Abstract

The purpose of this study is to investigate the characteristics of sediment transport by secondary current of the first kind in a closed water area, and to obtain basic knowledge for constructing an efficient sediment accumulation method in shurinp farms. Two hydraulic experiments were conducted. In the experiment 1, the sediment behavior was examined by changing the flow rate. In the experiment 2, the sediment behavior was examined by repeatedly discharging and stopping the pump. The results showed that the secondary current of the first kind becomes stronger after the pump is stopped. The momentary large traction force at the startup of the pump significantly affects the sediment transport, and the deposition area. We also conducted the threedimentional computer simulation in the same conditions with the experiment is shown that the fundamental aspects of the phenomena were succesfully reproduced by the present computational model.
