Improving dike reliability estimates by incorporating construction survival

van der Krogt, M. G., Schweckendiek, T., & Kok, M. - 01/01/2021 - All-Risk
The approach is exemplified for a range of typical dikes and for a case study of a full-scale test embankment. The main result is that the reliability can increase significantly, especially for dikes on soft soil blankets.

Value of information (VoI) of combinations of proof loading and pore pressure monitoring for flood defences

van der Krogt, M. G., Klerk, W. J., Kanning, W., Schweckendiek, T., & Kok, M. - 18/12/2020 - All-Risk
We calculate the expected value of extra information obtained from proof loading and monitoring. The additional information improves failure probability estimates for slope stability.

Rivierbodemdynamiek meenemen in het ontwerp van maatregelen

A.J. Paalberg, Robert Pepijn van Denderen, Ralph Mathias Johannes Schielen, Dionysius C.M. Augustijn - 01/10/2020 - RiverCare
In the Dutch Waal river, the bed topography of the navigational channel is measured bi-weekly. In a so-called TKI-project (cooperation between Rijkswaterstaat, HKV and Twente University) we use this data to link morphological changes to specific interventions in the river. This is not a straightforward as it may seem, because the morphological changes are the sum of small scale changes due to e.g. the presence of groynes, medium scale changes coming from the intervention and large scale changes coming from engineering measures in the (far) past to which the profile is still adjusting. A so-called wavelet analysis can be used to disentangle these different scales and enables us to focus only on the morphological changes due to the intervention. This improves river operations and maintenance and in the future also to facilitate the planning of new measures to minimize morphological impact.
