在系统分析实测资料和洪水期间航片资料的基础上,概化了黄河下游不同时期漫滩洪水演进模式,初步揭示了中常洪水演进特点及发生机理,指出滩区行洪及滞洪条件的改变是“96·8”洪水传播时间增长、洪峰沿程变形剧烈的主要原因,洪峰变形及传播时间增长主要发生在具有广阔滩地的夹河滩至艾山河段。
Based on the systematic analysis of measured data and aerial photos during the flood period, the evolution pattern of floodplain flood at different periods in the lower Yellow River is generalized, and the evolution characteristics and mechanism of the flood in the midsummer are preliminarily revealed. It is pointed out that the change of flood discharge and detention conditions in the floodplain is “96.8 ” flood propagation time, the main reason for the severe deformation along the flood peak, flood peak deformation and propagation time growth occurs mainly in the broad beach of the folder River to Iksan section.
