The impact of sedimentation on the long-term operational efficiency of reservoirs and regulatory measures
泥沙淤积对水库长期运行效能的影响及调控措施

摘要

泥沙淤积是影响水库长期运行效能的关键因素之一。随着水库使用年限的增加，泥沙淤积导致水库库容逐渐减少，水流动力学变化，影响水库的调节能力及水资源的有效利用。淤积不仅减少了水库的蓄水能力，还可能影响其防洪、供水和发电等多重功能。为了保障水库的正常运行，必须采取有效的调控措施，如定期清淤、优化蓄水调度和改善上游水土保持等手段。本文将探讨泥沙淤积对水库的长期影响，分析现有调控措施的效果，并提出更加有效的治理方案。

Abstract

Sedimentation is one of the key factors affecting the long-term operational efficiency of reservoirs. With the increase in the service life of reservoirs, sedimentation leads to a gradual reduction in the reservoir capacity, changes in hydrodynamics, and affects the regulation ability of the reservoir as well as the effective utilization of water resources. Sedimentation not only reduces the water storage capacity of the reservoir but may also affect multiple functions such as flood control, water supply, and power generation. In order to ensure the normal operation of the reservoir, it is necessary to adopt effective regulatory measures, such as regular dredging, optimizing water storage scheduling, and improving soil and water conservation in the upper reaches. This paper will discuss the long-term impact of sedimentation on reservoirs, analyze the effectiveness of existing regulatory measures, and propose more effective management solutions.
