This study examined the structure of Water-Intake-Works, which can control the inflow of suspended sediment to the inside the fishing port without reducing the amount of introduced water. A section experiment on two dimensions and a numerical calculation were executed in this study. As a result, it is confirmed that reducing the suspended load and controlling the vortex generated in water chamber could reduce the inflow of the suspended sediment to the inside the fishing port. The results also showed that there were several effective methods to reduce the suspended sediment in inflow as following: 1) to enlarge the size of the submerged mound and water chamber, 2) to install the rejection sand entrance, 3) to install the partition wall in water chamber, 4) to make training mouth upward.
