As an important part of the water system, the hydrological status of small and medium-sized rivers is directly related to the local water resources utilization, flood prevention and mitigation, and ecological environmental protection. Therefore, it is of great significance to build an efficient and accurate hydrological monitoring system for small and medium-sized rivers to improve the level of water resources management and ensure water security. In this paper, the construction and application of hydrological monitoring systems for small and medium-sized rivers will be detailed, in order to provide useful references for related work.
The construction of the hydrological monitoring system of small and medium-sized rivers is proposed based on the many challenges faced by the current water resources management. On the one hand, with the intensification of climate change and human activities, the hydrological conditions of small and medium-sized rivers are becoming more and more complex, which puts forward higher requirements for monitoring methods and technologies. On the other hand, the traditional hydrological monitoring methods have problems such as low accuracy and low efficiency, which are difficult to meet the needs of modern water resources management. Therefore, the construction of a new hydrological monitoring system for small and medium-sized rivers has become an urgent need for water resources management.
The following principles should be followed in the construction of the hydrological monitoring system of small and medium-sized rivers:
Scientific principle: The system construction should be based on scientific hydrological theory and technical methods to ensure the accuracy and reliability of monitoring data.

Advanced principle: The system should adopt advanced technology and equipment to improve the accuracy and efficiency of monitoring and reduce operation and maintenance costs.
Scalability principle: The system should be well scalable and able to adapt to changes and upgrades in future monitoring needs.
The construction of hydrological monitoring system for small and medium-sized rivers mainly includes the following aspects:
Layout of monitoring stations: According to the hydrological characteristics and monitoring needs of small and medium-sized rivers, the monitoring stations should be reasonably arranged to ensure the comprehensiveness and representativeness of the monitoring data.
Selection of monitoring equipment: According to the actual situation and monitoring needs of the monitoring site, select appropriate monitoring equipment, including water level meter, flow meter, water quality analyzer, etc.
Data transmission and storage: Establish a stable data transmission network, transmit monitoring data to the data center in real time, and effectively store and manage it.
Data processing and analysis: Using data processing and analysis technology, the monitoring data is deeply mined and analyzed, valuable information is extracted, and decision-making support is provided for water resources management.
The application practice of hydrological monitoring system for small and medium-sized rivers is mainly reflected in the following aspects:
Water resources management and scheduling: Through real-time monitoring of hydrological parameters such as water level and flow of small and medium-sized rivers, it provides a scientific basis for water resources management and dispatch, and realizes the optimal allocation and efficient utilization of water resources.
Flood prevention and disaster reduction: The system can monitor the water level changes of rivers in real time, warn flood disasters in time, and provide strong support for flood prevention and disaster reduction.
Ecological environmental protection: By monitoring the water quality of small and medium-sized rivers, water pollution problems can be detected in time and data support can be provided for ecological and environmental protection.
Scientific research: The long-term and continuous monitoring data provided by the system provide valuable information for hydrological scientific research and help promote the development of hydrological science.
With the continuous progress of science and technology and the deepening of application, the development prospect of hydrological monitoring system for small and medium-sized rivers is very broad. In the future, the system will be further intelligentized, automated and integrated to improve the accuracy and efficiency of monitoring. At the same time, with the application of big data, cloud computing and other technologies, the system will conduct more in-depth analysis and mining of monitoring data to provide more comprehensive and accurate services for water resource management.
The construction and application of hydrological monitoring system for small and medium-sized rivers is an important measure to improve the level of water resources management and ensure water security. Through the scientific construction of the system, the rational layout of monitoring stations, the selection of appropriate monitoring equipment and the effective use of monitoring data, we can achieve real-time monitoring and accurate management of the hydrological status of small and medium-sized rivers, and provide strong support for water resources management. In the future, with the continuous progress of technology and the continuous expansion of application scenarios, the hydrological monitoring system of small and medium-sized rivers will play a more important role in water resources management.
In summary, the construction and application of hydrological monitoring system for small and medium-sized rivers is of great significance. We should continue to strengthen system construction and technological innovation, continuously improve the performance and function of the system, and contribute more to the cause of water resources management. At the same time, we should also strengthen cooperation and exchanges with other fields to jointly promote the progress and development of water resources management.
