Tsunami Force and Tsunami Resistant Structure

Course Description

Design formulas of tsunami force are introduced and some examples to computation of tsunami force are lectured. An experiment to evaluate the tsunami impulsive force is demonstrated during this the course. As tsunami resistant structures, breakwaters and tidal barriers are shown as well as greenbelt techniques. Additionally a new real-time tsunami warning system employing the GPS tsunami buoy is presented.
