Petter, Lilly (author)The constant manipulation of the Dutch delta system and the resulting creation of hard borders between the natural river landscape, the harbor and the city has led to a destabilized delta system(Hein, 2021; Meyer et al., 2015). The spatial and ecological challenges resulting from population growth and the resulting urban growth, as well as...master thesis 2023

Pol, J.C. (author)Structural flood protection systems such as levees are an important component in flood risk reduction strategies. Levees can fail through various failure mechanisms; this thesis focuses on the mechanism Backward Erosion Piping (BEP) which occurs when a sandy levee foundation is eroded by groundwater flow. To assess whether a levee's reliability...doctoral thesis 2022

Klerk, W.J. (author)Many countries rely on flood defence systems to prevent economic damage and loss-of-life due to catastrophic floods. Asset managers of flood defence systems need to cope with the consequences of structural degradation, and changing societal and environmental conditions, in order to satisfy performance requirements and optimize societal value of...doctoral thesis 2022

Jilesen, Vince (author)Flooding is one of the most damaging natural disasters worldwide, and presents a signi_cant risk for a large amount of the global population. For the development of ood disaster management strategies, policy makers make use of ood hazard maps to inform investment strategies to reduce risk. In many current ood hazard mapping methods, the role of...master thesis 2022

Without our dikes and dunes, 60% of the Netherlands would flood on a regular basis. This area is home to 9 million people. The latest<br/>report of the Intergovernmental Panel on Climate Change (IPCC, February 2022) underlines the importance of reinforcing water safety. Sea levels are rising and extreme weather is becoming increasingly common....book 2022

Lashley, Christopher H. (author)Coastal communities across the globe are often protected by structures, such as seawalls, levees or dikes, which allow only a safe volume of water to pass over or “overtop” them due to wave action during storms. The area seaward of these structures is often characterised by shallow, gently sloping beds referred to as foreshores.<br/>As storm...doctoral thesis 2021

Vrinds, Thijs (author)Climate change is increasingly becoming more impactful on our society. Recent events such as the extreme rainfall in the summer of 2021 in Germany, Belgium and The Netherlands and hurricane Ida in Mississippi (USA), caused severe floodings and damages in these areas. Climate change, in turn, leads to an increase in sea level rise, making flood...master thesis 2021

van Grondelle, Bart (author)This master thesis is about the positive effects of river system behaviour along the river IJssel. Due to failure of the flood defences along the IJssel, the protected areas will flood and water will flow out of the river. The discharge in the river will decrease and thus the water level at the downstream ends of the river will also decrease....master thesis 2021

Buitelaar, Maarten (author), Rademaker, Rolf (author), Lengkeek, Robert (author), Wever, Jason (author)In this assignment we simulate a two meters wide dike stretch which is subjected to overflow. Three failure mechanisms could occur due to overflow: full erosion of the soil of the dike, macro instability of the levee if too much soil is eroded away, leading to insufficient counterweight on the inside of the levee, and surface slip failure due to...student report 2021

Wopereis, Ligaya (author)River floods are becoming increasingly devastating because of climate change (more frequent and extreme rainfall), population growth and the increasing economic importance of river basins. This situation requires maintenance and strengthening of flood-defence systems.<br/><br/>Adding certain types of vegetation at precise locations for their...master thesis 2021

Klerk, W.J. (author), Kanning, W. (author), Kok, M. (author), Bronsveld, J. (author), Wolfert, A.R.M. (author)Prioritisation of flood defence maintenance is typically based on visual inspection. However, literature shows that the Probability of Detection (PoD) of visual inspection can vary significantly. Here we investigate the PoD for visual inspections of flood defence structures, the consistency of damage classification, and the influence of...journal article 2021

Klerk, W.J. (author), Kanning, W. (author), Kok, M. (author), Wolfert, A.R.M. (author)Climate change and deterioration require a continuous effort to reinforce flood defences and meet reliability requirements. To efficiently upgrade flood defence systems, insight in costs and benefits of measures at a system level is required throughout the process of planning and design. Due to the size of flood defence systems the number of...journal article 2021

Marijnissen, Richard J.C. (author), Kok, M. (author), Kroeze, Carolien (author), van Loon-Steensma, J.M. (author)In this paper the safety of a double-dike system (or twin dikes) is assessed. Such a system consist of two parallel lines of flood defences. During storms the combined strength of the parallel flood defences must prevent flooding of the hinterland. A culvert can be implemented for the tidal exchange of sea water to enable new land-uses in the...journal article 2021

Rijnink, Alexandra (author)A dam including a tidal power station with pumping capacity is a new type of flood defence. The negative ecological impact normally associated with closure dams is partially mitigated by including a tidal power station in the structure. Water can move through the tidal power station resulting in a reduced tidal stroke at the created lake. This...master thesis 2020

Babu Gheethaa, Mukkund (author)A high-resolution hydrological solver that solves on time-adaptive grids is created. The solver uses h-refinement strategies which adapts the resolution of the grid using a posteriori measure. It is based on an open-source scientific computing library named PETSc. With the use of highly scalable time-stepping solvers provided by PETSc, an...master thesis 2020

Kool, J.J. (author), Kanning, W. (author), Jommi, C. (author), Jonkman, Sebastiaan N. (author)Hindcasting of past levee failures enhances insights in the performance and vulnerability of levees. The scarcity of field evidence makes identifying the cause(s) of failure difficult. Under these circumstances, multiple scenarios and model choices are possible to characterise and to model the failure. This paper shows how probabilistic...journal article 2020

Dupuits, E.J.C. (author)Historically, people in flood-prone areas world-wide have (to a certain degree) accepted the risk of being flooded because of the benefits that flood-prone areas can provide; examples of such benefits are rich agricultural lands or trade advantages. Acceptance and benefits notwithstanding, people living in flood-prone areas have tried, and will...doctoral thesis 2019

Niazi, Muhammad Hassan Khan (author)The increasing frequency and intensity of extreme events due to global warming and climate change is increasing flood risk. To act, rather than react, nature-based solutions (NBS) involving vegetation and wetlands are being explored on top of conventional solutions like dikes. WHY? There was a dire need for global study quantifying the potential...master thesis 2019

Overbosch, Niels (author)Reinforcing levees with traditional methods is becoming more difficult in the Netherlands. Often there is a lack of space near the levee or it is desired that the landscape is maintained. Because of this, alternative methods for reinforcing levees are still sought after (CUR-commissie C141, 2007). In this study, the technical feasibility of a...master thesis 2019

Çete, Ceylan (author)It is already acknowledged that Nature-based Solutions can be used to attenuate waves, however it is still uncertain to what extent the vegetation can contribute to decreasing the flood risk. So far mainly small-scale tests have been performed to quantify wave attenuating properties of vegetation. To quantify the effect of more extreme wave...master thesis 2019
