The cure against sloshing is a very important subject on disaster prevention. However, only a few tanks were made in consideration of sloshing. Low-cost methods of sloshing suppression are desired. The authors predicted that horizontal plates installed near surface in the liquid beside the tank wall are effective to suppress sloshing. Analytical simulation and experiments were performed about parallelepiped tanks. The collocation method is used for analytical simulations. The simulations and the experiments confirmed the prediction that horizontal baffles suppress sloshing. The horizontal baffle plates obstruct up and down motion of liquid near the tank walls. As a result, sloshing becomes small. In this case, damping is not main factor of sloshing suppression. It is guessed that horizontal baffle plates are effective to suppress sloshing also in other shaped tank than the parallelepiped.
