Research Abstract	In coastal farmlands, reduction of the height of coastal levees by subsidence degrades their performance. Furthermore, in addition to the sea level rise, increasingly severe floods and typhoons are forecasted as a result of climate change. Consequently, the risk of flood damage caused by floods or storm surges is growing on coastal farmlands. Whereas the risk of storm surge disaster has been evaluated by numerical analysis, it is difficult to reduce flood damage by performing only risk assessments. Thus, effective measures to reduce damage on coastal farmlands are required. Through this study, I developed the self-standing type auxiliary embankment to prevent flooding by small or medium-sized storm surges, and verified its features by hydraulic model experiments.
