Determination of REV and Effective Properties of Fluvial Depositional Systems: A feasibility study using 3D FLUMY models

Fluvial reservoirs are difficult to model due to the high permeability contrast between the sandstone bodies and the overbank deposits and the complex geometry of the permeable (sandstone bodies) and impermeable zones (overbank deposits). A set of fluvial meandering models has been generated using FLUMY. The models represent a range of Net-to...

Permeability of layered glass bead samples: Effect of grain size mixing in layer boundaries

Geotechnical projects are successful when there is a lot of knowledge about the soil implemented in safe sustainable solutions. Existing models of hydraulic flow in soils need to be tested and confirmed again and again to make sure it’s trustworthy. With the use of three-layered samples containing 1mm and 3mm glass bead sizes a simplified model...

The use of Elastocoast in breakwater research

In this report will be explained how breakwaters can be made with the use of Elastocoast, a sort of glue. This makes it possible to fix the individual rocks, and allows repetitive tests possible with exactly the same layer properties. We made six samples of breakwater rock layers, made with Elastocoast and stones, which can be placed and tested...

Gaining a Porosity- Permeability relation by using the sandstone cuttings from the 'Delft Aardwarmte Project (DAP)'

Efficiency is becoming nowadays more and more relevant. The more efficient people can perform tasks, the better it is. This is also the case for doing research. The main purpose of this thesis is to gain a permeability- porosity relation of the Delft Sandstone using cuttings, that were gathered during exploration drilling. Cuttings are irregular...

A comparison of overtopping behaviour over a permeable and impermeable crest: An insight into overtopping discharges and intensities

The purpose of this report is to investigate the differences in overtopping characteristics over the crest of a rubble mound breakwater when the crest is made either impermeable or permeable. Among numerous characteristics that are effected by a modification in the permeability of the crest, this report looks specifically into three separate...
