Abstract
The authors are now developing a new simulation system for tidal flow on a double closed bay, Omura Bay, which can simulate transitional flow by using actual tide in the bay. The system is able to perform tidal simulation with calculating optimum boundary condition by automatic control system, so it realizes that any sea area without tidal harmonic constant can be treated with the open boundary. In this paper they also tried the performance test resulting in that a tide of outcome from the system is the same as a tide of input.
