摘要: 
水田集水區與一般集在逕流表現上最大的不同,乃是水田田區周圍所
造成的窪蓄量,使其具有調蓄洪水功能,減低下游排水設施的負擔。 國
內研究田區降雨-逕流關係,多以低平地區為主本文為了探討稍具坡度的田
區流域之出流特性,以數值地形資料(GIS),利用地理資訊系統Arcview來分
析台中農田水利會所屬灌區之地文資料,選擇瓦嗂子溪排水幹線及十三寮
排水幹線作為研究流域。 本研究利用HEC-1模式之Snyder單位歷線法
及運動坡模式,以降雨頻率分析及設計雨型作為降雨輸入資料,並配合研究
流域之實際地文資料,進行田區流域逕流歷線模擬,進而分析田區之出流特
性及探討兩種模式之差異。 結果發現田區流域內水田所佔面積比例越
大,其削減洪峰流量及延緩洪峰到達時間的效 果越好。兩種模式特性方
面,出流時間Snyder單位歷線法較運動波模式來的快。另外,洪峰流量方
面,在降雨強度較小時,以Snyder單位歷線法所推估出來的值較運動波模式
所推估出的值來的高。

The characteristics of runoff in paddy field are different
form general basinbetween plots of farm land , its capacity of
storing storm. This research use the GIS ArcView software are
employed to analyzing main drainage channel in Tai-Chung
Gropland-Water conservancy. We choice Woa-Yau-Tzzydrainage
system and Shyr-Shan-Liai drainage system as experiment
catchment. We simulated the flood action by Kinematic model and
HEC-1 model. The design storm parrern of frequency-based
rainfall and geographic conditions are used as input date for
numerical simulations to investigate the characteristics of
runoff in two models. The result is that the larger the
proportions of paddy filed area are, the effects of the peak
flow rate reduced and of the peak time delayed are. On theaspect
of characteristic of two models, the runoff time in Snyder model
is less than Kinematic model, and the peak time in Kinematic
model is less than in Snyder model. Specially,on the smaller
rainfall intensity, the value declined by Snyder model is
larger that by Kinematic model.
