High water levels and floods increasingly show the importance to properly monitor the condition of our dikes. With geophysical research, deformations and weak spots in a dike can be detected quickly and efficiently. This can be done from ground level but also from the air using a drone.
Geo-electrical measurements Geo-electrical measurements (resistance measurements) are an electrical research technique that determines the resistance of the subsurface in a non-destructive way. This technique can be used in dike inspections if the subsurface has to be accurately mapped in order to record geological structures with a high resistance or a resistance that deviates from the surroundings. The depth range of the measurements varies from a few meters to a depth of more than 500 meters.
Dike inspections with Drone technology
T&A Survey Drone Services performs dike inspections with a drone equipped with various techniques such as infrared (IR) thermography, LiDAR and photogrammetry. Read more about Dike inspections with drones.
