In this study, hydraulic model experiments were conducted in order to understand the characteristics of suspended sediment transport due to tsunami at a water intake facility. Tsunami and suspended sediment flowed into the facility by opening a gate installed at the end of a reservoir. Sea area and the water intake facility, which consists of an intake tunnel and a pump room, were set up in an experimental equipment. The concentration of suspended sediment transported by tsunami inflow and water intake due to a pump was measured using turbidimeters.
It was confirmed that the water intake has a strong effect on flow field in the tunnel and pump room. The time-averaged and maximum concentration distributions of suspended sediment from the water inlet to the water tunnel to the pump room were also found to be greatly influenced by the intake flow rate.
