汉江丹江口水利枢纽建成后,其下游河道来水来沙条件发生重大变化,河道长距离冲刷,河势相应有不同程度的调整。目前河床冲刷已基本达到相对平衡,加上30a来的治理,汉江中下游总体河势已基本稳定,但局部河势仍在调整,有的河段河势变化还比较剧烈。建议尽快制订汉江中下游河势控制近期规划,尽早全面实施。
After the completion of Hanjiang Danjiangkou Water Conservancy Project, significant changes have taken place in the conditions of incoming and outgoing water and sediment in the downstream reaches of the Hanjiang River, resulting in long-distance erosion of the rivers and corresponding adjustments of the river potential in varying degrees. At present, the riverbed erosion has basically reached a relative balance. Together with the 30-year treatment, the overall river regime in the middle and lower reaches of the Han River has basically stabilized. However, some river regimes are still being adjusted, and some river regime changes are still relatively severe. It is suggested that a plan for river control of the middle and lower reaches of the Han River be formulated as soon as possible so that it can be implemented as soon as possible.
