De Vries, S. (author), De Schipper, M.A. (author), Ranasinghe, R.W.M.R.J.B. (author), Stive, M.J.F. (author)The coastal system consists of a sub-aqueous and a sub-aerial zone which can be separated by a border. At this border sediment exchange takes place from one zone to the other. This paper hypothesizes that conditions and therefore sediment exchange at this border are dependent on active profile characteristics. To analyze morphological...conference paper 2011

Groot, J. (author), Richstein, J.C. (author), De Vries, L.J. (author)In order to understand how companies make investment decisions under conditions of deep uncertainty, we interviewed a number of actors in the Dutch electricity sector. Most of the economic literature that is devoted to this question is prescriptive in nature, describing rational methods to the investment decision process (such as real options...conference paper 2013

Mooyaart, L.F. (author), Jonkman, S.N. (author), De Vries, P.A.L. (author), Van der Toorn, A. (author), Van Ledden, M. (author)In this study an overview of existing and planned storm surge barriers in the world is provided. 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

Van Geer, P. (author), De Vries, S. (author), Van Dongeren, A. (author), Van Thiel de Vries, J.S.M. (author)This paper describes the validation of the dune erosion model XBeach with laboratory measurement data of dune erosion in the presence of sea walls and revetments. Simulation results show that the essential dune set back processes are captured by the model and that the measurements at most locations are approximated quite well. Some aspects...conference paper 2012

As a result of the intensification of extreme weather conditions and human activities in this area (e.g. land reclamation, river damming, and coastal structures), coastal safety as well as economic and ecological values...conference paper 2015

Hoonhout, B.M. (author), De Vries, S. (author), Baart, F. (author), Van Thiel De Vries, J.S.M. (author), Van der Weerd, L. (author), Wijnberg, K. (author)Existing aeolian transport formulae tend to overestimate the sediment transport volumes in coastal environments. Supply limiting factors like moisture content, shell patches, sediment sorting, vegetation and morphological features are believed to explain these overestimations. These supply limitations act on a variety of spatio-temporal scales...conference paper 2013

(author)Typically a beach is out of equilibrium after a nourishment is installed. To observe how a nourished beach behaves on the timescale of storms a monitoring campaign was set up at Vlugtenburg beach after a nourishment in the spring of 2009. Here we show a sediment budget analysis of the first 2.5 years for a coastal domain spanning 1750 m...conference paper 2012

De Vries, S. (author), Van Thiel de Vries, J.S.M. (author), Ruessink, G. (author)This paper aims to conceptually simulate observed spatial and temporal variability in aeolian sediment transport rates, erosion and deposition on a beach. Traditional strategies of modeling aeolian sediment transport rates do not account for supply limitations that are common on natural beaches. A recently developed 1D linear advection model is...conference paper 2013

(author), Cohen, A. (author)Morphodynamic changes at sandy coasts, as are dominant in The Netherlands, are typically monitored at yearly intervals by means of LIDAR. Meanwhile it is recognized that beach morphodynamics is not a regular process but is strongly correlated to meteorological conditions. A time series of 14 terrestrial laser scans of a beach experiment is...conference paper 2010

One of the criteria for candidate states for EU membership is an effective monitoring system for the land and real estate markets. The objective of this paper is twofold. First, the development of a set of databases, procedures and...conference paper 2009

Broekens, D.J. (author), Kosters, W.A. (author), De Vries, T.

We show that the card game SET is a good candidate for investigating the relation between top-down versus bottom-up visual information processing. Further, we show that...conference paper 2009

(author)In this paper a new wave pool concept is presented using ship hulls as wave generators. To evaluate the potential of such a concept a towing tank experiment is conducted to investigate ship wave generation in a confined space. In the towing tank experiment various hull sizes and velocities are examined to maximize the generated wave height. The...conference paper 2009

This means that the vehicles in the swarm autonomously take care of flying in formation, resulting in steering the swarm, instead of all the individual vehicles being tasked separately.
