![]() Infill rate of the bar after sand dredging is also discussed in term of average absolute sediment transport rate. After sand dredging in all cases, the beach profiles were not translated to the same original form. The final shoreline retreat in the last two methods was nearly equal to the first method, however, the progress of shoreline retreat was slower. periodic sand dredging method under the same regular wave condition as well as one time dredging under different regular wave conditions. The beach nourishment project permits require that the sand placed be loose enough to ensure suitable nesting habitat for sea turtles. In the other considerations, sand bar was dredged as different methods i.e. The Santa Cruz Port District dredges the harbor channel between November 1 and May 1 of each year. The results showed that the relationship between shoreline retreat and dredging volume is nonlinear. Beach communities and environmentalists are pushing back against a proposal to give the National Park Service the option of using dredging. The stockpile serves as a sand source for beaches farther east and is replenished at 2- to 3-yr intervals by a hydraulic pipeline dredge performing navigational. The effect of sand dredging volume on shoreline retreat was investigated by dredging various amounts of sand at one time under the same regular wave condition. Army Corps of Engineers to determine the feasibility of rehabilitating ocean beaches by employing hopper dredges. A wider beach ensures a protected and sustained natural environment for the sea turtles and sea birds that make their homes or nest on our beaches. To evaluate the relationship among the volume of sand dredging, method of sand dredging, time of sand dredging, shoreline retreat and evolution of beach profile, some experiments were conducted and a two-dimensional numerical model was used. A wider beach provides extended storm protection in Horry County for more than 3.7 billion of oceanfront residential and business properties. ![]() The sand dredging activities may cause various physical and environmental changes such as beach erosion, evolution of beach profile, change in current and wave field. ![]()
