Modelling of the cross-shore grain size distribution in the intertidal zone

The Building with Nature approach has been gaining ground in hydraulic engineering, increasing the importance of understanding the cross-shore morphodynamic processes. The intertidal zone, where marine and aeolian processes come together, is an important link in the transport of sediment from the sea towards the dunes. The grain size...

The role of algae in fine sediment flocculation: In-situ and laboratory measurements

The precise interactions between organic and inorganic particles in the context of flocculation is an on-going topic of research. The suspended particulate matter (SPM) found in estuaries is composed of both organic and inorganic particles with specific particle size distributions (PSD's). These PSD's are a function of the hydrodynamic...

Modelling study on the three-dimensional neutron depolarisation response of the evolving ferrite particle size distribution during the austenite–ferrite phase transformation in steels

The magnetic configuration of a ferromagnetic system with mono-disperse and poly-disperse distribution of magnetic particles with inter-particle interactions has been computed. The analysis is general in nature and applies to all systems containing magnetically interacting particles in a non-magnetic matrix, but has been applied to steel...

Determination of Spatial Variability in d70 Grain Size Values Using High Density Site Measurements

Research to the failure mechanism piping (internal, backward erosion) in the Netherlands shows that the dikes require costly berms to meet the required safety standards. According to the Sellmeijer piping-formula, the d70 (70%-quantile of the grain size distribution by weight) is an important parameter in the resistance against piping. Therefore...

Analysis of Grain Size Distribution for samples from the North Caspian Sea Basin

The ultimate goal of this project is to identify the controls of the sedimentary systems of the North East Caspian Sea, in order to improve the capabilities for the assessment of the effects of the construction of future installations in the vicinity of Karain and Aktote islands on the coastal dynamics. Additionally, it is desirable to enable...
