However, since extraordinary danger exists in the observation during flood and the scale of the phenomenon is large, the observation of the breach have been conducted after the flood. In order to clarify the phenomenon on breach of flood levee, a small-scale hydraulic model experiment needs to be carried out. In this research, we tried to reproduce the result of the actual size hydraulics model test on the breach using the small-scale hydraulic model experiment in which the scale was changed. As a result, in order to grasp a phenomenon correctly in a small-scale hydraulic model experiment, it was shown that it is necessary to coincide the square of the ratio of critical friction velocity with a model scale.}, pages = {I_1123--I_1128}, title = {縮尺の違いによる越流破堤実験の再現性の検討}, volume = {68}, year = {2012} }
