Miedema, S.A. (author)In dredging, trenching, (deep sea) mining, drilling, tunnel boring and many other applications, sand, clay or rock has to be excavated. The productions (and thus the dimensions) of the excavating equipment range from mm3/sec - cm3/sec to m3/sec. In oil drilling layers with a thickness of a magnitude of 0.2 mm are cut, while in dredging this can...book 2015

Pham, P.V. (author), van der Star, WRL (author), van Paassen, L.A. (author), Ye, G. (author)Rice husk ash is a promising pozzolanic material produced from rice husk burning and has significant potential a sustainable replacement for cement in construction and ground improvement applications. In this study the effect of burning conditions on the ash reactivity and its potential for soil stabilization applications have been investigated...book chapter 2015

Li, J. (author), Menenti, M. (author), Mousivand, A. (author), Luthi, S.M. (author)Playas in endorheic basins are of environmental value and highly scientific because of their natural habitats of a wide variety of species and indicators for climatic changes and tectonic activities within continents. Remote sensing, due to its capability of acquiring repetitive data with synoptic coverage, provides a unique tool to monitor and...journal article 2014

Milioritsas, M. (author)In this study a deep tunnel excavation in the Boom Clay (BC) formation, in the context of constructing a repository for the deep geological disposal of radioactive waste in the Netherlands, is investigated by means of numerical modelling. First the selection of a constitutive soil model, that captures adequately the known aspects of the...master thesis 2014

Ensing, M.C. (author)This research aims to provide an understanding of the behaviour of co-disposed coarse (sand) and fine (clay and silt) tailings when discharged into an onshore dredge pond, and the dependence of that behaviour on the sediment composition. This understanding contributes to the ultimate goal of finding a method by which fine tailings can be...master thesis 2014

Zhao, G. (author), Visser, P.J. (author), Peeters, P. (author)Embankment breaching is a composite process coupled by hydraulic processes and sediment transport processes. Erosion is the link in the interaction between breach flow and embankment material. Surface erosion starts in the initial breach phase and triggers the initial damage of the embankment. As the surface erosion develops completely, the...report 2014

Miedema, S.A. (author)This book gives an overview of cutting theories. It starts with a generic model, which is valid for all types of soil (sand, clay and rock) after which the specifics of dry sand, water saturated sand, clay, rock and hyperbaric rock are covered. For each soil type small blade angles and large blade angles, resulting in a wedge in front of the...book 2013

Liefferink, D.M. (author)This version of the thesis only covers the literature study. The results analysis and conclusion of the thesis are confidential. Pipelines in arctic waters are at risk of being damaged by gouging ice masses. To protect these pipelines, they can be buried in trenches. When trenching in arctic clayey soil, sub sea permafrost can be encountered....master thesis 2013

Meijer, G.J. (author)In this thesis a method is developed to regain the geotechnical behaviour of undisturbed quick clay by reconstitution of remoulded natural quick clay samples. Quick clay is characterised by a high sensitivity; the ratio between the undisturbed and remoulded strength is very high. Because of the high water content they behave fluid-like after...master thesis 2012

Stanier, S.A. (author), Hu, P. (author), Cassidy, M.J. (author)This paper demonstrates the use of a geotechnical drum centrifuge in the calibration of a model to predict the peak punch-through penetration (qpeak) resistance of a spudcan on sand overlying clay. A series of loose sand overlying clay tests was performed and combined with an existing database of tests performed on dense sand overlying clay. The...conference paper 2012

Zhao, G. (author), Visser, P.J. (author), Vrijling, J.K. (author)This paper describes the hydrodynamic erosion process of undisturbed clay due to the turbulent flow, based on theoretical analysis and experimental results. The undisturbed clay has the unique and complicated characteristics of cohesive force among clay particles, which are highly different from disturbed clay and non-cohesive sand. Based on...conference paper 2011

(author)Several robotic exploration missions will travel to Mars during this decade to investigate habitability and the possible presence of life. Field research at Mars analogue sites such as desert environments can provide important constraints for instrument calibration, landing site strategies and expected life detection targets. We have...journal article 2011

De Visser, M.M. (author)Environmental awareness and sustainable development have been popular themes over the last few years. To improve dikes along the estuaries in Zeeland (The Netherlands) where a high foreland with natural areas of salt marshes is present, alternatives to stone revetments are examined. From a natural and aesthetic point of view, a slope covered...master thesis 2007

Zhu, Y. (author)Numerous flood disasters occur every year worldwide, mostly resulting from failure of dikes, some with catastrophic outcomes. Examples are the dike failures along the Yangtze River in China in 1931 due to heavy rainstorms and those in the Netherlands in 1953 due to a storm surge at the North Sea. Both floods induced many deaths and enormous...doctoral thesis 2006

Vavrina, L. (author)Erosion processes are divided in two parts, whereas first process is detachment process and second process is transport of detached soil. The main function of grass cover is to avoid detachment. Therefore certain strength is necessary to execute this assignment. Resistance of grass covers are affected by several parameters. The influencing...master thesis 2006
