With the current climate change we see that droughts are increasing in intensity and frequency. In addition to other hydrological and agricultural impacts, primary water defenses also suffer. Research has shown that drought has a negative impact on the stability and hence safety of peat dikes in particular. Because a large part of the Netherlands lies below sea level, it is very important to pay attention to this problem. One of the consequences of persistent drought is the occurrence of cracks at the surface of peat dikes.

In this research, Shaniel Chotkan (specialist geotechnics at ABT) used inspection data to set up a data-driven model in which precipitation data and soil data, among others, are used to predict the cracking. If the occurrence of cracks can be predicted, this information can be used to get ahead of failure mechanisms, thus ensuring water safety. The research is a step toward raising awareness of the water safety implications of drought, but much remains to be done.
