van der Linde, Lisa (author), Leclercq, Vincent (author), Wopereis, Ligaya (author)The United States of America have a safety standard for flood protection of 1/100 year. However the flood protections in the Washington D.C. do not comply with this requirement. During this study the levees in Washington D.C. area were analysed and it was found, that in order to comply with the 1/100 safety standard the levees in the...student report 2018

Lendering, K.T. (author), Schweckendiek, T. (author), Kok, M. (author)Polders in the Netherlands are protected from flooding by flood defence systems along main water bodies such as rivers, lakes or the sea. Inside polders, canal levees provide protection from smaller water bodies. Canal levees are mainly earthen levees along drainage canals that drain excess water from polders to the main water bodies. The...journal article 2018

Koelewijn, A.R. (author), Bridle, R. (author)Dams and dikes are both water-retaining earth embankments. These are vulnerable to internal erosion but specific differences lead to varying vulnerabilities to different types of internal erosion: • Dams are usually zoned, with potential filtering capability to arrest piping if it is initiated, while dikes are more commonly unzoned and incapable...conference paper 2017

Plomp-van der Sar, E. (author)The Houston Metropolitan area is a hurricane prone area and vulnerable to flooding by large storm surges caused by these extreme storm events. The area is a major economic center in the State of Texas and even the whole United States. Protection of the area against flooding is extremely necessary to protect the economy, community and environment...master thesis 2016

van Wesenbeeck, B (author), de Boer, W.B. (author), Narayan, Siddharth (author), van der Star, Wouter R L (author), de Vries, Mindert B. (author)Adaptation planning for flood risk forms a significant part of global climate change response. Engineering responses to higher water levels can be prohibitively costly. Several recent studies emphasize the potential role of ecosystems in flood protection as adaptive risk reduction measures while also contributing to carbon fixation. Here, we...journal article 2016

Oosterlo, P. (author)In this thesis, a method was developed, with which the infragravity waves and morphological changes of a sandy foreshore are included in the calculation of the probability of dike failure due to wave overtopping. Constructing a natural foreshore in front of the dike can be an attractive and innovative method to decrease the failure probability....master thesis 2015

Otake, Y. (author), Honjo, Y. (author), Hiramatsu, Y. (author), Lee, K. (author), Kodaka, T. (author)A design scheme is proposed to evaluate the safety of continuous linear structure i.e. river levee. The scheme is developed to establish a procedure to continuously evaluate the stability failure of embankment during flood runoff by seepage, and to identify locations for reinforcement of river levee. A 20km stretch of a fairly large river...conference paper 2015

Kanning, W. (author), Bocovich, C. (author), Schweckendiek, T. (author), Mooney, M.A. (author)Piping failure of levees is one of the main contributors to flood risk. Piping occurs when the head difference over a levee results in uplift of the inland blanket, followed by backward erosion in the aquifer due to high local flow velocities. Whether piping occurs, highly depends on local geo-hydrological circumstances which are uncertain due...conference paper 2015

Honjo, Y. (author), Moro, H. (author), Ishihara, M. (author), Otake, Y. (author)The ministry of land, infrastructures, transportation and tourism (MLIT) of the Japanese government maintains governmental managed river levee for the safety against flood whose total length is more than 10,000 km. The design standard of river levee had been traditionally done based on so called shape based specification, where levee is judged...conference paper 2015

Jonkman, S.N. (author), Schweckendiek, T. (author)This paper presents and overview of advances in flood risk and levee reliability analysis in the Netherlands. It is described how new safety standards – in the form of a target failure probability – have been derived on the basis of nationwide flood risk assessments which taken into account both economic risk and risk to life. The process for...conference paper 2015

Sanders, M.P.M. (author), Wiggers, A.G. (author)Traditionally Dutch design codes require a minimum distance between a pipeline and the toe of the levee: the ‘safety zone’. The codes provide additional design and maintenance requirements for pipeline sections located within this ‘safety zone’. For existing pipelines, designed before the establishment of the codes, the sections located in the...conference paper 2015

Boulware, L. (author), Rice, J. (author)It has long been understood that subsurface geology affects internal erosion potential in levee foundations. Geomorphic features associated with fluvial deposition environments are known to concentrate or block seepage, resulting in sand boils and internal erosion. However, incorporating the effects of geomorphic features into either...conference paper 2015

De Raadt, W.S. (author), Jaspers Focks, D.-J. (author), Van Hoven, A. (author), Regeling, E. (author)The most famous dam of the Netherlands, the Afsluitdijk, is in need of renovation. Hydraulic conditions for the year 2050, for some aspects even 2100, must be considered during the renovation of the dam originally constructed 1927-1933. A combination of sea level rise due to climate change and a change in the applied statistical methods result...conference paper 2015

De Visser, M.M. (author), Kanning, W. (author), Koopmans, R. (author), Niemeijer, J. (author)Research to the failure mechanism piping (internal, backward erosion) in the Netherlands shows that the dikes require costly berms to meet the required safety standards. According to the Sellmeijer piping-formula, the d70 (70%-quantile of the grain size distribution by weight) is an important parameter in the resistance against piping. Therefore...conference paper 2015

Broers, B.W.L. (author)After the flood of 1993 and 1995 in the Netherlands, flood risks in Limburg became an important discussion. Each flood defence system along the river Meuse needs to be provided with a safety level with an annual failure probability of 1/250. In the nearby future a new safety philosophy will be introduced, entailing new safety norms and...master thesis 2015
