Bisdom, K. (author), Bertotti, G. (author), Bezerra, F. H. (author)Regional natural fracture networks often show variations on a scale below that captured by seismic reflection data. This variability is not considered in most reservoir models, but likely impacts uncertainties in permeability. We quantify this uncertainty using a database of 13,000 fractures in nine outcrops digitised in the carbonate...journal article 2017

Stovers, M.J.P. (author)Gravity currents are common around the world, consider for instance avalanches and pyroclastic flows. The kind of gravity currents that this research focuses on occur below the water surface. During dredging operations soil is cut and transported, during many of these processes sediment is introduced into the environment. Consider for instance...master thesis 2016

Sri Paravastu, R.K. (author)Offshore pipeline installation is limited by pipeline integrity during the laying process. Pipeline integrity is evaluated with the help of buckling checks, which help determining the feasibility of pipeline installation for a given sea condition. The operational limit of pipeline installation is determined during project preparation, by...master thesis 2016

Helsloot, T.C. (author)Due to increasing marine traffic intensity on inland waterways the interaction between ships and banks is becoming more of a problem. Bank effects make ship manoeuvring more difficult and rivers need to be protected against ship-induced currents and waves. This thesis contributes to the development of a new method that simulates these ship-bank...master thesis 2016

Ishiyama, T. (author), Blacquière, G. (author)For 3-D shallow-water seismic surveys offshore Abu Dhabi, imaging the target reflectors requires high resolution. Characterization and monitoring of hydrocarbon reservoirs by seismic amplitude-versus-offset techniques demands high pre-stack amplitude fidelity. In this region, however, it still was not clear how the survey parameters should be...journal article 2016

Guo, L. (author)The main goal of this project is to predict the in uence of non-uniform basin depths on the stability of single inlet systems. This is achieved by making use of Escoffier's principle, which poses a relationship between the relative water flow velocity in an inlet and the rate of change of its cross-sectional area. To this end, a thorough...bachelor thesis 2016

Wei, X. (author), Schuttelaars, H.M. (author), Schramkowski, G.P. (author)Understanding salt dynamics is important to adequately model salt intrusion, baroclinic forcing, and sediment transport. In this paper, the importance of the residual salt transport due to tidal advection in well-mixed tidal estuaries is studied. The water motion is resolved in a consistent way with a width-averaged analytical model, coupled to...journal article 2016

Liu, J. (author), Hekkenberg, R.G. (author)An accurate estimation of the rudder forces and moments is essential for manoeuvrability prediction. Previous research has shown that ships have different manoeuvring performance in deep and shallow water. Before considering the rudder’s contribution to shallow water manoeuvring, it is meaningful to analyse the shallow water effects on the...conference paper 2016

Rotteveel, E. (author), van der Ploeg, A (author), Hekkenberg, R.G. (author)Shallow water effects change the flow around a ship significantly which can affect the optimum design of the hull. This paper describes a study into the optimization of the aft ship region for various water depths. The research focuses on variations of the following parameters of a hull form: The athwart ship’s propeller location, the tunnel top...conference paper 2016

Rotteveel, E. (author), Hekkenberg, R.G. (author)Effects of a hull form variation and shallow water on a 110-meter inland ship are presented as preliminary results of the Top Ships project, which is initiated in order to improve inland ship design tools and design guidelines.conference paper 2015

Rotteveel, E. (author), Hekkenberg, R.G. (author), Liu, J. (author)For inland ships, state-of-the-art hull form design is to a large extent based on experience, common sense, or adjusting previous designs. The idea therefore arises that further optimization is possible if the right knowledge is available. This knowledge is insufficiently available due to two main reasons. First, research into inland ship...conference paper 2014

Ambrozic, M. (author)Forecast models often depend on unknown parameters, such as model initial and boundary conditions, or other tunable parameters not necessarily having any physical meaning. Calibration of these parameters to minimize errors between forecasted and observed states is called data assimilation. A common approach in this context are variational...master thesis 2013

Rotteveel, E. (author)Manoeuvring simulations can be of good use in determining whether an inland ship may be allowed access to a certain channel/river or not. The SURSIM mathematical model is able to predict the necessary manoeuvres and can therefore be used to determine the acceptance of ships on fairways. However, the SURSIM program is mostly developed for use...master thesis 2013

Volp, N.D. (author), Van Prooijen, B.C. (author), Stelling, G.S. (author)This study presents a finite volume hydrodynamic model for shallow water flow that computes on a coarse grid, but accounts for high-resolution bathymetry and roughness variations on a subgrid. The detailed information can be incorporated by using the assumption of a uniform flow direction and a uniform friction slope within a part of a coarse...journal article 2013

Bart, L. (author)Wind waves are capable of dealing damage to hydraulic structures. In the ultimate case, the loads never exceed the strength of the structure. Unfortunately it is often impossible (or uneconomical) to design a structure that will fit this requirement. That is why structures are designed with a certain allowable probability of failure, displayed...bachelor thesis 2013

Diaferia, G. (author)On land, surface waves are extensively and successfully used for the determination of Shear velocity profile (MASW). From those, the stiffness of the subsurface within 20-30 m can be derived, useful especially for engineering purposes. This technique can be effectively applied also to shallow marine environments: surface waves ex- cited by air...master thesis 2012
