Interface stability of granular filter structures: Desk study

Verheij, H.J. (author), Hoffmans, G. (author), Den Adel, H. (author), Akkerman, G.J. (author), Giri, S. (author)

A desk study has been carried out regarding interface stability of granular filter structures. Actually, the project focuses on two particular aspects: (1) interface stability as function of the thickness of the filter layer consisting of standard armourstone gradings, and (2) interface stability of gravel mixtures with a wide gradation The...

Shear stress concept in granular filters

Hoffmans, G.J.C.M. (author), Den Adel, H. (author), Verheij, H.J. (author)

Scour is a natural phenomenon caused by the flow of water in rivers and streams and occurs as a part of the morphological changes caused by rivers or as a result of man-made structures. For the Dutch Delta Works hydraulic structures were often constructed on fines with loose packing. To guarantee the geotechnical stability of these structures...

Evaluation of recent desk study results on granular filters

Verheij, H.J. (author)

Recently, a number of desk studies have been carried out with respect to the phenomena in and the design of granular filters. These have resulted in some formulas allowing the dimensioning of granular filters. The most important formulas are those developed by Hoffmans based on the shear stress concept of Grass (indicated hereafter as the...

Dichte bekleding op filter, wateraccumulatie onder bekleding bij een storm.

Meijers, P. (author)

Een eenvoudig model is opgesteld om de waterstroming in een filterlaag onder een dichte bekleding tijdens golfaanval te beschrijven. In dit model is de mogelijkheid dat de bekleding lokaal los komt van de ondergrond tijdens golfbelasting meegenomen. Met dit model zijn berekeningen uitgevoerd, zowel met geschematiseerde golfdrukken als met...
