Dijkstra, S.D. (author)The graduation thesis focuses on providing insight in the consequences of subsiding ground on soil anchors. With the years, the bars of an anchored sheet pile walls for example, can be unfavourably loaded due to subsiding soil. As a result of these lateral loads, the bar will deform and elongate, causing the stresses to increase. The...master thesis 2015

Dijkstra, Y.M. (author)Numerical modelling for environmental flow applications, such as for rivers, lakes, estuaries and coastal flows, faces a trade-off between the numerical accuracy and the required computation time. This trade-off results in grids which typically contain 10 to 100 layers in the vertical direction. Such a grid resolution poses severe limitations to...master thesis 2014

Dijkstra, J. (author), Gaudin, C. (author), White, D.J. (author)To investigate the differences in failure mechanisms beneath vertically loaded shallow foundations on silica and carbonate sands by way of particle image velocimetry analysis, 1g and centrifuge model tests have been performed. A comparison of silica and carbonate sand behaviour at low stresses and low initial soil density was made possible by 1g...journal article 2013

Yuan, J. (author), Hicks, M.A. (author), Dijkstra, J. (author)Electro-osmosis consolidation is an innovative and effective ground improvement method for soft clays. But electro-osmosis is also a very complicated process, as the mechanical behaviour, and hydraulic and electrical properties of the soil are changing rapidly during the treatment process; this makes electroosmosis hard to describe and simulate....conference paper 2012

Dijkstra, J.T. (author)Aquatic plants –or macrophytes- are an important part of coastal, estuarine and freshwater ecosystems worldwide, both from an ecological and an engineering viewpoint. Their meadows provide a wide range of ecosystem services: forming a physical protection of the shoreline, enhancing water quality and harbouring many other organisms. Unfortunately...doctoral thesis 2012

Dijkstra, J.T. (author), Uittenbogaard, R.E. (author)Aquatic vegetation has an important role in estuaries and rivers by acting as bed stabilizer, filter, food source and nursing area. However, macrophyte populations worldwide are under high anthropogenic pressure. Protection and restoration efforts will benefit from more insight into the interaction between vegetation, currents, waves and...journal article 2010

Dijkstra, J. (author), Broere, W. (author)The current paper re-introduces the photoelastic measurement method in experimental geomechanics. A full-field phase stepping polariscope suitable for geomechanical model tests has been developed. Additional constraints on the measurement and mechanical setup arising from geomechanical test conditions are outlined as well as the opportunity to...journal article 2010

Dijkstra, J. (author)This thesis introduces two different types of physical model tests to investigate the stress and density change in the soil during installation of a jacked pile as well as two numerical modelling approaches to model the same process in a finite element code capable of large deformations.doctoral thesis 2009

Dijkstra, J.T. (author)Seagrasses are a valuable but threatened part of coastal systems. To aid restoration attempts, a model has been made to study the effect of such flexible aquatic vegetation on flow and sediment transport. Because this model needs to be tested against field results, a field experiment was undertaken around an eelgrass meadow in Dinard, France....conference paper 2009

Dijkstra, J.T. (author)Worldwide, aquatic vegetation is important for the physical and ecological condition of coastal areas. Unfortunately, this vegetation (e.g. seagrasses) is also under pressure due to human activities. Protection and restoration are cumbersome, particularly because the complex relations between vegetation and its environment are not yet well...conference paper 2008

Dijkstra, A.J. (author)In 1885 the race for the skies was initiated with the construction of the Home Insurance Building in Chicago, world’s first true skyscraper. Since the turn of the 1990’s, Asian countries have started to get involved as well in the race for the skies and have even become the leading contestants of today. Driven by their fast economic growth these...master thesis 2008

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

Dijkstra, J.T. (author)By changing flow patterns and sediment transport, aquatic vegetation can affect the development of estuarine bed topography. Besides, since the sediment transport also determines the amount of light available for photosynthetic growth, the presence of vegetation can also affect its own development. This selfsupporting interaction should be taken...conference paper 2007

Dijkstra, J.T. (author), Uittenbogaard, R.E. (author), Stive, M.J.F. (author)In many areas around the world, there is a large interest in the protection and restoration of aquatic vegetation, like eelgrass (Zostera marina), but little is known about the interaction of such vegetation with its environment. To improve this knowledge, a model has been developed that simulates this interaction between highly flexible...conference paper 2006
