泥沙淤积是多沙河流中小型水库运用管理中的突出问题。如何运用管理好水库,实际上是如何减少泥沙淤积,确保水库的长期运用。在防治水库淤积中,以往把“加大死库容”,“修拦泥库”,“加高坝体”等,认为是防治多沙河流上水库泥沙淤积的主要措施。实践证明,有限的库容根本无法拦截无限的泥沙,在水土流失严重地区,往往坝体的加高,赶不上水库淤积的速度。这些消极的防御办法,不能从根本上摆脱泥沙的威胁。在与泥沙作斗争的
Sedimentation is a prominent issue in the management of small and medium-sized reservoirs in the Dousha River. How to use reservoir management is actually how to reduce sediment deposition to ensure the long-term use of reservoirs. In the prevention and control of siltation in reservoirs, “increasing dead storage capacity”, “repairing mud silos” and “raising dam” have been regarded as the main measures to prevent sedimentation in reservoirs on the mainstream of the Dousha River. Practice has proved that limited storage capacity simply can not intercept unlimited sediment, in areas where water and soil erosion are serious, often the height of the dam body can not keep up with the rate of reservoir siltation. These negative defensive measures can not fundamentally get rid of the threat of sediment. In the fight against sediment
