水库汛期控制运用水位动态管理方案英文回答:Water level dynamic management is a crucial aspect of flood control in reservoirs during the flood season. It involves continuously monitoring and adjusting the water levels to ensure the safety and efficient utilization of the reservoir. In this article, I will discuss a comprehensive approach to implementing a water level dynamic management plan for reservoirs during the flood season.Firstly, it is important to establish a reliable and accurate monitoring system to track the water levels inreal-time. This can be achieved through the installation of water level sensors and gauges at various locations within the reservoir. These sensors should be connected to a centralized control center, where the data can be collected and analyzed.Once the monitoring system is in place, the next stepis to develop a predictive model that can forecast thefuture water levels based on historical data and current conditions. This model should take into account factorssuch as rainfall, inflow, outflow, and the reservoir's storage capacity. By accurately predicting the water levels, reservoir operators can proactively make decisions to prevent potential flooding or water shortages.In addition to the predictive model, it is essential to establish a set of operating rules and guidelines for managing the water levels during the flood season. These rules should consider the safety of downstream communities, the needs of water users, and the ecological requirementsof the river system. For example, if the water level is predicted to rise above a certain threshold, the operators may decide to release water in advance to create storage capacity for incoming floodwaters.Furthermore, communication and coordination among relevant stakeholders are crucial for effective water level dynamic management. This includes regular meetings andconsultations with local authorities, water users, and environmental agencies. By involving all parties in the decision-making process, potential conflicts and challenges can be addressed, and mutually beneficial solutions can be reached.To illustrate the importance of water level dynamic management, let's consider a hypothetical scenario. Suppose a reservoir is experiencing heavy rainfall, and the water level is rising rapidly. Without a proper management planin place, the reservoir may overflow and cause severe flooding downstream. However, with a water level dynamic management plan, the operators can closely monitor the situation and take timely actions, such as releasing wateror adjusting the outflow, to prevent flooding and minimize the impact on the surrounding communities.中文回答:水位动态管理是水库在汛期进行洪水控制的关键环节。
水库汛期控制运用水位动态管理方案英文回答:During the flood season, it is crucial to implement a water level dynamic management plan for reservoirs to effectively control water levels and prevent potential disasters. This plan involves monitoring and adjusting water levels in real-time to respond to changing weather conditions and water inflow rates.One of the key strategies in this plan is to use predictive modeling and historical data to forecast water levels and anticipate potential risks. By analyzing trends and patterns, we can make informed decisions on when to release or store water to maintain optimal levels in the reservoir. For example, if heavy rainfall is expected, we can proactively lower water levels to create more storage capacity and reduce the risk of overflow.Another important aspect of water level management iscommunication and coordination with local authorities and communities. It is essential to keep stakeholders informed about the current water situation and any planned actions to mitigate risks. By fostering open dialogue and transparency, we can build trust and cooperation among all parties involved in managing the reservoir.Furthermore, it is necessary to have contingency plans in place for emergency situations such as sudden increases in water inflow or unexpected equipment failures. By having protocols in place for rapid response and decision-making, we can minimize the impact of unforeseen events and ensure the safety of the surrounding areas.In conclusion, a water level dynamic management plan is essential for effective reservoir control during the flood season. By utilizing predictive modeling, communication, and contingency planning, we can proactively manage water levels and reduce the risk of disasters.中文回答:在汛期,实施水库水位动态管理方案对于有效控制水位、防止潜在灾害至关重要。
探讨水库汛期汛限水位的动态控制江口水力发电厂水库位于渠江流域州河的中上游河段,是一座以发电为主,兼防洪、灌溉的大型水利枢纽工程,总装机容量5.1万kW,额定水头26m,设计最大水头32.5m,水库总库容2.77亿m³,死库容0.73亿m³,兴利库容1.48亿m³,调洪库容1.02亿m³。
1 如何有效地调度水库洪水每年的5~10月之间,江口电站都要面临长时间的汛期,在该电站最初的设计方案中,汛期水位达到325m或其余月份水位达到330m时,就会采取开闸泄洪的手段。
有时洪峰入库流量较小,水库的泄洪能力绰绰有余,此时的洪峰能够全部泻出。
有时洪峰入库流量较大,已经超过水库的泄洪能力,就应当将大坝的泄洪口全部开启,避免水库内的水位继续上涨。
2 汛期调度运行方式现状江口电站水库分为主汛期和次汛期,两个时间段有着不同的泄洪手段。
在主汛期期间,整个水库的最高运行水位被严格制定在327m,当水库水位尚未到327m时,水库不采取任何泄洪操作。
当水位持续上升甚至超过了最高运行水位之后,就要根据实际情况来采取一定的泄洪手段,避免水库水位过高。
次汛期9~10月,在次汛期最高运行水位按328m控制。
3 汛期限制水位动态控制的必要性和可行性3.1 汛期汛限水位动态控制的必要性(1)根据四川省水利水电勘测设计院编制并报省水利厅审查批准的川水发[1993]基205号文批复中:在今后水库的运行管理中积累资料,总结经验,以使在适当时候对现行方案作进一步优化;(2)渠江流域具有在汛期前后易发春旱、夏旱、秋旱的特点,受汛限水位的限制,江口水库的发电效益受很大影响。
根据多年发电量分析,平均发电量不足设计发电量的80%;(3)水库汛期实行汛限水位动态控制可以减少弃水,增加汛期蓄水量,增发电量,使洪水资源得到优化利用,解决一场洪水5~6天后都没有水发电的现状。
3.2 汛期汛限水位动态控制的可行性(1)作为一个大型发电站,水库的水文环境检测手段十分丰富,不仅能够实时监测水、雨情的发展状况,还有一套完善的洪水预报系统,在洪峰来临之前就能制定好有针对性的应对措施。
