中文摘要 | 荖濃溪為高屏溪主要支流之一,莫拉克颱風(Morakot)為2009年編號第8號之颱風,莫拉克颱風於本地區超過3000mm之雨量,最大時雨量超過100mm/hr,造成本溪流域內嚴重坡地災害。由初步災害調查中顯示,莫拉克颱風帶來之鉅量累積雨量且長時間連續強降雨特性,對荖濃溪之嚴重的崩塌及土石流災害與有顯著之影響;除豪雨外造成災害之因素,尚包括:迎風面、順向坡構造、居住於堆積扇、緊鄰山坡缺乏緩衝空間、崩塌擠壓造成河流擺盪、及嚴重土石流因素等,交織成變臉的荖濃溪。 |
英文摘要 | Lawnon River, the major branch of Kaoping River, was damaged by Typhoon Morakot which inducing the accumulation precipitation more than 3000mm and up to 100 mm/hr in intensity. A reconnaissance was conducted shown the severe slope failure and debris flows of Lawnon basin were related to the huge rain accumulation and long duration of intense precipitation by the typhoon. Besides, the topography and geology are enhanced the hazard of disaster, such as slope aspect in windward sides, dip slope topography, residents lived in deposition fan, lacked of buffer zone, river swing caused by dammed, and severe debris flow, inducing a face-off of basin environment. |
