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.
