"Real-Time Monitoring and Assessment of Water Quality in Dams in Yunnan Province using Online Sensor Network"
Abstract:
With the rapid development of hydropower construction in China, the management and protection of dams have become increasingly important. One of the key aspects is ensuring the safety and reliability of the reservoir system, which largely depends on the health of the water in the lake. Therefore, it is essential to implement efficient and reliable monitoring methods for water quality. In this context, we propose a real-time monitoring and assessment system for water quality in dams based on an online sensor network.
The system employs advanced sensors that can measure various parameters related to water quality, such as pH value, dissolved oxygen, temperature, and total suspended solids. Data from these sensors is transmitted through wireless communication channels to a data logger and a central server. The server collects, processes, and stores the data in a database, which can be accessed remotely for real-time monitoring and analysis.
We have deployed this system at several major dams in Yunnan Province, China, and the results show that the system is highly effective in detecting potential water quality issues before they escalate into major problems. For example, we detected a significant drop in pH value and dissolved oxygen levels at one of the dams, indicating that the water was becoming more acidic and less oxygenated. This information was used to take corrective measures, such as releasing some of the water from the lake to maintain a stable ecosystem.
In addition, the system has helped us to track changes in water quality over time, identify patterns and trends, and develop strategies for improving water quality. For instance, we found that the levels of Total Nitrogen and Phosphorus increased significantly during peak tourist season, which suggested that these nutrients were being released by the activities of visitors. Based on this observation, we proposed measures to reduce the nutrient load on the lake, such as promoting eco-tourism and implementing strict regulations on waste disposal.
Overall, our real-time monitoring and assessment system for water quality in dams provides valuable insights into the health of reservoir systems and enables timely actions to protect aquatic ecosystems and ensure public safety. We hope that our work can inspire further research and development in this field and contribute to the sustainable management of hydropower resources.
