Research on Monitoring Waterlogging Hotspots Based on Internet Technology

　　 Waterlogging Point Monitoring Data are of great significance for studying urban runoff and flow‑convergence patterns. By leveraging “Internet Plus” technologies to integrate hydrological monitoring systems with the internet, we can provide information services for monitoring waterlogging hotspots, achieve integrated data management, significantly shorten the lead time for hydrological monitoring and early warning, enable proactive development of urban flood‑control and drainage plans, reduce the workload of hydrological personnel, and embody a people‑centered approach.

　　1 Current Status of Hydrological Monitoring

　　With the development of China’s economy, hydrological monitoring infrastructure across the country has been steadily improved, and certain technological advances have been achieved. However, many hydrological monitoring stations lack stringent requirements for instrument performance, and their equipment remains inadequate, exhibiting significant shortcomings and limitations. Moreover, in many areas, traditional methods are still employed for monitoring water‑logging points, resulting in suboptimal analytical outcomes and other substantive issues.

　　Traditional monitoring of urban flood‑prone areas requires hydrologists to conduct manual water‑level measurements at detention basins, posing challenges in ensuring the accuracy and reliability of the data. With advances in science and technology, electronic measuring instruments have replaced manual methods, significantly reducing the labor involved in hydrological monitoring. Nevertheless, hydrological monitoring typically necessitates a comprehensive consideration of multiple factors, such as watershed runoff and flow dynamics, as well as long‑term rainfall‑runoff analyses. Simply upgrading monitoring technologies for a single point at a specific moment is insufficient.

　　“Internet Plus” represents a further practical application of internet‑centric thinking, providing an expansive digital platform for the reform and innovative development of socio‑economic entities. In response to the limitations of conventional flood‑prone site monitoring approaches, this paper proposes a solution for water‑level monitoring at urban flood‑storage and detention sites under the “Internet Plus” framework.

　　2 Data Analysis of Measurement Points

　　Internet‑based monitoring of urban waterlogging hotspots refers to the activities undertaken by hydrological station networks to observe, analyze, and compute factors such as water volume, water level, and temporal patterns at specific flood‑prone locations within a city. This approach facilitates the integration and optimization of hydrological monitoring, expands its infrastructural support, and enables real‑time control and refined management of urban flood‑storage and detention sites.

　　Based on “Internet Plus” technology Waterlogging Point Monitoring It has provided accurate analytical data and planning outcomes for urban rainfall forecasting, urban planning, environmental protection, and other areas; it has also compiled a relatively comprehensive set of hydrological monitoring records from urban flooding‑prone sites, yielding significant environmental and social benefits.
