Application Overview

Unmanned aerial vehicles can be used for auxiliary supervision of suspected illegal construction, illegal planting and development and utilization, illegal sand mining and other incidents within the jurisdiction of the water resources project jurisdiction, extracting information on the location and scope of illegal acts, and providing technical support for law enforcement and management. Violations of laws and regulations shall be detected early, stopped early and dealt with early.

Traditional water and soil conservation monitoring techniques cannot meet the requirements of accuracy, timeliness and completeness in production and construction projects. UAV low-altitude remote sensing has the characteristics of high precision, high timeliness and high degree of visualization. It can be used for quantitative detection and evaluation of soil erosion, monitoring and evaluation of soil and water conservation treatment measures, and soil and water conservation monitoring of production and construction projects. UAV remote sensing monitoring has become a new technical means to comprehensively monitor the state of soil and water conservation.

UAV systems play an important role in the field of flood control, drought relief and disaster relief, and can be used for emergency monitoring of landslides, mountain floods, urban floods, and dam failures. The maneuverability and flexibility of the UAV system is especially suitable for emergency tasks, which greatly reduces the risk of emergency responders, and improves the efficiency of handling early warning and disasters. Quickly and accurately carry out aerial photography and damage assessment of the disaster-affected area, and provide rescuers with valuable first-hand information.

UAV can quickly monitor the water resources projects that need to be inspected in real time, and through real-time inspections of upstream and downstream rivers, they can grasp the relevant hydrological conditions such as land inundation caused by the construction of hydraulic structures ASAP. The analysis results of monitoring data obtained by UAV can effectively monitor temporary buildings such as cofferdams, check the safety status of surrounding slopes, and investigate the type and amount of flooded land. Discover relevant signs in time to prevent accidents and ensure the smooth progress of hydraulic structures. At the same time, it provides information for controlling the quality of construction, reducing the impact on the surrounding environment, and improving construction methods.

Barrier lakes are formed by blocking river valleys or riverbeds and storing water after landslides and landslides caused by mudslides or earthquakes. The scale and environment of barrier lake formation are complex, and the blockage is vulnerable to erosion. Once it is destroyed, it is easy to cause secondary disasters with serious consequences. Due to its technical characteristics such as small size and flexibility, rapid maneuverability, and simple maintenance and operation, the UAV can provide efficient on-site investigation and evaluation and dynamic early warning for the distribution and dynamic changes of the barrier lake. It provides the basis for experts’ first-hand information and scientific decision-making on the nature and risk assessment of dammed lakes, and the preliminary investigation and scale estimation for the barrier lake failure plan and the immediate disaster plan for the resettlement of downstream dangerous areas. Make timely monitoring and early warning for risk elimination and failure.

The traditional manual method of visually estimating the ice flood situation relies on the experience. Although simple and reliable, the observation range is small and lacks the grasp of the ice flood information of the entire river channel. Satellite or aerial remote sensing detection method has a large observation range and wide coverage. However, due to the long revisit period of satellites, the remote sensing resolution is low, and it is susceptible to atmospheric interference, the ability to grasp the local details of the river is not strong, and the real-time performance does not meet the demand. UAV telemetry technology has mature applications and practices in many fields such as environmental monitoring and disaster assessment. UAVs are equipped with high-performance sensors of various types, which can remotely monitor river openings, ice jams, ice piles and ice dam distribution, etc., provide a scientific basis for judging the scale and disaster situation of ice floods.
