Abstract
Sandbank-lagoons are generally natural harbors for their good defense of wave, deep water near the coast and little source of sediments. Taking Bohe harbor locating on the sandbank-lagoon in South China as the example, water-sediment regime in the harbor block has been studied in this paper. It is shown that wave-induced long-shore current has a significant impact on the sediment movements in the planned harbor block and its back-silting is controlled by SW flow and wave power, and the training dike can trap sediment into the harbor block. And so in the harbor block planned around the west side of Bohe bay mouth not only can shelter the entrance of the lagoon and control wave-induced long-shore current, but also improve environment for back-silting.
