Researchers at Victoria University in Australia say they have developed AccuMM, an automated solution for the long-term monitoring of landslides.
The team notes AcuuMM uses low-cost solar- or battery-powered wireless global-positioning system sensors and a specialized, cloud-based algorithm to calculate the location of each sensor, relative to a fixed-based station.
This system enables daily measurements to be taken at multiple points on a landslide without the need for human site visits. In addition, the researchers say the system has no line-of sight or cabling requirements, and requires no intervention at the site for five years or more.
The researchers ran a pilot test of AccuMM in Taiwan, and now they are trialing the system in areas of Australia where landslides have occurred.
"We can power the wireless network by energy harvesting, which means our system can operate for long duration to meet the monitoring needs of geotechnical engineers," notes Victoria University professor Winston Seah.
