(author)There is a growing international recognition that flood risk management in optima forma should be a programmed and flexible process of continuously improving management practices by active learning about the outcome of earlier and ongoing interventions and drivers of change. In the Netherlands, such a long-term, adaptive flood risk management...journal article 2012

Roth, M. (author), Buishand, T.A. (author), Jongbloed, G. (author), Klein Tank, A.M.G. (author), Van Zanten, J.H. (author)Regional frequency analysis is often used to reduce the uncertainty in the estimation of distribution parameters and quantiles. In this paper a regional peaks-over-threshold model is introduced that can be used to analyze precipitation extremes in a changing climate. We use a temporally varying threshold, which is determined by quantile...journal article 2012

Mostert, E. (author)One of the central tenets of adaptive management is polycentric governance. Yet, despite the popularity of the concept, few detailed case studies of polycentric governance systems exist. In this paper, we aim to partly fill this gap. We describe water management between the years 1000 and 1953 on the Dutch island of IJsselmonde in the...journal article 2012

Jonkman, S.N. (author), Dawson, R.J. (author)Recent flood-related disasters (Japan, Thailand, US, Australia) emphasize the need for an effective management of flood risks. As an introduction to this special issue, this editorial summarizes some of the key challenges in the field. Flood risk management needs to recognize the interconnections between infrastructures, economic systems and the...journal article 2012

Balica, S.F. (author), Wright, N.G. (author), Van der Meulen, F. (author)Worldwide, there is a need to enhance our understanding of vulnerability and to develop methodologies and tools to assess vulnerability. One of the most important goals of assessing coastal flood vulnerability, in particular, is to create a readily understandable link between the theoretical concepts of flood vulnerability and the day-to-day...journal article 2012

Mostert, E. (author)Lecture notes in DUTCH for course CIE5500, providing a detailed overview of Dutch and European water law concerning surface and groundwater, the North Sea and the Wadden Sea, water services, flood protection, spatial planning, nature protection, water management organizations (e.g. the water boards), financing and legal protection....journal article 2012

Raadgever, G.T. (author), Mostert, E. (author), Van de Giesen, N.C. (author)In order to deal with complex water management problems, it is increasingly claimed that researchers should collaborate with authorities and other stakeholders. According to the literature, such collaboration can enhance cognitive learning about the issues at stake, but there is little empirical evidence for this. In this paper, we assess...journal article 2012

Zhong, H. (author), Van Overloop, P.J. (author), Van Gelder, P. (author), Rijcken, T. (author)The Rhine River Delta is crucial to the Dutch economy. The Maeslant barrier was built in 1997 to protect the Rhine estuary, with the city and port of Rotterdam, from storm surges. This research takes a simple approach to quantify the influence of the Maeslant storm surge barrier on design water levels behind the barrier. The dikes in the area...journal article 2012

Rijcken, T. (author), Stijnen, J. (author), Slootjes, N. (author)The Dutch Delta Program is currently developing new government policies for flood protection and fresh water supply. Decision support instruments have to address the program’s technical and political complexity. The water system functions are highly interwoven and would benefit from an integrated approach on a national level, with decisions...journal article 2012

(author)This article assesses the risk to life for the Natomas Basin, a low-lying, rapidly urbanizing region in the Sacramento-San Joaquin Delta in California. Using an empirical method, the loss of life is determined for a flood (high water), seismic, and sunny-day levee breach scenario. The analysis indicated that more than 1000 fatalities may occur...journal article 2012

Jonkman, S.N. (author), Jongejan, R.B. (author), Maaskant, B. (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...journal article 2011

Ten Veldhuis, J.A.E. (author)This study presents a first attempt to quantify tangible and intangible flood damage according to two different damage metrics: monetary values and number of people affected by flooding. Tangible damage includes material damage to buildings and infrastructure; intangible damage includes damages that are difficult to quantify exactly, such as...journal article 2011

Stive, M.J.F. (author), Fresco, L.O. (author), Kabat, P. (author), Parmet, B.W.A.H. (author), Veerman, C.P. (author)Over two-thirds of the Netherlands’ economy and half its population is below sea level. The Dutch government recently set out far-reaching recommendations on how to keep the country flood-proof over the next century given the likelihood of rising sea levels and river flows. This paper explains the recommendations, which are based on a gradual...journal article 2011

Van der Pijl, S.P. (author), Oosterlee, C.W. (author)This work aims to model the optimal control of dike heights. The control problem leads to so-called Hamilton-Jacobi-Bellman (HJB) variational inequalities, where the dike-increase and reinforcement times act as input quantities to the control problem. The HJB equations are solved numerically with an Essentially Non-Oscillatory (ENO) method. The...journal article 2011

Kleptsova, O. (author), Stelling, G.S. (author), Pietrzak, J.D. (author)In this paper, we focus on a conservative momentum advection discretisation in the presence of zlayers. While in the 2Dcase conservation ofmomentum is achieved automatically for an Eulerian advection scheme, special attention is required in the multi-layer case. We show here that an artificial vertical structure of the flow can be introduced...journal article 2010

Villada Arroyave, J.A. (author), Crosato, A. (author)The current river management policy in the Netherlands is to give rivers more space, mainly by main channel widening and floodplain lowering. The aim is to reduce flood water levels and to create more favourable conditions for river ecology. However, the effect on water levels gradually disappears due to sedimentation and vegetation growth on...journal article 2010

Van Baars, S. (author), Van Kempen, I.M. (author)In a historical perspective, flood protection in the past was not given high priority - plague and periods of famine and war took precedence. Poverty and a lack of knowledge made it difficult to create safer dikes. Dike engineering did improve in Napoleonic era due to the French Central Government, but many dikes still failed. A historical...journal article 2009

Ngigi, S.N. (author), Savenije, H.H.G. (author), Gichuki, F.N. (author)The upper Ewaso Ng’iro basin, which starts from the central highlands of Kenya and stretches northwards transcending different climatic zones, has experienced decreasing river flows for the last two decades. The Naro Moru sub-basin is used to demonstrate the looming water crisis in this water scarce river basin. The objective of the study was to...journal article 2008

Muller, M. (author)If the sea were to flood the southern parts of the agglomeration that covers most of the western part of the Netherlands, the death toll would be in the thousands, as predicted by a calculation method developed at Delft University of Technology (TU Delft). Evacuation would save precious few lives. So how can a disaster of this magnitude be averted?journal article 2006
