Abstract
The reduction effect of buildings for tsunami and storm surge in coastal area was verified with a hydraulic model test in a flat water basin.Water forces among the buildings and water levels and velocities at their backside were measured modifying their allocation of buildings in order to identify the causes of reduction of water level and velocity of wave run-up in the test. It was confirmed that the reduction effect by the allocation of building is varied according to the effect of energy loss by eddies generated around the buildings and the most effective one was a plover allocation pattern.Comparing the maximum run-up distance with the numbers of a regular allocation pattern, the reduction effect was confirmed at two lines in solitary wave and one line in long period wave.
