    The study provides longitudinal and cross-sectional analysis of 8 pieces topography data collected from 1980 to 2011 and bed material particle size based on three investigations conducted between 2008 and 2012. The mainstream topography data in December 2007 shows that the head-cutting distance was about 3 kilometers after the dam broke. The topography data since 2008 displays that river the channel is stable as well. The topography data shows that the longitudinal section in the tributary had a head-cutting distance of about 3 kilometers after the dam broke, and the river channel still is showing adjustment behavior. The scour-and-fill analysis result of the mainstream cross-section shows that the transverse adjust changed significantly upstream from the dam location from 2006-2008. The particle size of the bed material has shown a trend from coarsening to fining according to different sampling points. Therefore, the river bed is still adjusting continuously. Finally, this study is based on a debris flow and sediment laden flow numerical model. The simulation result is fit for river-bed changes after dam-break.2007年石門水庫上游的巴陵防砂壩潰壩事件,導致上游河床沖刷約20公尺,下游最大淤積約10公尺。本文蒐集巴陵防砂壩1980至2011年潰壩前後8次地形測量資料與2008-2012年共進行三次河床質粒徑調查以分析潰壩對於河床變動及河床質粒徑變化的影響。結果顯示,巴陵壩潰壩3個月後河床已逐漸趨於動態平衡,河床質粒徑整體有粗化再細化的趨勢。最後,本文以適用於土石流及高含砂水流的數值模式進行潰壩事件模擬,並利用河床測量成果進行比較

    [[abstract]]環境保護的議題在近年來臺灣經濟發展的過程中受到極大的關注,也是許多企業面臨的問題。有機農業、有機食品、無公害食品之產業也伴隨著國民所得的增加而發展,有機專賣店的興起更代表著綠色產業在零售流通業中已逐漸開始佔有一席之地。企業在無前例可循之下,如何利用有限的資源達到顧客需求是極為重要的。如果能將綠色行銷的品質要素加以分類,使企業可以快速發現那些要素應當最先受到重視,再對於最先需要重視的要素加重行銷力量,就可使得企業充份達到策略行銷的目的。利用Kano 模式將有機專賣店顧客需求的品質要素加以分類,並採相對多數的方式將品質要素歸成五大類,包括:魅力要素、一維要素、當然要素、無差異要素、反轉要素
