Mountain floods triggered by heavy rainfall are sudden and destructive, threatening lives and property. Traditional early warning systems have incomplete monitoring and delayed responses. Our solution integrates flood risk maps and a targeted warning system to upgrade watershed risk management.
Mountain floods caused by intense or continuous rainfall are sudden, destructive and fast-developing, posing severe threats to lives, property and ecosystems. Traditional monitoring and early warning systems suffer from insufficient coverage, delayed response and inaccurate decision-making. This solution innovatively integrates flood risk maps with the "One Village, One Policy" system to build a closed-loop system: space-air-ground integrated monitoring, intelligent early warning models, multi-channel accurate release and rapid grassroots response, realizing a leap from single-point early warning to watershed risk management.


Dynamic flood risk maps combined with real-time inundation simulation support a household-level early warning and response mechanism, clarifying evacuation requirements and speeding up emergency actions.

A continuously updated population database provides real-time data on population distribution and housing locations, enabling warnings accurate to villages, households and individuals.

3D dynamic display integrates inundation, disaster and shelter information, supporting flood analysis, loss assessment and evacuation planning as a mobile operational tool for grassroots teams.

Regular data updates adjust risk zones and warning thresholds dynamically, aligning defense plans with actual threats and achieving proactive flood prevention.

The system integrates flood risk data of protected zones and rivers, providing a scientific basis for flood control and disaster reduction through spatiotemporal analysis.
Integrates geographic, flood control and socio-economic data. Supports flood scenarios of various return periods, displaying inundation maps, arrival time, duration, water depth and evacuation routes with dynamic simulation.
Simulates flood propagation and dynamic risk evolution in the watershed.
Manages flood analysis and 2D hydrodynamic models, supporting calibration, validation and maintenance for practical applications.




The One Village, One Policy Management System follows a village-town-district-city workflow. Through complete household-level data collection and sharing, it achieves: accurate household-level risk records, targeted mountain flood early warning, real-time evacuation reporting, and automatic mapping of village-level plans, greatly improving mountain flood prevention capacity.





Based on satellite remote sensing data, the platform integrates hazard zones, basic records and 3D models to visualize village and household data efficiently.
One-click evacuation reporting: real-time early warning, automatic evacuation list generation and one-click status reporting.
Dynamic household database: online update and review for risk household information.
Automatic plan generation: unified template, evacuation list and plan mapping for standardized annual preparedness.
