Eltayieb, M.F.M.I. (author), Werthmüller, D. (author), Drijkoningen, G.G. (author), Slob, E.C. (author)Delft geothermal project (DAPwell) is a planned geothermal well doublet, where relatively cold water is going to be injected through one well into a low enthalpy geothermal reservoir to produce hot water from the other well. The volume of the cold water around the injection well will increase over time and, in the end, result in a thermal...abstract 2022

Remmerswaal, G. (author), Hicks, M.A. (author), Vardon, P.J. (author)This paper investigates embankment reliability based on the ultimate limit state (ULS). The ULS is generally not clearly defined and, especially for flood defences, the ULS is currently under discussion. According to Dutch law [1], flooding which leads to either casualties or substantial financial damage is considered as the ultimate limit state...abstract 2018

Naranjo, D. (author), Parisi, Laura (author), Jónsson, Sigurjón (author), Jousset, Philippe (author), Werthmüller, D. (author), Weemstra, C. (author)The timing of the recordings of ocean-bottom seismometers (OBSs) is critical for accurate earthquake location and Earth model studies. GNSS signals, however, cannot reach OBSs deployed at the ocean bottom. This prevents their clocks from being synchronized with a known reference time. To overcome this, we developed OCloC, a Python package that...abstract 2023

Houkes, C.B. (author)This study focuses on three different, often used methods to determine rock strength: needle penetration, unconfined compression and shear box tests. The investigations were done on calcarenite that was taken directly from the construction site of the new A2 highway tunnel in Maastricht, the Netherlands. Besides determining the strength, it was...bachelor thesis 2013

Van Adrichem, W. (author)Sand sculptures are an inspiration source for an environmentally friendly building material, consisting only of sand, clay and water. The art of sand sculpting is generally dealt with low technical consideration. There is a need of comprehensive technical look on this topic in order to make standards for sand-sculpting. This study involves...bachelor thesis 2016

Boekhout, S.G. (author)This research has tried to find a relation between particle settling velocity and shape. This was done by taking the settling velocity log-contrast of a non-spherical particle and an equivalent spherical particle. This log-contrast should be the logarithmic function of a certain shape factor. Settling data of several shapes were taken from...bachelor thesis 2012

Jansen, J.D. (author)This text forms part of material taught during a course in advanced reservoir simulation at Delft University of Technology over the past 10 years. The contents have also been presented at various short courses for industrial and academic researchers interested in background knowledge needed to perform research in the area of closed-loop...book 2013

Brinkgreve, R.B.J. (author), Post, M. (author)Displacement-based finite element calculations are primarily used for serviceability limit state (SLS) analysis, but the finite element method also offers possibilities for ultimate limit state (ULS) design in geotechnical engineering. The combined use of SLS and ULS calculations with partial safety factors according to the different design...conference paper 2015

Spruit, R. (author), Van Tol, F. (author), Broere, W. (author)If a calamity with a retaining wall occurs, the impact on surrounding buildings and infrastructure is at least an order of magnitude more severe than without the calamity. In 2005 and 2006 major leaks in the retaining walls of underground stations in Amsterdam and Rotterdam occurred. After these cases had been thoroughly studied it was concluded...conference paper 2015

Van Dalen, J.H. (author), Bosch, J.W. (author), Broere, W. (author)Flow processes, taking place during the concreting of diaphragm wall panels (D-wall panels), are of great importance for the quality of the wall. During this phase, the bentonite, present in the excavated trench, should be completely replaced by concrete in a controlled way. In literature several cases are described in which this process...conference paper 2015

Harmankaya, U. (author), Kaslilar, A. (author), Thorbecke, J.W. (author), Wapenaar, C.P.A. (author), Draganov, D.S. (author)The investigation and detection of near-surface structures (such as cavities, caves, sinkholes, tunnels, mineshafts, buried objects, archeological ruins, water reservoir, etc.) is important to mitigate geo- and environmental hazards. In a former study, we suggested a method based on active-source seismic interferometry for locating the...conference paper 2013

Barros, E.G.D. (author), Jansen, J.D. (author), Van den Hof, P.M.J. (author)This paper proposes a new methodology to perform value of information (VOI) analysis within a closed-loop reservoir management (CLRM) framework. The workflow combines tools such as robust optimization and history matching in an environment of uncertainty characterization. The approach is illustrated with two simple examples: an analytical...conference paper 2014

De Gast, T. (author), Vardon, P.J. (author), Jommi, C. (author), Hicks, M.A. (author)Regular dyke assessment is part of reducing the risk of flooding in the Netherlands. 18 000 km of dykes are assessed at regular intervals, of which 14 000 km are classified as regional dykes and their main aim is to defend polders from inundating. The methods of assessing regional dykes are strongly inter-twined with the methods of assessing...conference paper 2015

Vardon, P.J. (author), Yao, Y. (author), Van Paassen, L.A. (author), Van Tol, A.F. (author)Thin-lift atmospheric fine drying (AFD) is a technique used to dewater mine and oil sand tailings, which utilises both self-weight consolidation and atmospheric evaporation. The disposed layers undergo a cyclic drying and rewetting process due to precipitation and deposition of additional lifts on top of the dried layer. The current research...conference paper 2015

Maffei, C. (author), Gambardella, C. (author), Menenti, M. (author)Forest fires are a threat for both the environment and the security of citizens. This is particularly relevant in the Mediterranean, where the population density is high, and long dry summers drive vegetation into fireprone conditions. Policy makers underline the key role of prevention over damage reparation, and indeed efforts are conducted at...conference paper 2015
