This experiment looks into the question of whether using measurement and sensor technologies form an addition to the regular visual inspection of dikes and can thus predict stability problems in good time. A controlled dike breach was brought about on 27 September 2008.

The test dike for the macro stability experiment was equipped with a wide range of measurement equipment. The analysis of the measurement results shows that movement and deformation in the dike are variables that predict a dike breach well in advance. Deformation took place as far as 42 hours prior to the actual breach of the test dike, precisely at the position where the dike actually collapsed. The sensors proved to support each other in the measurements carried out to detect premature subsidence in the dike.
