Coastal disasters such as tsunamis, storm surges, and high wind waves are natural disasters that can occur in any coastal area worldwide.  They happen when several natural conditions, such as earthquakes, typhoons, local topography, and social conditions, such as prior disaster experiences and preparedness, are combined as unfavorable circumstances for the coastal residents.  They can occur at various time intervals, from tsunamis, which occur once every hundred or thousand years, to storm surges and high wind waves, which occur somewhere in the world every year due to typhoon strikes.  They can be as extensive as the 2011 Tohoku earthquake tsunami or the 2004 Indian Ocean tsunami, which extended hundreds of kilometres along the coast, or as small-scale as the 2024 Noto Peninsula tsunami in the central part of Japan, where the tsunami inundated land in a narrow area of tens of kilometres.  The purpose of surveying coastal disasters worldwide is to analyse them and then recommend strategies for disaster mitigation from a local perspective, adapted to the actual conditions in each region.  As Japan has historically experienced many coastal disasters over the years since the beginning of history, it is also essential to organise this experience and contribute to disaster reduction worldwide.  In practice, the first step is to conduct post-disaster field surveys and collect the data numerically and descriptively.  In order to incorporate new findings into disaster mitigation methods, hydraulic model experiments are used to observe phenomena in more detail and to understand the physical processes.  The results are then incorporated into a numerical prediction model to reconstruct a more concrete image of the disaster.  By sharing these results with the local residents, it will finally be possible to construct rational disaster prevention structures and create evacuation plans tailored to the actual conditions of the region.

Prof. Xiaojing Lv is from Shanghai Jiao Tong University. She is deputy Director of Shanghai Urban Energy Society and deputy Secretary General of China Marine Engineering Committee. She engaged in hybrid intelligent systems of fuel cell/gas turbine, zero carbon Marine power systems, hydrogen energy production and utilization from the theoretical and experimental points. In past studies, She has developed a large number of high-precision mathematical models and software libraries (SOFC.MCFC, gas turbine, smart energy system, zero-emission ship power system, all-eclectic ship micro grid, intelligence controller based on NN, Fuzzy and combined Machine Learning, multiple fuel to H2, such as biomass, LNG, sea water, and NH3,), and the relative experimental platforms. As an independent PI, she has presided over 15 national and Shanghai municipal government projects,including the international co-projects, published more than 80 papers and 15 patents,co-edited 4 books. Also as an 20 members team leader in low-carbon smart energy system in the Smart Energy and Big Data Research Center in SJTU.
