Water storage, hydropower, and recreation are provided by the basins. Adding a reservoir changes a landscape's geological conditions and can lead to new and unpredictable risks. Maintaining infrastructure and public safety are dependent on understanding the factors that lead to the slide.
A new fiber-optic nerve system was introduced in the study. The authors designed, implemented, and installed their FONS to monitor the ancient Outang landslide in China's Three Gorges. Real-time, high spatial resolution data is provided by the system.
Each monitored variable has its own fiber-optic cables deployed. There is a 4-inch (100- millimeter) hole that extends more than 40 meters below the surface. The array can be used to transmit metrics on the ground to a data server at the surface.
The rear slope's main and secondary slip surfaces were confirmed. They found that short, high-intensity rains had a greater effect on landslide mechanics than steady rains. There was a discrepancy between the relationship between the two.
Integrated hazard monitoring is possible with the new system. The underground detection system can offer critical insights into the causes and mechanisms of the landslide. Satellite, aerial, and surface sensors could be combined to look atgeohazards
