Rijcken, T. (author), Kok, M. (author)In the spring of 2008, Delft University of Technology wrote a report for the Second Delta Committee, a body set up to advise the Dutch government and parliament on the Netherlands’ long-term flood risk policy. The Delft report included a colourful drawing of a solution for Rotterdam and the Drecht Cities, and the Delta Committee used this image...abstract 2010

Veerhuis, Lex (author), Kolen, B. (author), Kok, M. (author), Riedstra, D. (author)Design-criteria for flood-defences have a legal character in the Netherlands. Formerly, these flood protection standards were based on design-waterlevels, where a flood defence was implicitly supposed not to fail below this waterlevel. Since knowledge regarding dike-failure improved, a new risk approach has been developed based on a social cost...abstract 2017

Kok, M. (author)Prof.dr.ir. Matthijs Kok is Professor of Flood Risk at the Faculty of Civil Engineering and Geosciences at TU Delft; he was Program leader of the ‘Integral and Sustainable Design of Multifunctional Flood Defenses’ research program, funded by the Dutch Science and Technology Foundation STW. Presently, he is...book chapter 2017

Kok, M. (author), Brand, A.D. (author)The saying goes that ‘Everything is bigger in Texas.’ This holds true for both the flood risk in the Houston-Galveston Bay Area, and for the complexity of issues that need to be dealt with in order to reduce it – assuming there is agreement that the current risk is unacceptable. There is currently no formal...book chapter 2017

Kok, M. (author)Many functions are combined in the Rotterdam Roof Park project: It is a shopping mall, a parking garage, a park on the roof, and last but not least, a flood defense. The research in our program was done after the buildings and structures had been built. So the research projects were not hampered by the...book chapter 2017

Brand, A.D. (author), Kok, M. (author)When the MFFD program took off in 2012, its general goal was to gain a deeper understanding of multifunctional flood defenses, in order to provide a solid foundation for their design, assessment and management. As a point of departure, it assumed that a new generation of explicitly multifunctional flood defenses...book chapter 2017

Kok, M. (author)Risk-informed decision-making needs methods for assessing flood risk, and often the flooding probability and the consequences of floods (such as economic damage and fatalities) play an important role in the risk assessment. Also, measures to reduce the flood risk need to be formulated, in order to make a risk-informed decision, whether to...book chapter 2022

Klerk, W.J. (author), Kok, M. (author), de Bruijn, K.M. (author), Jonkman, S.N. (author), van Overloop, P.J. (author)In the Netherlands, flood risk analysis is usually carried out for a location, without considering potential flood defence failures in upstream areas. This may result in significant over- or underestimation of flood risks. The effect of upstream failures on failure probabilities and flood risks in other areas is called load interdependence of...conference paper 2014

Lendering, K.T. (author), Jonkman, S.N. (author), Kok, M. (author)During flood events emergency measures are used to prevent breaches in flood defences. However, there is still limited insight in their reliability and effectiveness. The objective of this paper is to develop a method to determine the reliability and effectiveness of emergency measures for flood defences. The investigation is focused on measures...conference paper 2014

Schipper, H.R. (author), Grunewald, S. (author), Eigenraam, P. (author), Raghunath, P. (author), Kok, M. (author)Free-form buildings tend to be expensive. By optimizing the production process, economical and wellperforming concrete structures and elements can be manufactured. In this paper, an innovative method is presented that allows producing highly accurate double curved-elements without the need for milling two expensive mould surfaces per single...conference paper 2014

Spekkers, M.H. (author), Ten Veldhuis, J.A.E. (author), Kok, M. (author), Clemens, F.H.L.R. (author)Insurance databases form a promising data source that can be used to improve pluvial flood damage estimations. This paper describes the key characteristics of an insurance database on water related damages to private buildings and content in the Netherlands that has been made available for research. The paper presents preliminary results of a...conference paper 2011

Spekkers, M.H. (author), Kok, M. (author), Clemens, F.H.L.R. (author), Ten Veldhuis, J.A.E. (author)Intense rainfall may locally cause considerable damage in cities, e.g. because of sewer floods. A better understanding of relationships between rainfall characteristics and rainfall-related damage can help insurers and flood authorities to respond more adequately to rainfall extremes. This paper aims to study to what extent weather radars can be...conference paper 2013

Van der Krogt, M.G. (author), Van den Ham, G.A. (author), Kok, M. (author)Flow sliding of submerged slopes in front of dikes can affect the reliability of flood defences. The occurrence of flow sliding may result, sometimes with delay, in a failure mode and consequent flooding. The current safety assessment method for flow sliding does not consider the interaction between flow sliding and failure modes which can cause...conference paper 2015

Rijcken, T. (author), Kok, M. (author)It is possible to reduce flood risk in estuaries without having to drastically modify the river banks by levees or to block shipping routes and ecological flows by dams. ‘Storm surge barriers’ close off a river mouth at times of high sea water levels, but keep the river open during calmer times. ‘Moveable river flood barriers’ direct a river...conference paper 2011

Unprecedented low-probability events can happen even in the most well monitored areas, causing major social-economic disruption. Failing to prepare...conference paper 2013

Kok, M. (author), Schipper, H.R. (author), Grunewald, S. (author), Nijsse, R. (author)The construction of buildings with fi-ee-form surfaces can be accompanied with relatively high costs. An innovative method to produce free-form surfaces in concrete is the application of double-curved precast panels produced with a flexible re-usable mould technique. Traditional placing of reinforcing bars to strengthen such panels causes...conference paper 2014
