Meijer, Friso (author)From the 3500 kilometers of primary flood defenses in the Netherlands, a third does not comply with the current standards. As a result, over 700 kilometers will be strengthened in the upcoming years. Traditional strengthening of dikes consists of strengthening with soil and requires space that is often not available. Further strengthening of...master thesis 2019

Leunge, Laurens (author)In the Netherlands, robust dike and dam design is a major concern in the context of flood defence. Due to heterogeneity of the subsoil on which these structures are founded, the validity range of in situ tests decreases drastically. Consequently, large uncertainties regarding spatial variation of soil stratification and soil layer parameters are...master thesis 2019

Driebergen, Joost (author)Almost four million people in the Netherlands who live below sea level are protected by 17000 km of dikes against the water. Since deformation can be an indicator of a developing failure mechanism, information about this parameter can help authorities to detect weak spots in the dutch water defense structures. <br/>In this research, Radar...master thesis 2019

Pol, J.C. (author), van Beek, Vera (author), Kanning, W. (author), Jonkman, Sebastiaan N. (author)Backward erosion piping is an important failure mode of dikes and dams. The time required for the backward erosion process to result in dike failure is expected to be an important factor in the safety of dikes. This holds especially in coastal and estuarine areas which are dominated by storm surge, and pipes may not fully develop during a storm....conference paper 2019

Klerk, W.J. (author), Kanning, W. (author), van Veen, Nelle-Jan (author)Many flood defences in the Netherlands will have to be reinforced in the coming decades. Many dikes do not fulfill the safety standard due to geotechnical failure modes, largely due to epistemic, reducible uncertainties. . The Value of Information is a measure to indicate beforehand whether an investment towards reducing epistemic uncertainty is...conference paper 2019

Oosterlo, P. (author), Hofland, Bas (author), van der Meer, J.W. (author), Overduin, Maarten (author), Steendam, Gosse Jan (author), Nieuwenhuis, Jan-Willem (author), van Vledder, G.P. (author), Steetzel, Henk (author), Reneerkens, Michiel (author)Wave overtopping is commonly measured using overtopping tanks. In this paper, an alternative system is developed by using two laser scanners. It measures wave run-up, as well as layer thicknesses and front velocities, both during normally and obliquely incident waves on a dike in the field. The paper considers the first field validation tests...conference paper 2019

Streicher, Maximilian (author), Kortenhaus, Andreas (author), Marinov, Krasimir (author), Hirt, Matthias (author), Hughes, Steven (author), Hofland, Bas (author), Scheres, Babette (author), Schüttrumpf, Holger (author)Short duration bores in the coastal zone are generated by wave breaking in shallow water and mild foreshore conditions. In storm weather situations and for sea level rise scenarios, these bores approach the dike and interact with previously overtopped or reflected bores. Combined laser scanner and video measurements were used to study the...journal article 2019

Curran, A.N. (author), de Bruijn, Karin M. (author), Klerk, W.J. (author), Kok, M. (author)To make informed flood risk management (FRM) decisions in large protected river systems, flood risk and hazard analyses should include the potential for dike breaching. 'Load interdependency' analyses attempt to include the system-wide effects of dike breaching while accounting for the uncertainty of both river loads and dike fragility. The...journal article 2019

Gebert, J. (author), Groengroeft, Alexander (author)Purpose: Climate change necessitates heightening and strengthening of dikes, requiring large volumes of suitable soil. This study investigated soil ripening and long-term development of hydraulic behaviour of a dike constructed from slightly contaminated, partially dewatered dredged material from the Port of Hamburg under realistic conditions...journal article 2019

Lengkeek, H.J. (author), Post, M. (author), Breedeveld, J. (author), Naves, Thomas (author)Dikes in the Netherlands have traditionally been constructed with soil. Climate change and subsidence requires heightening and or reinforcing these existing dikes. Traditional reinforcements demand additional space, which in some cases conflicts with existing buildings. Applying sheet pile walls in dikes allows for strengthening while minimizing...conference paper 2019

Verhagen, H.J. (author)In this paper, protection options for a high-value, industrial area along the coast of West Bengal (India) are investigated. The options are designed to protect against cyclone surges with a probability of 1/100 per year. Two alternatives are compared, a classical solution of a dike with a revetment and a solution with a mangrove belt in...journal article 2019

Klerk, W.J. (author), Schweckendiek, T. (author), den Heijer, Frank (author), Kok, M. (author)One of the most rapidly emerging measures in infrastructure asset management is Structural Health Monitoring (SHM), which aims at reducing uncertainty in structural performance by using monitoring equipment. As earthen flood defence structures typically have large strength uncertainties, such techniques can be particularly promising. However,...journal article 2019

van den Berg, Nick (author)In the Netherlands, a new assessment method for the required safety level of primary flood defences is introduced in the Water Act. It is estimated that currently roughly 1900 kilometres of flood protection does not meet the safety requirements for the future (Jonkman, Jorissen, Schweckendieck & Van den Bos, 2017). Past flood defence...master thesis 2018

Holtland, Julia (author)Since the industrial revolution we have become estranged from the sea. We became opponents instead of working together, and put up high walls to protect ourselves form the vagaries of an unpredictable sea. Somewhere along our path of progress, we lost our human connection to the sea. Before the sea became something we secluded, it was known for...master thesis 2018

Torres Alves, Gina (author)Before the Spanish conquest of Mexico, around the year 1519, the Valley of Mexico was a closed basin. As a result, at the bottom of the valley, an extensive system of shallow lakes, lagoons, and swamps was formed due to precipitation and permanent river’s discharge from the Sierra Nevada mountains. This lacustrine system occupied around 1000km2...master thesis 2018

Wubben, Dennis (author)Changes in the Earth’s climate system do have consequences for the river discharges. The development of the future climate is uncertain, which causes uncertainty in the future extreme river discharges. For flood protection considerations, it is important to quantify the climate uncertainties and its effects on extreme river discharges. In this...master thesis 2018

Wever, Esther (author)One of the main challenges in dike design in the Netherlands is to guarantee a sufficient safety level against the development of macro-instabilities in a dike. A case study was performed on a dike section at Herrewijnen-Opijnen, which is part of the Heesseltse Uiterwaarden in the Dutch province of Gelderland. The dike located at this site no...master thesis 2018
