Observations and Analysis of the Horizontal Structure of a Tidal Jet at Deep Scour Holes

Scour in the vicinity of a hydraulic structure may compromise its geotechnical stability or that of nearby structures. Much fundamental research has been dedicated to the understanding and prediction of these processes, in order to enable the efficient design of mitigation measures. While most of these efforts consider laterally uniform flows,...

Sediment transport through the Eastern Scheldt storm surge barrier

The aim of this research is to determine to what extend the scour holes limit the sediment transport through the Eastern Scheldt storm surge barrier and whether or not human adaptations, like sand-nourishments in the scour holes, can have a positive effect on the sediment import. To investigate these scenarios a numerical model (Delft3D) is used...

Scour hole development Maasvlakte 1 & 2: Data analyis and forecast

Model simulations on the basis of uniform (non-graded) sediment reveal a strong overestimation of the scour hole in the area directly to west of Maasvlakte I when compared to the measured scour hole. Data analysis shows that the scour hole developed in a former complex estuarine system. The analysis strongly suggests that erosion occurred...

Concentration and flow velocity measurements in a local scour hole

Flume experiments with small Froude numbers have been carried out to study the concentration field in a local scour hole without supply of sediment load. The measuring results will be used to check the validity of the two dimensional scour model DUCT-SUSTRA. The objective of the experiments was to measure the concentrations at various locations...
