Bogers, P. (author)At present no computer model is available that can determine the stability of an inlet or what will happen to the stability after some adjustment of the inlet. This study has the objective to develop a simple model th at combines all major parameters in order to determine the stability of an inlet and the effects of adjustments on the stability...master thesis 1991

Gerding, E. (author)In this report an analysis of data from a series of tests is presented on the stability of the toe structure of rubble mound breakwaters. The existing knowledge on toe stability and the influence of all governing parameters in the existing knowledge is reviewed. The tests which were performed for the present research are treated extensively. The...master thesis 1993

Coopmann, S.W.M. (author)In Nederland wordt het steeds moeilijker om bouwdokken, voor het vervaardigen van afzinkelementen van een afzinktunnel, aan te leggen. Daarom wordt uitgeweken naar reeds bestaande bouwdokken, en worden de tunnelelementen over langere afstanden en ook over zee vervoerd. De krachten en momenten die door de golfbelasting, tijdens transport over zee...master thesis 1996

Nuijten, G.A. (author)For tunnels it is not only important, how the tunnel and the surrounding rock behave during the life time of the tunnel. It is also very meaningful to understand how the tunnel is behaving, while it is under construction. The basis for this thesis is to understand, how the tunnel behaviour, concerning deformation and stability, is for different...master thesis 1997

De Boer, G.M. (author)Experimental research on the stability of bed protection and transport of stones on such a bottom protection. Investigated were the effects of duration and magnitude of the load, the shape, and placing density of the stones.master thesis 1998

De Haas, M.J. (author)After consulting the "Department of Environment" in Australia it was suggested that an extensive generic study about Tidal Inlets on Littoral drift shores gives them an insight in the processes at work and also the possibilities to improve the stability in order to make tidal inlets suitable for safe navigation. This report describes the most...master thesis 1999

De Heij, J. (author)The first one who studied the problem of armour layer stability was Iribarren (1938). Iribarren derived stability criteria that were based on the acting physical processes on the slope of a structure. In the stability criteria of Iribarren only the influence of a few structural and hydraulic parameters were taken into account. In 1988 Van der...master thesis 2001

de Ruijter, R. (author)Downstream of man-made hydraulic structures, bed protections made of granular material are often used to prevent erosion of the bottom. The stones in the top layer of such granular filters must be able to withstand the hydraulic forces. Probably the best-known formula that is used to determine the stability of granular bed material is the design...master thesis 2004

Beekx, R.H.P.A. (author)South Korea is reclaiming land by constructing dams and polders. The large tidal differences along the Korean coast make building these dams a challenging job. One of the solutions in South Korea to cope with the high flow velocities in closure projects is to apply sack gabions. These are steel nets with rocks inside them that weigh up to 3 tons...master thesis 2006

Mertens, M. (author)In VAN GENT [2004] graphs were presented in which the datasets of VAN DER MEER [1988] and VAN GENT ET AL. [2003] were compared, but in this comparison a number of parameters were not correctly transformed into a comparable format. In this M.Sc. thesis after an extensive analysis to the datasets all parameters of the datasets of Van der Meer were...master thesis 2007

Frens, A.B. (author)The main objective of this research was to assess the impact of different placement methods, with different packing densities, on the stability of double layered Antifer-block armour layers. This was done by experimental research in the wave-flume of the Fluid mechanics laboratory of the Faculty of Civil Engineering and Geosciences at Delft...master thesis 2007

De Rover, R.A. (author)At breakwater and seawall projects at Port St Francis and Scarborough breakage of single layer interlocking armour units was observed. It is generally assumed that breakage of single layer armour units has a significant negative effect on the hydraulic stability of a rubble mound breakwater. The significant decrease of interlocking capacity and...master thesis 2007

Dijkstra, O.P.J. (author)In coastal regions where the land is sensitive to erosion, but also for harbours and ports, numerous types of defensive structures have been developed to protect it from the effects of incident waves. More recently breakwaters have been constructed which combine the stability characteristics of a conventional two-layered uniform sloped...master thesis 2008

Sveinbjornsson, P.I. (author)A major part of the breakwaters constructed in the world are the so-called conventional rouble mound breakwaters, which consist of a core, a filter layer and a heavy armour layer. An alternative to the conventional rouble mound breakwater is a berm breakwater. Berm breakwaters have mainly developed in two directions over the last couple of...master thesis 2008

Oosthoek, J. (author)Gabion mattresses consist out of a steel wire grid in which fill material is retained. The advantage of these constructions is that the individual particle stability is no longer of importance. The containing function of the grid results in the effect that the fill material starts to behave as a group. Next to that the mattresses are all...master thesis 2008

Aanhaanen, J.A.M. (author)The Master’s thesis has focussed on the stability of a facetted shell structure. The research contributes to a Ph.D. research currently carried out at the Technical University of Denmark (DTU), which investigates the possibilities to design and build a shell structure from flat glass panels. The structure is a so-called plate (facetted)...master thesis 2008

Bos, J.A. (author)Installed wind power world wide is increasing rapidly. The increase in wind power in the European electricity grid is expected to have its impact on the system behaviour. A European study, European Wind Integration Study (EWIS), was thus set up to study the impact of wind power. This thesis was carried out in parallel with EWIS and overlaps at...master thesis 2008

Zimmermann, N. (author)The Westerschelde estuary in the South-West of the Netherlands displays two meandering flood and ebb channels separated by shoals. The system of flood, ebb channel and shoal between two channel crossings form a morphological cell. The stability of the serial cell system formed by the Westerschelde is important for the navigation route to the...master thesis 2009
