Weak spots in dikes can be detected quickly and efficiently with geophysical dike research. This can be done from ground level, but also from the air with the help of a drone. Possible applications of geophysical techniques in dike research are:
Seepage (water) detection: each dike allows water to pass through under normal circumstances. If a dike is overloaded by extreme conditions, it will let more water through than normal.
Piping: these are sand tracks in or under the dike, through which a lot of water can flow. As a result, there is a chance that soil will be washed away, weakening the dike.
Detecting presence of and damage caused by muskrats.
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.
