What is water‑logging point monitoring? Let’s take a look.

　　With the development of China’s economy, across the country… Waterlogging Point Monitoring Infrastructure is also being gradually improved, and certain technological advances have been made. However, many flood‑prone areas lack stringent requirements for the monitoring capabilities of instrumentation, and the equipment itself remains inadequate, with significant shortcomings and limitations. In some cases, traditional methods are still employed for monitoring, resulting in suboptimal analytical performance and other substantive issues.

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

　　“The Internet” represents a further practical application of internet‑based thinking, providing a broad digital platform for the reform and innovative development of socio‑economic entities. In response to the shortcomings of traditional water‑level monitoring at flood‑storage and detention sites, this paper proposes a solution for urban flood‑storage and detention site water‑level monitoring under an “Internet”‑based framework.

　　Urban flood‑prone site monitoring based on Internet technologies refers to the activities undertaken by hydrological monitoring networks to observe, analyze, and compute factors such as water volume, water level, and temporal patterns at specific flood‑affected 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.

　　Urban flood‑prone site monitoring based on Internet technologies provides accurate analytical data and planning outcomes for rainfall forecasting, urban planning, environmental protection, and other areas. It has also amassed a relatively comprehensive set of hydrological monitoring records from flood‑affected locations, yielding significant environmental and social benefits.

　　The flood‑depth curve at the flood‑monitoring station shows a trend that overlaps with the cumulative rainfall curve, indicating a strong correlation between the two. Since both cumulative flood depth and cumulative rainfall are cumulative measures, they exhibit a high degree of correlation and are readily comparable. The cumulative flood duration lags behind the onset of cumulative rainfall. By leveraging this time lag, we can use the cumulative rainfall data recorded at the inundation‑monitoring site to forecast the evolving flood situation, enabling proactive measures to mitigate and manage potential flooding.

　　When the rainfall intensity curve rises sharply, the flood depth curve begins to increase after a certain time. As rainfall intensity decreases, the inundation depth curve shows no significant increase or decrease. Combined with… Waterlogging Point Monitoring With the inundation time established, we have projected the future water‑level trends in the flooded area. Once the data are complete, by integrating regional topography and urban drainage network information, it is possible to forecast drainage times and to develop scientifically sound, effective solutions for upgrading drainage infrastructure in the affected zones.
