As extreme weather events become increasingly frequent, how to detect risks faster, assess hazards more accurately, and carry out emergency rescue more efficiently has become a critical challenge in flood control work.On May 31, 2026, the Hunan Province Reservoir Flood Control and Emergency Rescue Drill was successfully held at Wuchuan Reservoir in Changsha County. The drill was jointly organized by the Hunan Provincial Department of Water Resources and the Changsha Municipal People’s Government.

Wuhan Tianbaonet Technology Co., Ltd. was invited to showcase its core surveying and mapping equipment at the on-site technology exhibition area. With its advanced 3D laser scanning technology, the company helps address the digital gaps in water conservancy emergency surveying, supporting Hunan in building an integrated “Sky–Land–Water–Engineering" intelligent monitoring and perception network, and demonstrating its commitment to flood prevention and disaster mitigation through geospatial innovation.

The drill adhered to the principles of “realistic, professional, and technology-driven" operations. It simulated multiple complex emergency scenarios caused by continuous heavy rainfall, including dam seepage, culvert leakage, slope instability, and communication failure.

In response to sudden disaster conditions, various emergency rescue teams and modern equipment were rapidly deployed. Through patrol monitoring, hazard mitigation, emergency communication, and personnel evacuation, the exercise comprehensively tested emergency response capabilities and coordinated rescue operations.

Unlike traditional approaches that rely heavily on manual inspection and experience-based judgment, this drill widely integrated intelligent and digital equipment, fully demonstrating the new achievements of technology-enabled flood prevention and disaster mitigation.

Traditional reservoir inspection faces several challenges:

• Large inspection areas with low efficiency
• Monitoring blind spots in complex terrain
• Manual data recording with slow sharing
• Lack of intuitive visualization of evolving risks

The application of 3D laser scanning technology provides a new solution to these challenges.At the technology exhibition area of the drill site, Tianbaonet’s handheld 3D laser scanner received strong recognition from water resources professionals and attending leaders. It is well-suited for comprehensive emergency surveying in water conservancy engineering:

• Rapid on-site data acquisition
  The device can quickly capture 3D data of dams, slopes, culverts, and surrounding environments, generating high-precision real-scene models in a short time.
• Accurate measurement for scientific decision-making
  Based on high-precision point cloud data, it enables precise analysis and measurement of cracks, settlement, deformation, and erosion areas. This transforms risk assessment from experience-based judgment to data-driven decision-making, providing a reliable foundation for expert remote consultation and emergency command.
• Portable and flexible for complex environments
  With its lightweight design, the device can be rapidly deployed in dams, spillways, culverts, slopes, and other complex areas, enabling true “easy to carry, easy to access, fast to scan, and highly accurate" operations.

During the drill, a range of advanced technologies were showcased, including vegetation clearing robots, underwater inspection robots, UAV patrol systems, intelligent monitoring devices, and Tianbaonet’s 3D laser scanning equipment.

Together, these cutting-edge technologies formed an integrated “Sky–Land–Water–Engineering" intelligent monitoring and perception system, driving flood control from traditional reactive response toward proactive early warning and precise prevention, enabling:

• Sky-based coordinated monitoring
• Ground intelligent inspection
• Underwater risk detection
• Digital engineering management

As a leading surveying and geospatial information products and solutions provider in China, Tianbaonet has always been committed to technological innovation in support of national infrastructure development and industry digitalization.The company continues to advance the application of 3D laser scanning and high-precision spatial measurement technologies in water conservancy disaster prevention and mitigation. Participation in this Hunan Reservoir Flood Control and Emergency Rescue Drill not only served as a real-world validation of product performance, but also demonstrated the company’s commitment to social responsibility and its contribution to national disaster prevention systems.

With the increasing frequency of extreme weather events, flood prevention and disaster mitigation face new challenges and higher demands for technological support.In the future, Tianbaonet will continue to leverage its expertise in geospatial technologies, continuously optimize its 3D laser scanning equipment, and expand industry solutions for emergency water conservancy surveying, reservoir health monitoring, and digital modeling of levees and embankments.

By delivering smarter, more precise, and more reliable geospatial technologies, Tianbaonet is committed to empowering water conservancy flood control efforts worldwide and safeguarding lives, property, and the stability of rivers and waterways.
