摘要
游荡型河道河势演变不仅包含渐变过程,也包含突变过程。河势突变是指游荡型河道局部或整体河势在短时间内发生大幅度的调整。河势突变给河流防洪、供水安全及河流治理带来了重大挑战。如果在某些情况下对河势突变适当加以利用,可有效提高河道整治工程的控导能力,增强河势稳定性。从游荡型河道河势突变调整的现实意义、内涵和研究方法等方面评述其研究进展,指出现有研究存在的不足,并提出未来开展河势突变研究需要重点关注的问题,为下一步深入系统开展游荡型河道河势突变研究指明方向。
The river regimechange of wandering channel may contain not only gradual process, but also abrupt process. Abrupt change of river regime means a massive change of part or whole of a channel in a short time. The abrupt change of river regime brings great challenges to the safety of flood control, water supply and river harnessing. In some cases, if the abrupt change can be used effectively, the control ability of river training project may be improved. In this paper, definition, connotation, research progress and research method on abrupt change of river regime had been introduced and reviewed respectively. And then, the shortcomings of the research had been pointed out and some points about abrupt change of river regime which needed to be paid attention to in the future had been put forward, pointing out the direction for the further study on abrupt change of river regime.
