5.0m/yr west of the seawall to accretional areas of +10m/yr. per BEG. The majority of Galveston Island is eroding. Project proposes to utilize naturally occurring seaweed that washes ashore and utilize equipment to convert the seaweed into bales.
