Popis: The Typhoon Hagibis in 2019 with heavy rainfall caused large-scale inundated damage in the College of Engineering, Nihon University and its surrounding areas. We need to understand the inundation mechanism caused by Typhoon Hagibis 2019 since it is concerned about the possibility of heavy rain frequently in Japan in the future. This study proposes a simplified estimation method for inundation height based on the kinematic wave model. The estimation result was validated by the measurement results to conduct field surveys. As a result,the difference between the measured and estimated inundation height was –0.15±0.28 m which was reasonable considering the accuracy of the digital elevation model from the Geospatial Information Authority of Japan.
