A basic study on the stimulation of the tidal exchange of an enclosed coastal pond by the configuration of the opening is presented. Tidal current is obtained by the usual ADI method in two-dimensional plane. Movement of water particles is calculated by the Eulerian-Lagrangian method. The characteristics of tidal exchange of a pond are evaluated by the remaining function which is defined by the ratio of the number of the remaining particles inside the pond at each period to the initial number of particles. The average residence times are calculated by integrating the remaining function of some pond opening configurations. Corresponding model tests to the numerical simulations are conducted in a tidal tank, where the movements of the floating balls are analyzed by the image processor. Advection patterns of the particles are discussed by comparing numerical simulations with experiments.
