| dc.description.abstract | The project purpose is to address coastal erosion for the protection of life and property on Galveston Island. Beach erosion between 8 Mile Road and 13 Mile Road risks homes and public infrastructure including roads, utilities, and communication networks. As such, this project would reduce coastal erosion damages and improve human life and safety. The study purpose is to determine whether beneficial use of dredged material is a cost-effective solution. The study scope is for placement of dredged material based on the sand quantity from the required operations and maintenance dredging of the Galveston Navigation Channel. The length of beach to be nourished is dependent on the quantity of dredged beach quality sand and the amount of sand required based on the existing and with plan beach profiles. Sand placement is to ameliorate the coastal erosion damages for a segment of the island’s developed area adjacent to the public beaches. | en_US |
