Flooding disaster induced by the torrential rain of typhoons is one of the major natural disaster in Taiwan that causes the losses of people’s life and property. Recently, climate change is becoming more significant and the extreme weather events will frequently happen in the future. In order to minimize flooding disaster, Water Resources Agency (WRA) has completed inundation potential maps of Taiwan in recent years and announced these maps for public. Recently, inundation disaster often occurred in some Highland townships where are not in the simulation area because the elevation is less than 50 m. Therefore, the project will build a Highlands inundation model that can simulate subcritical, supercritical and transcritical flows to meet the hydraulic characteristics of the mountainous terrain changes, and the inundation potential maps of Highland townships are finally produced. In 2009, WRA has reached the goal of flood risk map and vulnerability map based on advance research, flood maps and the development of our country. Based on the contribution of &quot;a study of methodology for analyzing vulnerability and risk maps&quot; and &quot;The handbook of flood vulnerability and hazard map process&quot;, this project will build the flood hazard, vulnerability and risk maps of Tamsui River, Sulfur Creek, Lanyang Creek, Fengshan Creek, Touqian Creek, Zhonggang Creek, Houlong Creek, Yilan County, Keelung City, Taipei City, New Taipei City, Taoyuan County, Hsinchu County, Hsinchu City and Miaoli County. The results of this project could give more effective and practical information to governments for making correct decisions.高地淹水模擬模式脆弱度風險highlands inundation modelvulnerabilityrisk
