Schoolderman, J. (author), Reedijk, B. (author), Vrijling, J.K. (author), Molenaar, W.F. (author), Ten Oever, E. (author), Zijlema, M. (author)A new concept for wave energy conversion is examined as a proof of concept for generating electricity in a moderate wave climate while being integrated in a caisson breakwater. Physical model testing is performed to analyse the preliminary efficiency of the device and to identify areas of improvement. The resulting device is calculated for two...conference paper 2011

Zhu, Y. (author), Visser, P.J. (author), Vrijling, J.K. (author), Wang, G.Q. (author)Breaching of embankments has recently drawn more and more attention due to its importance in the development of early warning systems for embankment failures, in the evacuation plans of people at risk, in the design method of embankments based on a risk-approach, etc. The erosion process observed during embankment breaching tests in the...journal article 2011

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

Dawotola, A.W. (author), Van Gelder, P.H.A.J.M. (author), Vrijling, J.K. (author)A model is constructed for risk management of crude pipeline subject to rupture on the basis of a methodology that incorporates structured expert judgment and analytic hierarchy process (AHP). The risk model calculates frequency of failure and their probable consequences for different segments of crude pipeline, considering various failure...journal article 2011

Tsimopoulou, V. (author), Kanning, W. (author), Verhagen, H.J. (author), Vrijling, J.K. (author)This paper presents the development of a semi-probabilistic method for armour layer design of rubble mound breakwaters, which is based on the use of safety factors. The objective is to introduce an approach that is both attractive to designers and sufficiently reliable when a high degree of uncertainty is involved in the design process. The main...conference paper 2011

Jonkman, S.N. (author), Jongejan, R.B. (author), Maaskant, B. (author), Vrijling, J.K. (author)The Dutch government is in the process of revising its flood safety policy. The current safety standards for flood defences in the Netherlands are largely based on the outcomes of cost-benefit analyses. Loss of life has not been considered separately in the choice for current standards. This article presents the results of a research project...conference paper 2011

Jongejan, R.B. (author), Ranasinghe, R.W.M.R.J.B. (author), Vrijling, J.K. (author)Economic and population growth have led to an unprecedented increase in the value at risk in coastal zones over the last century. To avoid excessive future losses, particularly in the light of projected climate change impacts, coastal zone managers have various instruments at their disposal. These primarily concern land-use planning ...conference paper 2011

Vrijling, J.K. (author), Schweckendiek, T. (author), Kanning, W. (author)Current design codes like the Eurocode use safety or reliability classes to assign target reliabilities to different types of structures or structural members according to the potential consequences of failure. That, in essence, is a risk-based criterion. A wide range of structures is designed with such codes, and distinction is made between...conference paper 2011

(author)The application of reliability analysis in civil engineering is still an emerging technology, more so in geotechnical engineering and even more so in application to river dikes. However, much experience remains to be gained, recently, especially in European countries (the Netherlands, Germany, United KingdomÂ…) as well as in the United States of...conference paper 2010

Nguyen, D.V. (author), Van Gelder, P.H.A.J.M. (author), Verhagen, H.J. (author), Vrijling, J.K. (author)In order to avoid failure in its lifetime, a breakwater system has to be inspected and, if necessary, has to be repaired. In this paper, a comprehensive maintenance strategy with optimal inspection planning is formulated. Rational maintenance decision-making approaches are discussed. The proposed maintenance strategy combines time-dependent and...conference paper 2010

(author)This paper aims at risk analysis and the investigation of safety aspects of coastal flood defences in Vietnam. The sea dike system has been actually designed by a 20 to 25 years return period. From the current situation it seems that the dike system is not sufficient to withstand the actual sea boundary conditions. Accurate safety assessment of...conference paper 2008

Viet, N.D. (author), Verhagen, H.J. (author), Van Gelder, P.H.A.J.M. (author), Vrijling, J.K. (author)In 2006 a Vietnamese Engineering Consultancy Company carried out a design study of a Naval Base at the location of the South of Doson Peninsula in Vietnam. A deterministic approach applied to the conceptual design of the breakwater system of the Naval Base resulted in a cross-section with a big armour layer and a rather low crest level. This...conference paper 2008
