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

The relation between water levels and discharges in the Waal river has been estimated from observations, not finding an effect of Room for the River interventions on water levels.

On the use of large-scale biodegradable artificial reefs for intertidal foreshore stabilisation

A large-scale experiment was conducted on the tidal flats of the Dutch Wadden Sea, by installing biodegradable artificial reefs along 630 m. Waves, sediment dynamics and sediment properties around the structures were monitored over three years.

How grazing management can maximise erosion resistance of salt marshes

We aimed to determine how salt marsh management (i.e. grazing by large vs. small grazers vs. artificial mowing), marsh elevation and marsh age affect soil stability (i.e. soil collapse) and intrinsic lateral erodibility of salt marshes (i.e. particle-by-particle detachment).

Application of geo-statistics and pairwise established CPT-based correlations for line infrastructure

A method to use CPT and laboratory tests to calculate characteristic values, on the basis of pairwise established CPT-based correlations. We illustrate the method in six cases accounting for regional and local variations, failure extent and availability of local CPTs.

Eemdijk full-scale field test programme: ground dike and sheet pile dike failure test

Two similar test dikes were constructed at full scale (5m high, 25m wide, 60m long) to gain better understanding of the failure mechanism and deformations for both dikes, one of which served as a reference for the dike that had an 18m long sheet pile wall was installed.

Eemdijk full-scale field test programme: sheet pile pullover tests

The full-scale pullover tests consisted of 4 sheet pile configurations to gain more insight in the soil-structure interaction and the structural behavior of sheet piles beyond maximum bending capacity.

Impact of the Eemdijk full-scale test programme

This paper describes the rationale behind the test setup and operation of the test programme in relation to the current design codes and guidelines. First the set of knowledge questions to be resolved is considered. These questions gave direction to the type of failure tests, the required instrumentation and the impact of conclusions.

CPT based unit weight estimation extended to soft organic soils and peat

A new correlation is proposed that can be used to estimate the saturated soil unit weight from sands to highly organic soils. Our proposal outperforms other considered correlations. The variation in the estimation is however still considerable and comparable to earlier studies.
