When danger of a tsunami is predicted, the flap stands up in a couple of minutes to protect coast inhabitant area from Tsunami invasion. In this paper, we discuss two-dimensional hydraulic model tests in a flume tank using a bore wave generator to confirm the wave pressure and gate behavior required for flap gate design. In addition, hydraulic characteristics due to tsunami were simulated using the VOF method to compare the results of the model tests. The results of numerical analysis generally tracked the results obtained in the model tests. However the wave pressure in numerical analysis did not agree with the results of the model tests in wave breaking condition. Three dimensional FEM by Flow 3D also simulated run-up behavior of Tsunami at a port area where the flap gate was installed at a mouth of the port. Through the test and calculation, flap gate for Tsunami is efficient for Tsunami invasion to port inhabitant area.
