| dc.description.abstract | In Taiwan, the debris flow and flood disasters potential area are all over the island, and extreme temperature and rainfall will exacerbate the frequency and scale of disasters. However, no studies or reports integrate Taiwan river engineering adaptation strategies. Therefore, the objective of this research is to find out the extreme weather impacts on Taiwan river engineering, and then integrate the adaptation strategies.
In this study, through literature search and expert interviews, the impact of river project caused by extreme weather events is divided into four issues- flood protection, sediment management, water resources management, coastal protection. This study limits the adaptation strategies’ scope in flood protection and sediment management issues. After categorized the strategies into lifecycle and Fuzzy Delphi screening, there are 14 strategies in planning and design phase, 3 strategies in the construction phase, and 12 strategies in the operational maintenance phase. The important strategies include “ natural stream planning and design”, “detention basin”, “increase Channel Cross-Section”, “land use control＂, ＂held a local description and enable people to establish a correct concept of disaster prevention”, “evacuation strategies”,＂ strengthen prevention and early warning, improved dissemination of information quality ＂,＂ update the water level warning and response mechanism”.
Nowadays, extreme weather event is unavoidable, so we have to be positive to face the extreme weather impacts. We should use both structural and nonstructural measures for river engineering. This study results show that comprehensive control and management is important, and we have to improve disaster warning. At the same time, in addition to construct river activities, rebuilding after disaster is also important.
