Adaptation Strategies for Large-Scale Landslides and Dammed Lake Disasters
大規模崩塌及堰塞湖災害調適策略

            Climate Change has increased severe rainfalls and the probability of the large-scale landslides in catchment areas. Thus, rolling adjustments are needed to update the current disaster prevention strategies. In particular, compound earth and sand disasters, which may be caused by large-scale collapses, will pose serious danger to the safety of life and damage property. Therefore, the Soil and Water Conservation Bureau has proposed a large-scale Climate Change collapse prevention and mitigation plan, with the main objectives of; strengthening the large-scale collapse crisis response capabilities, building smart disaster prevention systems in large-scale earth and sand disaster areas, assessing effectiveness of harnessing earth and sand disasters in large-scale earth and sand disaster areas, resource conservation surveys in large-scale earth and sand disaster areas, water and soil conservation management in large-scale earth and sand disaster areas, and disaster prevention information promotion and exchange in large-scale earth and sand disaster areas. Over the years, the NCKU Disaster Prevention Research Center has assisted in; the development of large-scale collapse demarcation methods, the mapping of large-scale collapse zones and the check on Disaster Prevention/Relief resources , assessment of vulnerabilities and risk management, the establishment of large-scale collapse monitoring systems, developing methods for estimating rainfall in a large-scale collapse, and establishing a response management value for issuing a large-scale early warning. The NCKU Disaster Prevention Research Center uses annual international seminars and expert advisory committees to invite experts on large-scale collapse prevention and control technologies from home and abroad to collaborate, and is committed to improving the technical ability for reducing large-scale collapses and disasters in Taiwan. In addition, the NCKU Disaster Prevention Research Center develops contingency management policies and standard procedures for response to landslide-dammed lakes, carries out education and training to strengthen resilience, collects and organizes landslide-dammed lake disaster contingency cases, and provides professional consultation and cooperation in the event of disasters.

            氣候變遷造成劇烈降雨增加,提高集水區大規模崩塌土砂災害的機率,需要滾動式調整更新現行的治山防災策略,尤其是大規模崩塌可能衍生的複合性土砂災害將對生命財產安全帶來嚴重危害,因此水土保持局提出氣候變遷下大規模崩塌防減災計劃,主要目標為完成大規模崩塌危機應變能力強化及大規模土砂災害區智慧防災體系建立、大規模土砂災害區治理成效評估及大規模土砂災害區資源保育調查、大規模土砂災害區水土保持管理、以及大規模土砂災害區防減災資訊推廣交流。

            成大防災中心多年來協助開發大規模崩塌劃設方法、劃設大規模崩塌區影響區及清查防救災資源、評估脆弱度及風險管理、建置大規模崩塌區監測系統、研擬大規模崩塌雨量推估方法、訂定大規模預警應變管理值等,並利用年度國際研討會及專家諮詢委員會,邀集國內外大規模崩塌災害防治技術專家,致力於提升國內大規模崩塌防減災技術能量。此外,另針對堰塞湖災害擬訂應變管理策略及標準程序、辦理教育訓練及演練強化應變能力、蒐集彙整堰塞湖災害應變案例,並於災害發生時提供專業諮詢與協力。
