Description
Summary:碩士 === 國立成功大學 === 水利及海洋工程學系 === 84 === A flooding-drainage model which combinates flooding model and drainage network model by means of weir flow theory is developed to simulate the interaction between the rainfall- runoff in the flood-plain and the flow in the drainage network system. The inundated process due to over-design flood and the function of drainage network system can be understood with the help of this present model. The drainage network system model is developed using the linar-fully-implicit scheme wirh matrix- double-sweep method based on de-Saint Venent equations. A quasi- two-dimension flooding model is developed to simulate the inundated process of highly designed flood-plain which including roads and ridges.With the use of hypothetical design case, the conservation of discharge and the transfer of water between flood-plain cells and drainage network system are discussed. The reasonable results show that the capability of the combinated model has been verified.The inundated process due to heavy rainfall in the South-plain of Pa-chung River is simulated to examine the applicability of this combinated model. The findings indicate that this model is capable of simulating the interaction between the flood-plain and drainage network system. However, more filed data are necessary to calibrate the hydraulic parameters.
