摘要: 河流的演变主要决定于流域来水来沙条件及河道边界条件。在多沙河流的治理上,不应仅仅局限于改变河流的边界条件(如加高加固堤防,固定中水河槽等),而应发挥人的主观能动性,同时考虑如何利用上游的水库(或其他工程,如放淤工程),合理调节水沙过程,使下游河道朝有利的方向发展。

Abstract: For the sake of flood and sedimentation control down-stream of the reservoirs, a study has been carried out on the ways of operation of several reservoirs in the Lower Yellow River. A program on the regulation of flow and sediment is suggested with the following purposes: (1) To reduce the rate of aggradation of the river channel by raising its sedi-ment transport capacity; (2) To guide the sediment to be deposited in the desired position; and(3) To use the sediment impounding storage of the reservoir to its full capacity so that loads in the lower reach can be lessened to a certain extent.
