| dc.description.abstract | A distributed watershed run-off model is developed to simulate the surface
water distributions on the typhoon events. The factors of hydrology are
considered in the model, such as rainfall, interception, infiltration, overland flow,
and channel flow. To evaluate this mode, we simulate the surface water
distributions of Shihmen watershed on the events of typhoon Herb, Zeb, and
Nari.With this simulation, we analyze the changes of surface water distributions
in time and space.
We also validate the effects of computation time, space resolution,
infiltration factor, interception factor, and the calculating method of rainfall
distribution on this model.The watershed run-off model can be used to simulate
the hydrology circulations in the watersheds, and calculate flood peak discharge
as well as duration effectively. Since the hydrologic cycle is simplified in the
model, there are some biases in the simulation results. Further studies of the
biases can be performed. | en_US |
