Shojaikaveh, N. (author), Rudolph, E.S.J. (author), Rossen, W.R. (author), Wolf, K.H.A.A. (author)CO2 storage in deep saline aquifers and depleted gas reservoirs is largely controlled by interfacial phenomena among fluid phases and rock pore spaces. Reduction of the interfacial tension may result in the mobilization of connate water (capillary trapping). In addition, dissolving CO2 in formation water is one of the most important mechanisms...conference paper 2014

Shojaikaveh, N. (author), Amerighasrodashti, A. (author), Rossen, W.R. (author), Bruining, J. (author), Wolf, K.H.A.A. (author)Carbon dioxide injection, either miscible or immiscible, has been known as an efficient strategy to enhance oil recovery as well as reduce CO2 emission. Wettability has a significant effect on the performance of enhanced oil recovery techniques because of its effect on fluid saturation distribution and flow behavior in porous media. For oil-wet...conference paper 2014

Zijlema, M. (author)This paper presents the application of the open source non-hydrostatic wave-flow model SWASH to propagation of irregular waves in a barred surf zone, and the model results are discussed by comparing against an extensive laboratory data set. This study focus not only on wave transformation in the surf zone, but also on the numerical prediction of...conference paper 2014

Donchyts, G. (author), Baart, F. (author), Van Dam, A. (author), Jagers, B. (author)The use of natural user interfaces instead of conventional ones has become a reality with the emergence of 3D motion sensing technologies. However, some problems are still unsolved (for example, no haptic or tactile feedback); so this technology requires careful evaluation before the users can benefit from it. We argue, that the best benefits...conference paper 2014

(author)A hampering factor in the application of morphodynamic models is the potential excessive time needed to complete a simulation. One way to upscale a model run is the use of a morphological factor, or MORFAC. In this paper, we investigate the upper limit to the value of the MORFAC as a function of model geometry and timestep for a schematized case...conference paper 2014

Hai, T.L. (author), Verhagen, H.J. (author)Many dike failures have been ignited by damage due to erosion on the landward slopes. This paper investigates how grass covered slopes perform when being attacked by overtopping flow during storm surges. Based on observations during a number of simulator tests, damage is classified into three types 'head-cut', 'roll-up' and 'collapse' depending...conference paper 2014

Knops, H.P.A. (author), De Vries, L.J. (author), Huygen, A. (author)In many countries, the characteristics of the electricity supply system are changing. Important developments that are unfolding in the electricity sector are (i) the growth of generation from renewable sources (PV, wind) that are less controllable than traditional power plants and that for a large part feed in into the distribution grids, and ...conference paper 2014

Richstein, J.C. (author), Chappin, E.J.L. (author), De Vries, L.J. (author)In recent years the Europe Unions emission trading system (EU ETS) has experienced very low prices. This has triggered a political discussion about stabilising the EU ETS and improving incentives for investing in CO2 abatement. As a result of this discussion, the EU parliament accepted a proposal of the EU commission on the backloading of EU...conference paper 2014

Numerical models are expected to be a useful additional research tool in this field, provided that their calculation results can be validated against measurements. This paper presents the results of a systematic effort...conference paper 2014

(author)The Sand Motor is a pilot project of a ‘mega-nourishment’ built in the Dutch coast in 2011. In order to understand which conditions reshape those mega-nourishments the influence of different types of forcing on the longshore sediment transport along the Sand Motor has been assessed in this paper using a process-based model. The use of numerical...conference paper 2014

A systematic analysis relates functional requirements (e.g. navigation and tidal exchange) to the main barrier characteristics (e.g. gate type, dimensions). Furthermore, as the costs of barriers are an important issue in the planning, available cost...conference paper 2014

(author)The Houston - Galveston area is at significant risk from hurricane induced storm surges. This paper summarizes ongoing studies on flood risk reduction for the region. Firstly, based on a simplified probabilistic hurricane surge model , the return periods of surges within the bay have been estimated. This model framework can be used to assess the...conference paper 2014
