摘要
黄河下游自孟津至高村属游荡性河段。自1958年以来,为了提供黄河下游河道治理的科学依据,曾经对游荡性河段的河床演变特征进行了系统的研究。本文主要介绍黄河下游游荡性河道的一些特点及河床演变的规律,并对造成游荡的原因作出初步分析。
The Lower Yellow River in Honan Province is characterized by a wide and shallow bed choked with sand bars.The stream is deflected in all directions into such a spread-out and intricately subdivided cross-section that no meanders developed.The river flows in a number of branching and reuniting streamlets with one of them as the main channel.This main river course ever shifts its position at an average speed of 10-300 m./day during floods.A shifting of the river course with as much as several kilometers is often recorded after the passage of a large flood,and the channel can be completely reverted its position from one bank to the other.
