Among existing methods for inundation modeling, some methods are accurate to model buildings, but costly in term of computational time while other methods require lower computational costs but constructed area may not be modeled well. The objectives of the present study are thus to compare two methods in resolving inundation area on tsunami numerical simulations and combine them to propose tsunami simulation system using FVCOM considering the fine structure of land use in unstructured grid model. Validation of the developed system comparing to experimental cases has been conducted for tsunami inundation modeling in constructed environments. General magnitudes of idealized model are reproduced well using the proposed system. The system has also been applied to simulate a Keicho-type tsunami in Yokohama in Tokyo Bay to show their differences.
