Reservoirs are expected to be protected against mega earthquake damages. The imediate collaption of reservoirs due to a large earthquake, the houses around the reservoir are estimated damage due to the same fluid power as the tsunami. Therefore, numerical analysis can be considered by an effective method for predicting damage. In this study, the flood analysis is conducted with reference to the damage example of a house collapsed by strong fluid force due to few data of reservoirs damage. Analyzes the hydrodynamic forces of the flood and suggests ways to use the results to determine house collapse.
