Measuring Bed Exchange Properties of Cohesive Sediments Using Tripod Data

The Krone–Partheniades (K-P) framework has been used for decades to quantify and analyze the sediment exchange at a water–bed interface. Measuring the erosion and deposition parameters that are part of this framework requires time-consuming field observations. Additionally, the erosion parameters are measured independently of deposition...

Modelling self-healing magnetic textures in hydrodynamic bearings

Hydrodynamic bearings can be used to minimise friction, and their load capacity can be improved by texturing the bearing surfaces. However, due to mechanical contact between the surfaces during start and stop, these textures are susceptible to wear. Previously, a new method of creating textures using magnetorheological fluids as lubricant was...

Verification of a Predictive Formula for Critical Shear Stress with Large Scale Levee Erosion Experiment

Apart from the soil erodibility parameter, the critical shear stress is the most important parameter in predicting erosion rates. On the basis of experiments several empirical formulas have already been de-veloped which relate the critical shear stress to soil properties. Based on these findings and supported by new large scale experiments, a...

Effects of water inifltration on soil erodibility

A new flood risk approach for design and testing of primary and secondary flood defence structures in the Netherlands relies on the probability of loss of the water retaining capacity. Determining this probability for levees requires a better understanding of consequences of extreme conditions leading to failure, starting with a study of soil....
