Large parts of the Netherlands lay below mean sea level. An extensive network of flood protection measures is in place to prevent flooding. Periodic safety assessment and reinforcement are required to guarantee a resilient system. Currently, in the Netherlands, an extensive sea dike reinforcement program is underway to meet the safety standards...

The city of Utrecht is famously known for the system of canals and the wharf cellars integrated to the heart of the city, whose construction dates back to the 1300s. Due to increased traffic volume which caused the increase in dead load and traffic load, it is important to assess the safety and state of maintenance of these historical structures...

We study a diagnosis scheme to reliably detect the active mode of discrete-time, switched affine systems in the presence of measurement noise and asynchronous switching. The proposed scheme consists of two parts: (i) the construction of a bank of filters, and (ii) the introduction of a residual/threshold-based diagnosis rule. We develop an...

Under the current climate change projections, droughts and extreme rainfall events are becoming more common and intense. During sustained droughts, soil cracks can develop in the topsoil of a dike. These soil cracks can enhance the infiltration and drainage of the dike, affecting the dike stability. This study’s main objective is to better...

Coastal areas around the world have always been densely populated areas. However, sea-level-rise and an increase in single extreme events due to climate change, threaten the coastal areas and their inhabitants. Governmental organizations, coastal managers and various private parties thrive for better insights into long-term shoreline behavior...

With changing climatic conditions, droughts are expected to increase in duration and intensity. Under drying conditions, desiccation cracks can form in clay soil, which is often used as dyke cover and in some cases also for the core of the dyke. These desiccation cracks have a potential impact on the stability of dykes. The main objective of...

The question of how well in terms of safety can a driver take over control of an automated vehicle in response to an emergency situation is of crucial importance. Most of the studies performed so far focus on the drivers’ reaction times and the mechanisms behind the transition. In this study, an effort is made to incorporate the braking times...

The increasing demand for chemical products has driven the construction and development of chemical industrial areas, or so-called 'chemical industrial parks' (CIPs), but this has intrinsically raised the risk of major accidents. Therefore, it is significant and urgent to summarize the state of art and research needs in the field of CIP...

Wauben, Chris (author)
The Twin Dike project is an innovative concept to achieve the required flood safety while being able to preserve valuable areas. A lower, second dike is constructed behind the original existing dike. The original dike is only being strengthened to a minimal extent. The general idea behind this project is to more efficiently use the area near the...

'De Slufter' is a nature conservation area located in the Northwest of the Dutch Wadden island Texel which is inundated with seawater during storm events. The landward side of De Slufter is a sand dike which is part of the primary coastal defence ring of the island. HHNK, which is responsible for the coastal safety of Texel, currently relocates...

System safety and reliability assessment relies on historical data and experts opinion for estimating the required failure probabilities. When data comes from different sources, be it different databases or subject domain experts, the estimation of accurate probabilities would be very challenging, if not impossible, and subject to high epistemic...

Deployable morphing aircraft are gaining popularity in the academic and industrial world. Their deployability offer the possibility to be stored and takes less space. This is advantageous in volume limited applications like space explorations, where every cubic centimeter is important. Another field where this aircraft is increasingly used is...

Machine learning applications are increasingly being implemented in socio-technical safety-critical systems, but the safety of these applications is not well understood. This thesis used a mixed-method design and applied four methods to explore the field of machine learning and safety. With the results of these four methods, a framework was...

In order to perform a reassessment of existing structures or design new structures in a more efficient and economical way non-linear finite element (NLFE) models are used to take into account all non-linear behavior in reinforced concrete structures. The Model Code 2010 (fib, 2012) suggest several safety formats to perform non-linear finite...

This Thesis studies the safety assessment method for macro-stability of dikes with high foreshores. Currently, this method is a semi-probabilistic method, which does not take the presence of a foreshore into account. The research concludes that the presence of a foreshore has a significant influence on the failure probability with respect to...

Shallow foreshores in front of coastal dikes can reduce the probability of dike failure due to wave overtopping. A probabilistic model framework is presented, which is capable of including complex hydrodynamics like infragravity waves, and morphological changes of a sandy foreshore during severe storms in the calculations of the probability of...

The application of non-linear finite element analysis is important nowadays to simulate the real behavior of structure. A sort of non-linear finite element analysis with and without safety formats referring to Model Code 2010 is applied in this thesis, to study the FEM simulation of the shear capacity of reinforced concrete structure. A case...

With the implementation of new legal aspects for dune safety assessment in 2017, the current method, Duros+, is no longer feasible to represent the desired processes. This 1D deterministic, volume-balance model cannot simulate processes like inundation and overwash, which are crucial to fulfil the new requirements for dune safety assessment....

Inclusion of safety formats method in nonlinear finite element analysis of a structure is beneficial to realize<br/>the safe and real behavior of structures. In addition, reliability analysis in combination with NLFEA results<br/>and safety assessments provide an insight into consistency of the safety assessments recommendations related<br/>to...
