摘要
根据实测资料分析了1999年10月～2007年10月黄河下游高村-艾山河段来水来沙及冲淤变化情况，结果表明：高村-艾山河段冲刷1．15亿m^3，占全下游冲刷量的10．5％，同流量水位下降0．88～1．47m；下游各河段河道断面得到相应调整，冲刷强度沿程逐渐减弱，高村以上河段的断面形态调整展宽和下切同时进行，高村以下河段以下切为主；河床明显粗化，主槽过流能力明显增强。
The paper analyzes the variations of coming water and sediment,scour and fill of Gaocun-Aishan section in the period from October 1999 to October 2007 based on the observed data.The outcomes show that the scour volume of Gaocun-Aishan section is 115 million m3,making up 10.5% of the total of the lower reaches and the decrease of water level in the same discharge is 0.88-1.47 m;after appropriate regulation of each section on the downstream,the scour intensity along the river reduces regularly,the cross-section morphology above Gaocun is widened and undercut simultaneously and the section below Gaocun mainly undercut and;the river bed obviously becomes rough and flowing capacity of the main channel is increased remarkably.
