The core foundation of water hazard detection solutions lies in high-performance sensing technology and a reliable data communication system. Currently, key monitoring components such as water level, rainfall, and flow velocity still have shortcomings in terms of accuracy, stability, and adaptability to extreme climates, with some high-end equipment relying on imports. With the continuous progress of domestically produced high-sensitivity sensors, low-power IoT chips, and edge intelligence modules, the upstream industry is accelerating its localization and independent innovation. In the next three to five years, intelligent sensing terminals with high precision, low cost, and easy scalability will become the core driving force for large-scale industry applications and the implementation of smart disaster prevention systems.

In the midstream segment, the industry is evolving from traditional "single-point monitoring" to "intelligent integrated prevention and control platforms." How to achieve real-time fusion and dynamic modeling of multi-dimensional data (meteorology, hydrology, geology, topography, etc.) has become a key direction for system optimization. The combination of artificial intelligence, cloud computing, and digital twin technology enables the system to have trend prediction, hierarchical early warning, and automatic scheduling capabilities. In the future, integrated monitoring platforms capable of autonomous learning, cross-regional linkage, and decision visualization will become the core competitive advantage in the field of water hazard prevention and control.

3. Key Drivers:

Climate change is making extreme weather events more frequent, and the global flood control situation is becoming increasingly severe.

Frequency of disasters such as heavy rainfall, flash floods, and urban flooding poses a continuous challenge to urban safety and watershed management. Data from the UN WMO shows that in the past two decades, economic losses from floods have accounted for about one-third of total natural disaster losses. Faced with increasing risks, countries are shifting from "post-disaster relief" to "pre-disaster prevention," actively building comprehensive monitoring and early warning systems. Water hazard detection solutions, with real-time perception, dynamic analysis, and rapid response as their core capabilities, have become an important supporting technology for addressing climate risks and strengthening flood control systems.

Policy investment in smart disaster prevention systems continues to provide a solid guarantee for industry development.

China, through its "Overall Plan for Smart Water Conservancy Construction" and "Action Plan for Improving Watershed Flood Control Capacity," has clearly proposed to achieve integrated hydrological monitoring, early warning scheduling, and emergency response. The United States, the European Union, and Japan are also promoting digital flood control systems and smart disaster prevention projects. The continuous investment in policies by various countries has not only improved the technological level of disaster prevention systems but also accelerated the industry's upgrade towards intelligence, networking, and platformization.

Waterway hazard detection systems are being deeply integrated with smart city and digital twin technologies to build a "digital hub" for comprehensive flood control.

By integrating meteorological, hydrological, topographical, and historical data, the system can dynamically calculate flood propagation paths and risk areas, enabling accurate forecasting and emergency command support. The widespread application of digital twin watersheds is enabling flood control management to move from static monitoring to intelligent analysis and automated decision-making, significantly improving urban drainage scheduling efficiency and disaster response capabilities.

Major Obstacles

Aging Infrastructure and Inadequate Data Acquisition

Many cities and river basins have long-established hydrological monitoring systems, but outdated equipment, sparse deployment, and insufficient sensor accuracy result in incomplete or delayed real-time monitoring data, hindering timely early warning and decision-making. Furthermore, inconsistent monitoring standards across different regions and high barriers to data sharing limit cross-regional collaborative monitoring and risk assessment, impacting the overall system's reliability and response efficiency.

High Difficulty in System Integration and Algorithm Model Application

Water hazard detection involves multi-source heterogeneous data from meteorology, hydrology, geology, and geographic information, leading to significant system integration complexity. The lack of unified standards across different sensing devices, communication protocols, and data formats increases the technical difficulty of data fusion and model training. Moreover, the adaptability of AI prediction algorithms and digital twin models to different water environments remains limited, requiring extensive calibration data and long-term validation for practical implementation.

High Construction and Maintenance Costs and Immature Business Models

Investment in high-precision sensing equipment, edge computing nodes, and cloud platforms is substantial, especially in complex environments such as mountainous areas and reservoirs, where installation and maintenance costs are even higher. In some regions, projects still rely heavily on government investment, with insufficient willingness from private capital. The lack of a mature revenue mechanism for data services and risk assessment has resulted in a singular profit model for the industry, hindering its continued expansion and technological advancements.

Industry Development Opportunities

The Integration of Smart Disaster Prevention and Digital Twin Technology Brings System Upgrade Opportunities

With the maturity of digital twin, IoT, and AI technologies, water hazard detection is transforming from "passive monitoring" to "proactive prediction and intelligent decision-making." By constructing digital twin watershed models, real-time simulation and risk prediction of dynamic elements such as rainfall, water level, and flow velocity can be achieved, improving the scientific nature of flood control scheduling and emergency response. In the future, AI-based intelligent hydrological models will drive the system's evolution from a monitoring platform to a comprehensive disaster prevention decision-making center.

Policy Support and Accelerated Investment in Smart Water Conservancy Construction

Global climate change and increasing urban flood control pressures have led governments worldwide to continuously increase investment in flood control informatization and water security governance. China's "Overall Plan for Smart Water Conservancy Construction," the EU's "Floods Directive," and the US FEMA disaster prevention program have all provided long-term financial support and standardized guidance for the industry. Driven by policy, the implementation of large-scale projects will drive comprehensive growth in upstream and downstream equipment manufacturing, software development, and system integration.

The demand for climate-resilient cities and infrastructure construction is rapidly increasing.

Accelerated urbanization and frequent extreme rainfall have made urban flood control and watershed flood prevention key areas of infrastructure development. Water hazard detection systems, as a core component of climate-resilient cities, will be widely used in urban drainage networks, reservoir scheduling, river management, and emergency command centers. In the future, with the deepening integration of smart city and sustainable development concepts, this field is expected to become a new growth point for the integration of disaster prevention and technology.

4: Downstream Industry Analysis

The focus is on three core application areas: watershed flood control and reservoir group scheduling, urban smart flood control system construction, and ecological river and lake and infrastructure safety supervision.

I. Watershed Flood Control and Reservoir Group Scheduling Management

The coordinated scheduling of watersheds and reservoir groups is one of the most widely applied and technically demanding areas for water hazard detection solutions. Faced with challenges such as uneven spatial and temporal distribution of rainfall, increased suddenness of flood peaks, and aging reservoir facilities, countries are actively promoting the construction of watershed-level intelligent flood control systems. According to data from the United Nations Water Resources Assessment Agency, approximately 70% of major watersheds globally face varying degrees of flood risk. China's "Smart Watershed Flood Control Project" and the "National Water Network Construction Plan" explicitly require the realization of multi-reservoir joint scheduling, full-process flood monitoring, and intelligent decision-making. The system, through the deployment of multi-dimensional sensing devices such as rain gauges, water level gauges, flow meters, and seepage pressure sensors, combined with AI prediction models and a digital twin watershed platform, can dynamically simulate the flood evolution process and optimize scheduling plans. In the future, integrated monitoring systems combining satellite remote sensing, cloud computing, and intelligent algorithms will become a key support for the management of large river basins and reservoir groups, realizing a modern flood control system integrating "prevention, control, regulation, and early warning."

II. Construction of Smart Urban Flood Control Systems

With the increasing frequency of extreme rainfall events and the rising proportion of impervious surfaces in cities, urban flood control and drainage scheduling have become significant growth areas for detecting potential water hazards. The system collects real-time data on the operational status of urban drainage systems by deploying surface water level sensors, rainfall monitoring stations, pipeline flow meters, and video monitoring nodes. Combined with AI algorithms and a GIS visualization platform, it can achieve early warning of waterlogging points, automatic start/stop of pumping stations, and intelligent control of gates. According to joint research data from the Ministry of Housing and Urban-Rural Development of China and the World Bank, the input-output ratio of smart flood control systems is as high as 1:6, effectively reducing losses from sudden flooding by more than 70%. Cities such as Shanghai, Shenzhen, and Guangzhou have fully embedded water hazard monitoring modules in their "digital twin city" construction, achieving full-process linkage from meteorological early warning to drainage scheduling. In the future, with the deep integration of sponge city, smart pipeline network, and IoT technologies, urban flood control systems will develop towards self-adaptation and autonomy, becoming an important component of smart cities.

III. Ecological River and Lake Safety Supervision and Infrastructure Safety

Under the background of giving equal importance to ecological civilization construction and infrastructure safety, water hazard detection solutions are being widely used in ecological river and lake monitoring, transportation engineering disaster prevention, and hydrogeological risk assessment. For key areas such as mountainous areas, bridges, hydropower stations, and transportation hubs, the system integrates multi-modal monitoring methods such as rainfall, water level, slope displacement, soil moisture content, and video recognition to achieve real-time identification and early warning of potential disasters. Data from China's Ministry of Emergency Management shows that in 2024, there were more than 2,000 high-risk areas for flash floods and landslides nationwide, but the coverage rate of intelligent disaster prevention monitoring was still less than 50%, indicating a huge market potential. In plateau mountainous areas represented by Sichuan and Yunnan, new technologies such as 5G communication, BeiDou positioning, and drone patrols have enabled rapid response and emergency handling at disaster sites. In the future, with the popularization of AI image recognition and edge computing, the system will realize a disaster prevention and supervision mode of "unmanned operation, intelligent identification, and automatic early warning", providing strong protection for ecological security and infrastructure resilience.
