DETERMINATION OF DIKE STRENGTH USING REMOTE SENSING
The strength of water defences has traditionally been assessed using numerical models backed up by field observations. Full-surface measurement using remote sensing with automated data interpretation and processing can compensate for the main drawbacks of the traditional approach.
This project will look at whether a combination of various remote sensing images can provide adequate information about the safety of water defences. The challenge here is to use indirect measurements on the surface to establish a picture of the processes going on in the dike.
The new method has three major benefits: physical access to the location is no longer required, interpolation is no longer needed between discreet measurement points and remote sensing images can be recorded and processed very quickly.
Full-surface measurements with remote sensing can be used to set up the dike and sub-surface model, but they can also be used as an inspection tool when there is a heightened flood alert. Discrepancies with respect to the average situation and explicitly dangerous weak zones can, in this way, be identified simply.
