Geophysical tomography as a tool to estimate the geometry of soil layers: Relevance for the reliability assessment of dikes

J. Chavez Olalla, T. G. Winkels, D. J. M. Ngan-Tillard, T.J. Heimovaara - 05/09/2021 - All-Risk
A combined approach to estimate the geometry of soil layers is presented. The approach combines local point data, i.e. data obtained from a CPT or a borehole log, and geophysical tomography in a universal cokriging framework.

Een gecombineerde benadering om de geometrie van bodemlagen te schatten wordt voorgesteld. De aanpak combineert lokale puntgegevens, d.w.z. gegevens verkregen uit een sondeerapparaat of een boorgatlog, en geofysische tomografie in een universeel co-kriging raamwerk.

Formulating wave overtopping at vertical and sloping structures with shallow foreshores using deep-water wave characteristics

Lashley, C. H., Van der Meer, J., Bricker, J. D., Altomare, C., Suzuki, T., and Hirayama, K. - 31/08/2021 - All-Risk
Accurate estimates of wave height and period at the structure toe often proves difficult and requires the use of either physical modeling or high-resolution numerical wave models. Here, we follow Goda's method to establish an accurate prediction by directly incorporating the foreshore slope and the relative water depth at the structure toe.

Formulating wave overtopping at vertical and sloping structures with shallow foreshores using deep-water wave characteristicsn

Lashley, C. H., Van der Meer, J., Bricker, J. D., Altomare, C., Suzuki, T., and Hirayama, K. - 31/08/2021 - All-Risk
Nauwkeurige schattingen van golfhoogte en periode bij de constructieteen blijken vaak moeilijk en vereisen het gebruik van fysieke modellering of numerieke golfmodellen met hoge resolutie. Hier volgen we de methode van Goda om een nauwkeurige voorspelling vast te stellen door de vooroeverhelling en de relatieve waterdiepte bij de constructieteen direct op te nemen.

Flood risk reduction by parallel flood defences

Marijnissen, R., Kok, M., Kroeze, C., & van Loon-Steensma, J. - 01/08/2021 - All-Risk
Double dikes should be assessed using the transmitted loads of parallel defences rather than the failure of individual defences. The case study of this parallel defence consists of a low dike landward of a tall dike at the coast that, although designed with multi-functional purpose via a culvert, has a negligible improvement in flood protection.

Flood risk reduction by parallel flood defences

Marijnissen, R., Kok, M., Kroeze, C., & van Loon-Steensma, J. - 01/08/2021 - All-Risk
Dubbele dijken moeten worden beoordeeld aan de hand van de overgedragen belastingen van parallelle keringen in plaats van het bezwijken van individuele keringen. De casus van deze parallelle verdediging bestaat uit een lage dijk landwaarts van een hoge dijk aan de kust die, hoewel ontworpen met multifunctionele bestemming via een duiker, heeft een verwaarloosbare verbetering van de bescherming tegen overstromingen.

Multidecadal Analysis of an Engineered River System Reveals Challenges for Model-Based Design of Human Interventions

Berends KD, Gensen MRA, Warmink JJ, Hulscher SJMH - 14/07/2021 - RiverCare
Models predict water level decrease, but measurements are too uncertain for now. This reveals a challenge for validation model predictions of human intervention
