| 摘 要： | 根据1997年实施的黄河下游窄河段挖河固堤启动工程的观测资料,分析了挖河对河道冲淤变化及水面线调整的影响。研究表明,在一定的时段和一定河段内,挖河对于减少河道淤积及降低洪水位都有较好效果。对挖沙减淤效果的基本概念也作了讨论。

| Abstract: | According to the observed data of starting works dredging river and strengthening dike in narrow reach of the lower Yellow River in 1997, the effect of dredging river on erosion-deposition variation in the channel and regulation of water surface profile is analyzed.The results show that the dredging river has a good effect on reducing channel's deposition and lowering flood stage in a certain period and a certain reach.The basic concept of effect on dredging sediment for deposition reduction is discussed also. |
