| Summary | Both the South Asia Tsunami in 2004 and the huge Eastern Japan Tsunami in 2011 remind us how devastating a tsunami can be. For the purpose of hazard mitigation, a tsunami forecast system has been developed so that the wave height and the arrival time can be calculated in a very short time once a tsunami is generated. However, in the existing system, only the offshore tsunami height is provided; there is no tsunami information inside the harbor and hence no emergency management guideline for harbor companies. For both ordinary citizen and personnel in the administration agency, visualized inundation maps under a GIS system are very useful for people to easily acquire tsunami information inside the harbor and hence are useful for hazard mitigation. Therefore, this project will extend the existing system to include pre-computed inundation maps under a Google Earth GIS. This system will be integrated and executed by a Matlab graphic utility interface (GUI).
A tropical cyclone can induce huge damage in the coastal area. For example, although typhoon Haiyan was far away, 8 people were injured and 8 people were killed due to the induced coastal freak wave in Longdong Cape in 2013. Another example in 2008 is the storm surge due to the devastating Cyclone Nargis that caused widespread destruction in Myanmar. Typhoon-induced storm surges and swells are also hazardous to transportation systems, especially for bridges near a river mouth: in addition to the raised water level, storm surges and swells together can reach the deck and endanger people on the bridge. In this project, shallow water equations will be used to evaluate the water level in typhoon based on the flow rate provided by WRA and the surge height and swell height provided by IHMT. The results will be used for safety management of bridges. |
