Soil creep to be monitored remotely using ICT

Описание: 실내에서도 땅밀림 현상 대응할 수 있어", ICT기술로 예측

As in monsoon seasons of previous years, this year mud has been washed down mountains and onto homes and highways caused by the continuous rain.
Soil creep, which is the downward progression of soil down a low-grade slope, was hard to predict, unlike landslides.
However, progress has been made by national researchers in developing a soil creep prediction system.
Cha Yun-kyung has more.

This is near Tohamsan Mountain in Gyeongju, 2 kilometers away from Seokguram Grotto.
There is a depression in the center of the mountain.
Soil creep and landslides appear similar, but there is a distinction between them.
A landslide happens all of a sudden while soil creep is slow and consistent bringing the risk of recurrent earth movements.
There are distinct differences among their geological features, soil consistency, and moving speed.
Most earth movements that occur in mountainous areas of South Korea are likely to be landslides, which occur on steep slopes of 20 to 40 degrees.
Recently, soil creep has been observed on gentle slopes of less than 20 degrees.

National researchers have made progress on a prediction system that will notify them of soil creep in its early stages.
The research team installed various censors, such as, wire extensometers, groundwater gauges, and displacement meters for structures, that are connected via wired and wireless systems to a central monitoring station.
While existing landslide prediction is focused on shallow collapses of land, the soil creep system monitors not only surface layers but also deep underground.
The system can remotely predict the emergence rate and extent of soil creep through the sensors, also incorporating GPS, without the need for the physical presence of researchers.
Another strength of the system is that it can be used regardless of the weather.

"While humans had to make physical measurements in the past, the remote system allows us to check on the spot information through ICT with values observed by the sensors."


More than 60 percent of cases of soil creep are initiated by artificial changes to the landscape such as the building of roads or industrial complexes.
The research team plans to monitor soil creep nationwide by installing remote systems in mountainous regions across the country.
