DEVELOPMENT OF WAVE OVERTOPPING AND WAVE RUNUP FORECASTING SYSTEM USING DEEP NEURAL NETWORK

Abstract

 In this study, we aimed at building a system which can forecast coastal distribution of wave overtopping and wave runup with the precision of block unit. At first, we performed a surge and wave simulation that can reproduce observation data at Suruga Beach. Then we constructed DNN model which can reproduce results of the simulation. We built the system to calculate wave overtopping and wave runup by IFORM using output of the DNN model and astronomical tide. We applied this system to the case of typhoon No. 19, 2019 and verified its validity
