Short summary
A numerical model was developed to simulate tsunami run-up in a densely built-up area by introducing internal hydraulic conditions on building footprints. Computation showed good agreements with observation on maximum wave heights and wavefront speed in streets in the 2011 Tohoku tsunami. An indicator for tsunami impact was introduced based on observed distribution of washed-out houses, and a numerical experiment suggested that building array improvement would reduce damage of houses remarkably.
