Find the bump in the road
Visually monitoring the susceptibility of hundreds of km of road network to geohazards such as slope instability is slow, expensive, subjective and potentially dangerous.
In a pilot study of the Cyprus road network using InSAR analysis, a number of geohazards were pinpointed quickly and objectively. This included at Petra tou Romiou where repeated pavement resurfacing failed to solve a road cracking problem. InSAR identified the larger scale mass movements causing the cracking which led to measures being taken for a more permanent solution.
Network-wide visual geohazard susceptibility surveys are slow, subjective and potentially dangerous.
A network-wide InSAR analysis and landslide susceptibility mapping in GIS quickly pinpointed the most susceptible locations.
Greater insight was gained at one location of repeated pavement resurfacing that led to a more permanent solution.
