The Ninoarate weir having a broad crest and three culverts is located at a junction between the Asahi River and the beginning of the Hyakken River. This weir was severely damaged due to local scour under flood flows on October 18^<th>, 1998. This paper deals with the numerical analysis of the local scour occurring downstream of the broad crested weir with culverts on the bottom. In order to clarify the mechanism of the local scour that occurred downstream of the Ninoarate, which has a broad crest and three culverts in the low water course, 2-D numerical simulations using a boundary fitted coordinate system were developed based on the results of experiments and field surveys and applied to the experiments under the flood condition. Comparing the numerical results with the experimental ones verified the ability of this model to predict the channel process.
