Geological framework for assessing variability in subsurface piping parameters underneath dikes in the Rhine-Meuse delta, the Netherlands

T.G. Winkels, K.M. Cohen, S.M. Knaake, H. Middelkoop, E. Stouthamer - 05/12/2021 - All-Risk
Downstream fining of D50 top sand values is caused by drops in specific stream power. Sediment inheritance, through reworking of pre-deltaic sands causes local variations in D50 top sand values.

Stroomafwaartse verfijning van D50 dekzandwaarden wordt veroorzaakt door dalingen in het specifieke stroomvermogen. Sedimentvererving, door omwerking van pre-deltaïsch zand, veroorzaakt lokale variaties in D50 topzandwaarden.

Initiating and upscaling mussel reef establishment with life cycle informed restoration: Successes and future challenges

Temmink, R.J.M., Fivash, G.S., Govers, L. L., Nauta J., Marin-Diaz, B., Cruijsen, P.P.M.J.M., Reijers V.C., Didderen, K., Penning, E., Olff, H., Heusinkveld, J.H.T., Lamers L.P.M., Lengkeek, W., Christianen, M.J.A., Bouma, T. J. & van der Heide, T., - 25/11/2021 - All-Risk
Life cycle informed restoration enhances mussel bed formation. However, mussel biomass depends on sediment burial. Larger-scale processes resulted in partial burial of the structures. Therefore, optimisation of the structures is required to overcome technical failure at exposed sites.

Numerical investigation of the effects of roughness, a berm and oblique waves on wave overtopping processes at dikes

Chen, W., Warmink, J. J., van Gent, M. R. A., & Hulscher, S. J. M. H. - 24/11/2021 - All-Risk
Introducing a roughness factor to existing empirical formulas leads to better estimates of the flow charac-teristics. We found that the flow characteristics are more sensitive to the variation of the berm width than to the berm level. In order to take oblique waves into account, the 2D numerical model is extended into the 3D model domain. The numerical model computa-tions confirm that the reductive influence factor of oblique waves is dependant on the berm width.
