ItemThe Ike Dike: a coastal barrier protecting the Houston/Galveston region from hurricane storm surge(2012-02) Merrell, William JPresentation by Dr. Merrell to the U.S. Army Corps of Engineers regarding the challenges, desirability and potential model of the Ike Dike at preventing damages from hurricane surges in the Houston/Galveston area. ItemThe Ike Dike: a coastal barrier protecting the Houston/Galveston region from hurricane storm surge(2012) Merrell, William JPresentation on the Ike dike including: what we wish to protect; the nature of the threat; proposed comprehensive solution; next steps. ItemThe Ike Dike: a coastal barrier protecting the Houston/Galveston region from hurricane storm surge; a presentation to the Board of Trustees, Galveston Wharves, September 27, 2012(2012-09) Merrell, William J.Presentation by Dr. Merrell to the Board of Trustees, Galveston Wharves, concerning the concept and reasoning behind creating an "Ike Dike" to protect the Houston/Galveston area from tidal surges resulting from tropical weather events.

Progress and status report May 15, 2006(Coastal Geology Laboratory, Texas A&M University at Galveston, 2006-05-15) Webster, Robert; Dellapenna, Timothy MThe beaches of Galveston Island experience an annual beach cast of Sargassum (“seaweed”) during late spring/early summer – a season of significant economic input to the island and county. This accumulation inspires much debate among numerous stakeholders including property owners, business owners, recreational fishers, tourists, and local, county and state governmental entities. Several management options have been suggested, but as yet, there is no holistic management program for the island. Many locations are raked or scraped (e,g. Pirates Beach), and other locations are left in the natural condition (Galveston Island State Park). At this time, there appears to be no scientific data regarding the impact of beach cast on the Gulf beaches of Galveston Island. There have been recent studies pertaining to these issues along the coast of Kenya Africa, Eastern Indonesia and Western Australia. The study in Kenya using surface studies found that raking of beach cast had substantial impacts on the beach stability thus increasing the possibility of beach erosion. In order to facilitate informed decision making regarding the management of the “sargassum issue”, the Coastal Geology Laboratory at Texas A&M University at Galveston is in the process of quantifying the influence of sargassum on beach morphology. This data will be of utility to the numerous stakeholders involved and the decision making and management of the island’s beaches. This study will take the above research a step further by pulling several one meter depth cores along specified sites four times per year with each core being analyzed for organic content and sand grain size The specified sites will have the beach profile measured on a monthly basis to help locate potential accretion areas for future coring. The collection of data from February thru April is essential in developing base line data that will be used for comparison to the data collected during September and November after the conclusion of the sargassum season. ItemTexas Delegation to the Netherlands September 16-18, 2012(2012-10-02) Merrell, William J.Delegation from Texas A&M University at Galveston and Galveston citizens and business owners goes to the Netherlands to see coastal barriers designed to facilitate tourism as well as protect from tital surges. The barriers are integrated into the landscape and provide protection from surge events from the North Sea. Of particular interest is the annual exercise in closing and reopening the gates at the Maeslant Barrier.
