| Summary: | 碩士 === 國立中興大學 === 土木工程學系所 === 105 === To observe the rainfall-runoff condition and reckon the water storage capacity of sustainable communities, this study adopted the flexible adjusted complex tank model and Multi-start Powell method as parameter index. The complex tank model is adjustable to meet the field requirement, and to reflex the actual water-runoff condition. The study is tested at Huafan University with simplified multi-segment tank model to simulate local rainfall-runoff condition, and the model is tested in three parts as flat rooftop, tilted rooftop and ground surface.
This study simulated rainfall-runoff in two rainfall incidents, and assumed four different models to adjust parameters. The simulation result showed that Model 1 is relatively matched to the actual condition than the other models. Its average GM error, 0.514, is more reasonable in the rooftop and ground surface parameters.
