摘要: 
本研究是以直列二段式水筒模式作為基礎,在不易排水的地方增設一個遲滯水池來模擬在經過一場暴雨之後其淹水的情形。在未設置遲滯水池之前,降雨情況不是很大的情形下,使用複合水筒模式來模擬水稻田區逕流之情形,就已經模擬的相當不錯。
在本文中,模擬的試驗田區是位於台南-南安溪寮之水稻田區。本文模擬的降雨資料共有六場,時間從2-3天至1個多月不等。降雨強度六場降雨均不一樣,分別探討模式對於短時程和長時程以及暴雨和非暴雨時模式的適用性和模擬的效果。
由模擬結果可知,由觀測資料所率定出來的水筒參數,可以代表此地區之水田水筒之參數。另外,在降下暴雨的時候遲滯水池均能發揮其功用,降低洪峰出流量,達到遲滯洪水的目的。在低水位時,水稻田區的出流量不受到遲滯水池的影響,正常的出流。
因此,本研究在不同的降雨歷程當中皆有不錯的模擬效果。

In this study, under the retarding basin construction, the complex tank model was used to simulate the state of inundation after storm at difficult drainage area. It was proved that the complex tank model can be used to simulate the runoff of paddy field and gets a good result under moderate rainfall and disuse of the retarding basin.
The paddy field of this study was located in Tainan. Six rainfall data with the duration of two days to one month and different rainfall intensities were adopted. The simulation effects were discussed for the short/long duration and storm/nonstorm.
By the results of simulation, it is proved that the observational rating values can be used to represent the real tank parameters. On the other hand, the retarding basin can reduce peak flow in storm, and retain steady flow in low water level. In conclusion, the good simulation effects are proved by different rainfall hyetographs.
