Flood Routing in River-Reservoir System:Research Advances and Existing Problems
摘要
Abstract
In the scheduling of river-type reservoir, the impact of inflow flood, artificial regulation, and river basin topography on the flood routing process should be considered. By summarizing the research findings of flood wave features and dynamic reservoir capacity, we made it clear that the scheduling of river-type reservoir should be ac-complished by coupling hydrologic and hydrodynamic models, and meanwhile that attention should be paid to the disturbance of artificial scheduling on the stage-discharge relation at dam site. We summarized that the effect of wa-ter flow structure on riverbed roughness should be taken into consideration in the calculation of reservoir flood rou-ting. Furthermore, we reviewed the research achievements up to now of the flow characteristics near dam and point-ed out that the three-dimensional flow characteristics near dam are remarkable. Taking the cross-section near dam as the boundary condition may cause systematic errors in calculation. In order to improve the accuracy of flood rou-ting model, in future we should conduct in-depth research on the influence of manual regulation on the conveyance capacity of the cross-section near dam and roughness calibration.关键词
