The hydraulic model experiment is used often to make the design of Sabo works. But reports to confirm the reliability of the hydraulic model experiment are not so much. Because the plan flood occurrence is rare in the field.<br>In this report, the hyetograph and the maximum rainfall in September 15-16, 1998 at Uono river were compared with the plan. And the peak discharge during this flood was guessed by the maximum rainfall and the catchment area around Uono river. Those were shown to almost equal the plan from this study.<br>The hyerograph was guessed from data of water level on Oogawara gaging station at the confluence of Daigenta river and Uono river during this flood. And the disaster occurrence time and location during this flood were compared with the experiment results under the same arrangement condition of Sabo facilities. The trend of those coincided with the experiment results.<br>We compared the flood scale and flood situation of field with the plan flood and the experiment results. Those in the field almost equaled the plan and the experiment. And it was shown that the hydraulic model experiment was useful to make the design of Sabo works from this report.
