摘要: 
基於保護整體生態,排水設施應減少使用混凝土的比例,非主要排水設施更可以草溝取代,進而降低整體排水系統混凝土的使用量。為尋求合適之草溝鋪設排水設計,本研究以三種草種及二種土壤進行渠槽實驗,擬針對草溝之水理設計進行分析、探討。
結果發現不論土壤底床為黃壤或紅壤,草層為何種植生,現在常用於估算流速之曼寧公式所求得之流速皆偏大,屬於高估的情況,其中假儉草高估之倍數約1.2至3倍,而百慕達草及類地毯草高估之倍數約1.2至4倍。
於應用例之結果中,發現以曼寧公式估算流量所得結果之高估幅度相當大,最大可達44%,顯示其應用於斷面設計上容易與真實情況產生很大差異。

In order to protect the ecological system, the proportion of using concrete to construct drainage facilities should be reduced, and some non-major drainage facilities could be replaced with grassed channels for reducing the use of concrete. This experiment was executed with three kinds of grass and two kinds of soil to analyze the grassed channel design and to seek the best one.
The result shows that the velocity estimated by Manning's formula is always over-evaluated and larger than the measure one whatever the channel bottom and the vegetation are. The over-evaluated degree of Centipede grass (Eremochloa ophiuroides) is about 1.2 to 3 times, and the other ones of Bermuda grass (Cynodon dactylon) and Carpet grass (Axonopus affinis) are about 1.2 to 4 times.
In the application, the estimated discharge by Manning's formula is over-evaluated to a large degree, and the most one can be up to 44%. It shows that this method applied to drainage facilities design is often different from the fact easily.
