Evaluation of Beach Nourishment Opportunities with Dredged Material: Galveston Harbor
There is a potential to use material routinely dredged from the Galveston Ship Channel to nourish the nearby beaches of Galveston Island. The channel is dredged on the average every 2 years, removing over 1 million cubic yards of material from the inner bar, out bar, and entrance channels. Maintenance dredging has been accomplished by hopper dredging, however cutterhead dredging may be accomplished in the inner and possibly outer bar channels. Several factors will be important for a successful beach nourishment from any dredging project. They include; compatibility of the borrow material with the native beach, quality of material (color, texture, specific gravity, etc.). quantity of material and the pumping distance which directly effect costs.
