第六章 結論與建議
6.2 建議
1. 現階段國內外對於一維與二維水理輸砂河道模式之發展已相當成 熟，且朝向三維動床模式發展。然而，相關水理與輸砂之複雜交 互機制、輔助關係式、物理機制之定量方法等，實為影響模式合 理性與適用性之關鍵因素。對於河道變遷行為之新興議題，如軟 岩沖刷等，在相關物理機制與沖刷行為尚未完全掌握前，應根據 探討課題尺度，採用發展較成熟之水理輸砂模式循序漸進探討。
2. 本研究之軟岩河床沖刷模式對於水工構造物如橋墩、攔河堰、丁 壩壩頭與固床工交界處等局部流場與沖刷問題並不適用，雖相關 構造物可藉由格網產生進行幾何與高程之設定，但其局部區域之 流場與沖刷受到水深方向流場與局部紊流影響，屬三維水理現 象，使用水平二維模式有其先天上之限制，後續建議可根據本研 究模式基礎，持續探討軟岩河床之三維水理與沖淤行為。
3. 現場案例之模擬中，部分深槽最低點、多槽水流與左右邊界位置 之模擬誤差，係與邊界格網密度、人為擾動、航照圖轉地形資料 忽略高灘地地表植生等因素相關，此可為後續研究改善之項目。
4. 現場河川大多缺乏水流沖洗載與懸浮載之粒徑級配資料，而沖洗 載所占比例與洪水大小之動態過程關係，其對軟岩河床沖淤影響 程度等，為後續研究值得探討之課題。
5. 根據相關文獻，遷急點變化過程與水流強度、河床材料及地形相 關，因此未來除了現有之臨界坡度判斷機制外，應可再考慮如剪
力、流功等關係，或結合明渠水力學相關概念，使現有沖蝕率模 式更具力學機制，此為後續值得探討之課題。
6. 後續建議再藉由其他河川之現地調查資料進行分析，持續驗證本 研究開發之軟岩沖刷模式，使本模式更具一般化之實用價值。
