Abstract
<p> In this study, the accuracy of the inundation analytical model was evaluated by comparing the obtained results and actual values (inundation area, actual water level, and temporal changes of water level obtained from photos and video) on the inundation due to dike break of the Chikuma River in 2019. In addition, a 2-meter grid was used for the inundation analysis to represent the influence of buildings in the area near the dike break site. Comparison of the analysis results with and without buildings showed the importance of considering buildings in the inundation analysis.</p>
