近年來，臺灣地區受氣候變遷影響產生的坡地災害勝於往常，如2009年莫拉克風災，人口密集處受災的社會成本與人民生命財產損失龐大。配合國科會「國家科學技術發展計晝（102〜105年）（草案)」，爰加強坡地社區災害評估模型之建立及調適策略之研發。本研究以坡面尺度為例，建立極端降雨引致坡地災害之廣域評估模式，評估坡地因極端降雨誘發山崩及土石流災情之區域，研擬坡地社區安全管理策略與工程減災方案。然目前坡地災害（係指崩塌與土石流)相關研究，分析與模擬方法大多僅針對單一災害，鮮少有結合崩塌與土石流模式，且多數模式僅適用於單一溪流或場址，少有整合模式能應用於集水區尺度。有鑑於此，本研究將應用現行崩塌、土石流模式理論，整合邊坡穩定計算及土石流動態模擬等技術，研擬整合坡地災害潛勢評估方法。In Taiwan, slopeland disasters have increased in recent years because of climate change. The effect was especially apparent during Typhoon Morakot of 2009. The impact would be great if heavily populated areas were hit and loss of life and property damage resulted. This project aims to develop a hazard assessment model and adaptation strategy for hillside communities under the guidelines of “The National Science and Technology Development Plan (2013-2016)” of the National Science Council. This project would establish (1) an assessment model for slopeland related hazards under an extreme rainfall scenario; (2) identification of areas with landslide or debris flows which could be triggered by extreme rainfall; (3) a proposals for the management strategy and mitigation options for hillside communities on a slope scale. Current research related to landslide and debris flow mostly focuses on a single hazard type, and the scale of analysis is limited to small catchments or a single site rather than being done on a larger scale. Hence this project would integrate present models of landslide and debris flow, together with slope stability analysis and debris flow simulation techniques to conduct a hazard assessment of hillside communities.
