| Abstract: |
The surface inundation under influences of pumping-station and flood-gate operations has been simulated. The pumping-station and flood-gate systems affect water flow discharge between the river and drainage basin. A numerical model, consisting of a one-dimensional dynamic-flood routing for a river and a two-dimensional zero-inertial overland flow model for a drainage basin, is developed to simulate river flow and basin inundation during flood. The study area, located in the western part of Metropolitan Taipei city is selected for simulation. The rainfall data, geographic features, capacity of pumping-station and flood-gate operations are input for numerical simulations. The field recorded data of Typhoon Herb event in 1996 is used for the calibration of the numerical model. The model is also applied to simulate the inundation in the study area under the full operation of pumping-station and the exact closure if flood-gate. |
