黄河下游河道治理三维数值模拟研究
Research on the training of Lower Yellow River based on three dimensional numerical simulation
摘要
Abstract
This research aims to investigate the impacts of river training in the lower reach of the Yellow River through a three-dimensional model.Four design floods with different return periods were chosen from historical records as incoming hydrographs to simulate flood events in the region of Huayuankou to Aishan.Results under two training measures,i.e.,the measures without production levees and the new measure with two defence lines,were compared with each other.We analyzed the results with focus on the character of flood propagation,erosion and deposition,sediment transport,flood diversion and inundation on a typical floodplain.The results clearly revealed the training measure with two defence lines can not only protect the floodplains from being inundated,but also lead to sedimentation reduction in the whole reach compared with the measure without production levees.It indicates that the measure with two defence lines can benefit the prevention and reduction of flood disasters,and improve the sediment transport capacity.关键词
