Abstract
<p> Buildings would have an effect on the inundation process of storm surge at densely built-up areas. In this study, we constructed a numerical model with 2m-grid mesh considering building configuration and layout, and calculated three-dimensional storm surge inundations due to potential maximum typhoon. As a result, inundation process behind coastal structures was found to be strongly affected by building configuration. It was also confirmed that flow velocity on narrow roads between buildings becomes faster. Opening or closing condition of tide gates was revealed to have a strong impact on the spatial distribution of velocity. A three-dimensional inundation simulation of storm surge with building configuration and layout would provide useful information on the examination of hazard maps and evacuation planning.</p>
