REDUCING SHOALING IN THE TEXAS GIWW AND EROSION OF BARRIER ISLANDS ALONG WEST GALVESTON BAY

This project utilised a Regional Sediment Management (RSM) approach in an attempt to quantify the source of sediments, develop a conceptual design and associated cost estimation for remediation techniques to allow for the continued maintenance dredging of this portion of the Texas Gulf Intracoastal Waterway (GIWW). The erosion of the thin string of upland placement areas sheltering the GIWW from Galveston Bay is contributing to the shoaling rate; however the presence of these islands is reducing the amount of sediment load the channel would otherwise be experiencing.
