Priliminary Studies On The Operation Regulation Of The Sustainable Use

The use of the sustainability of the reservoir determines the reservoir function and the benefit of the effect. Sediment deposition will lead to significant loss of storage capacity, particularly in sandy river reservoirs, which often affect the life of a reservoir level of the length of the main factors. Therefore, how to keep the reservoir by reducing the siltation of sustainable development is the need for adequate attention. Practice has proved that the use of a reasonable reservoir operation is an effective means to resolve this issue. Based on the analysis theory of sediment deposition and sediment the use of mathematical models for the sustainable operation mode Xiluodu reservoir study,major achievements include:(1) By analyzing the typical muddy reservoirs storing clear manner of the deposition characteristics of river-type reservoir sedimentation processes come to the general law of development and its influencing factors. The results show that the reservoir operation regulation and sedimentation patterns of development and degree of close relationship: The lower limit water level, sedimentation reach an initial equilibrium time shorter, post-deposition volume of the smaller reservoir is the key to sustainability factors ; Storage time of the later, more slowly increased sedimentation, siltation into the initial balance of a longer time, less the amount of siltation。(2) To Xiluodu Reservoir, the use of sediment mathematical model analysis of the reservoir in the original design of the development of the program is running under the deposition characteristics.(3) Xiluodu of proposed reservoir on the different operation regulation, to study the comparative their deposition conditions and benefit and the effect ,explore the sustainable reservoir operation regulation.The results showed that the basic framework for storing the clear and releasing the muddy,double flood control level scheme operation regulation by adjusting the distribution of sediment along the way to achieve sedimentation reduction compatibilizer, to increase the reservoir is more prominent role in the long run the benefits.(4) Xiluodu reservoir operation regulation for further analysis of sustainability, result shows that the reservoir in that mode, both the benefit and the effect and sustainable use of the reservoir improved a lot.
