S. Korea uses drones to monitor dams, prevent floods Updated: 2021-12-07 08:13:33 KST

South Korea has recently demonstrated a newly-developed water management and surveillance system using high-tech drones.
The government-funded project was launched following the nationwide floods that damaged some eighty-four-hundred households across 17 cities and provinces in August last year.
The project leaders have pointed to ineffective management of water levels at the dams and a lack of inspections in local rivers as the main causes.

"As this area sustained heavy flood damage, various fourth industrial technologies are needed to effectively and scientifically manage the water."

Developers say the drones will be dispatched to inspect and monitor water levels and provide essential information in real time.
The gadgets also use a heat-tracing technique to detect the presence of people who might be in dangerous areas and can send out evacuation warnings.
The drones are also programmed to automatically return to the compound in case of adverse weather.
They are also designed to float on water for over thirty minutes if unable to fly.

"They are almost ready to be deployed right away. But there are some restrictions over what's called "beyond visual line of sight." So if the authorizations are made they can be used."

The developers say the drone system will first be implemented for a test run at Seomjin River in Jeollanam-do Province before being expanded to other regions once further improvements are made.
