1. 雖然本模式已能模擬設置潛板之功能，但尚在定床的階段，日後 繼續擴充至動床，則能瞭解潛板對實際河川彎道之影響，不僅是 流速的改變，也能對底床的變化加以探討。

2. 本模式已有模擬主支流交匯之功能，河流流經交匯處會產生局部 的沖刷或淤積，因此可以藉由潛板的設置改變該處的泥沙運移行 為，以改善交匯處之沖刷或淤積情形，此一現象為日後可研究之 課題。

3. 當河川有局部突擴或收縮之河段，會在岸邊產生渦流導致底床淘 刷，因可加以探討突擴或收縮之河段佈設潛板後之泥沙沖淤情 形。

4. 本文之潛板理論對潛板之幾何形狀僅探討其長度與寬度，並未考 慮潛板的厚度，但實際上潛板的厚度會影響拖曳力的大小，進而 改變二次流流速，日後若有對潛板厚度影響提出新的論點，可將 潛板厚度因子納入數模中。
