ACCURACY VERIFICATION OF A REAL-TIME PREDICTION SYSTEM FOR WAVE RUNUP HEIGHTS

A real-time wave runup heights prediction system for about 500 coastal points in Japan was developed to take precautions and evacuate from flooding caused by wave overtopping. Accuracy verification of the system for recent wave overtopping events shows that actual conditions during the events can be adequately forecasted with the use of appropriate formulae on wave runup. The verification also indicates that the system can predict disaster risk from storm surges and high waves with enough time for flood prevention measures and evacuation.
