Van de Sande, S.A.H. (author), Uijttewaal, W.S.J. (author), Verheij, H.J. (author)Granular filters are used for protection against scour and erosion of base material. For a proper functioning it is necessary that at the interfaces between the filter structure, the subsoil and the water flowing above the filter structure no material will be transported. Different types of granular filters can be distinguished, this paper...conference paper 2014

Steenstra, R.S. (author)For the design of granular bed protections often a stability parameter is used. The stability parameter represents the forces that are acting on the stones and is used to predict the response of the bed to these forces. Existing parameters are often derived for a limited range of application. When the parameter is used outside this range, the...master thesis 2014

Roelse, F.P. (author)In the last decades shipping has increased significantly, resulting in larger ships with an increasing power in bow thrusters. Due to this increasing power, the hydraulic loads at bottom protection near quay structures has also increased, making a traditional bed protection more expensive. Therefore an alternative design method is suggested in...master thesis 2014

Verheij, H.J. (author), Hoffmans, G. (author), Dorst, K. (author), Van de Sande, S. (author)Granular filters are used for protection of structures against scour and erosion. For a proper functioning it is necessary that the interfaces between the filter structure, the subsoil and the water flowing above the filter structure are stable. Stability means that there is no transport of subsoil material through the filter to the water above...conference paper 2012

Hoan, N.T. (author), Stive, M.J.F. (author), Booij, R. (author), Hofland, B. (author), Verhagen, H.J. (author)This paper presents the results of an experimental study on stone stability under nonuniform turbulent flow, in particular expanding flow. Detailed measurements of both flow and turbulence and the bed stability are described. Than various manners of quantifying the hydraulic loads exerted on the stones on a bed are extensively reviewed and...journal article 2011

Hoan, N.T. (author)Despite the fact that many studies on the stability of stones in bed protections under flowing water have been conducted, our knowledge is still far from advanced and reliable. Issues like how to quantify the hydraulic loads exerted on the stones on a bed and the associated stability of the stones are still central and most challenging in stone...doctoral thesis 2008

Hughes, S.A. (author)A 1-to-25 scale physical model of a typical cross section of the levee along the Mississippi River Gulf Outlet (MRGO) was con-structed at the U.S. Army Engineer Research and Development Centers Coastal and Hydraulics Laboratory in Vicksburg, MS. The purpose of the physical model was to obtain hydrodynamic measurements of unsteady flow...report 2008

Hoan, N.T. (author), Booij, R. (author), Hofland, B. (author), Stive, M.J.F. (author), Verhagen, H.J. (author)The current research is aimed at finding a proper relation between flow forces acting on the bed and the bed response. To this end, experiments were carried out in which both the bed response (quantified by a dimensionless entrainment rate) and the flow field (velocity and turbulence intensity distributions) are measured. The three available...conference paper 2007

Hoan, N.T. (author), Booij, R. (author), Hofland, B. (author), Stive, M.J.F. (author), Verhagen, H.J. (author)The current research is aimed at finding a dimensionless stability parameter for non-uniform flow in which the effect of turbulence is incorporated. To this end, experiments were carried out in which both the bed response (quantified by a dimensionless entrainment rate) and the flow field (velocity and turbulence intensity distributions) are...conference paper 2007

Hofland, B. (author)Layers of stone or rock are often applied around hydraulic structures to protect the sand bed from scouring. Determining the size of the rocks is complicated by the fact that the flow over a bed protection usually is non-uniform. This thesis describes two experimental series in which the stability of a single stone under non-uniform flows is...doctoral thesis 2005

Van Breugel, R.H. (author), Ten Hove, T.D. (author)In een stroomgoot is modelonderzoek gedaan naar de steenstabiliteit van een bodembescherming bij waterbouwkundige konstrukties. Onderzoek naar de grootte en lokatie van de stroomaanvallen kan leiden tot belangrijke besparingen in de kosten van aanleg en onderhoud van bodembeschermingen. Onderzoek is gedaan naar konstrukties die de stroming...master thesis 1995

Grote, W. (author)Stability of rock on horizontal bottoms and steep slopes subjected to wave attack has been a subject of investigation in the past. But the stability of rock on gentle slopes has not been investigated systematically. The objective of this research is to investigate the relations between the different variables involved. A possible application is...master thesis 1994
