Taiwan Flood Inundation Characteristics and Response Strategies
Taiwan is located in the typhoon track zone of west Pacific Ocean and Asia monsoon region with high temperatures and rich rainfall. In the past twenty years, the events of extreme precipitation are significantly increased due to global climate change and rapid urbanization. Flood inundation is serious in many urban cities and thus causes casualties and financial loss. As facing flood-related disasters, our aim is to reduce the damage by combining engineering and non-engineering approaches. For the engineering approaches, the regional drainage and storm sewer systems primarily in low-lying terrain and urban planning areas should be improved to fulfill a certain level of protection standards against the flood caused by extreme precipitation. For the non-engineering approaches, four major works including the improvement of urban inundation modelling accuracy, the enhancement of pluvial flooding warning systems, the development of new regulations for urban flood prevention and resilience city strategies are proposed and discussed.
Groundwater Monitoring Network Plan in Taiwan
Beginning from 1992, the Water Resources Agency has actively promoted the project “Groundwater Monitoring Network Plan in Taiwan”. The agency is in charge of planning, supervising, and funding supports for this project. The Central Geological Survey of MOEA, along with many other research institutions has all participated in this project. The total budget for this project is about 6.4 billions NTD (approximate 186 millions USD). The scope of the project includes
• To establish the regional groundwater monitoring network system in Taiwan, to collect the long-term integrated information related to the hydrogeology, groundwater hydrology, and groundwater quality.
• To conduct the related investigations on groundwater hydrology and hydrogeology, to fully understand the characteristics of each groundwater flow regime, and to distinguish the geological and hydrological systems of each area.
• To construct a groundwater hydrological information database and the integrated information system (including the decision-making supporting system), to facilitate the utilization and sharing of groundwater related data.
• To enact and promulgate the principles for groundwater resources utilization and conservation.
