NOURISHMENT OF SAN LUIS BEACH, GALVESTON ISLAND, TX: AN ASSESSMENT OF THE IMPACT. Conference Paper uri icon

abstract

  • One proposal to combat shoreline retreat and protect the foot of the Galveston Seawall is to build a wide beach by nourishing the entire beach in front of the Seawall. A small-scale nourishment project was initiated in the spring of 1985 along a 458 m section of the Seawall. The project has been monitored through November of 1986. The beach was nourished with 11,460 m**3 of material that ranged in grain size from 0. 08-0. 15 mm. The native beach grain size ranged from 0. 10-0. 42 mm. During the 17 months of monitoring, the shoreline retreated approximately 53 m and lost approximately 16% of the material comprising the beach after the nourishment was completed. Beach material was found to have exited the system via the following pathways: 1) suspension and subsequent movement offshore, 2) end loss, 3) profile adjustment, and 4) aeolian transport.
