Nowadays, the ecological effects of dredge plumes are usually managed based on the precautionary principle. Predictions of suspended sediment levels are made, which have to be compared to thresholds set by the responsible authority. Failing to comply may cause a project to be delayed and thus lead to additional costs. The precautionary principle...

Sanitation, as described by the World Health Organization (WHO), refers to the provisions of facilities and services for safe disposal of human urine and faeces. On the outset of the 21st century, 40% of the world’s inhabitants do not have access to sanitation facilities and still rely on a bucket, a bush or a backstreet for excretion....

Random wave and current forces acting on an offshore structure, cause random base shear forces in time. The peak base shear is the maximum value of base shear that occurs during the passage of a wave. The extreme base shear is the maximum value of base shear that occurs within a period of time, say one hour. So far, the distributions of extreme...

Congestion on the Dutch motorway network is an actual problem, which originated over the past decades. Over the past few years, the extent of congestion is decreasing, though still very significant. Road authorities therefore show interest in traffic congestion forecasting. In this way they can inform road users or undertake other strategic...

In hydraulic engineering it is known that for the evaluation of the performance of a system, a probabilistic approach is preferable to a deterministic one. The essence of such a probabilistic approach is that random variability/uncertainty is explicitly taken into account. In this graduation project, this probabilistic way of looking at a system...

During the past years a lot of attention has been drawn towards the development of renewables, due to the expected depletion of fossil fuels and political decisions. Offshore wind energy is considered as one of the most promising renewable energy sources, however the cost of offshore wind farms have not yet reached competitive levels. Hence...

In this research the reliability of dikes are studied that are influenced by the presence of buildings. Along many Dutch dikes (residential) buildings are present. These buildings may influence the reliability of the dike positevely and or negatively. In this study a probabilistic method is developed to determine the influence of a building,...

Dutch national highway bridges have to cope with increasing traffic loads, causing steel bridges built in the 1970’s to suffer from fatigue problems. As a consequence there were assessments needed throughout the last decade to ensure safety. The resistance (strength) is relatively well understood compared to the loads that a bridge is subjected...

Robustness has recently become a popular term in structural and hydraulic engineering. However, the concept of ‘robust design’ or ‘robustness’ has no clear definition. The aim of this thesis was to find a definition for a robust system and to use this definition to search for an added value of robust design in structural engineering. The...

Large capital and maintenance dredging operations are required to ensure the accessibility of many ports. The expenses associated with the dredging operations can have a significant impact on the finances of these ports. Therefore, considerable attention to the design of the width and depth aspects of access channels is justifiable. This study...

During this research a method is developed for finding the cost optimal design of a sea dike when a probabilistic method is being applied and flexibility is allowed in the distribution of the total failure probability over the various failure mechanisms. A probabilistic model has been set up to calculate the cost optimal design for a sea dike...

In dit rapport wordt een probabilistisch (diepte-) ontwerp gepresenteerd voor het binnengebied van de haven van Rotterdam. Ook worden de mogelijke faalmechanismen (bodemberoering en verminderd manoeuvreerbaarheid) bestudeerd. Als referentie modellen zijn bestudeerd de modellen Harap en Protide van Rijkswaterstaat, en CADET van US Army Corps of...

Design water levels are a basic concept in flood risk management practice. These water levels with a specified return period are used for the design of dikes and other flood protection measures along the river Meuse. Current practice is that these water levels are determined by hydrodynamic simulation of a standard design hydrograph at the...

More than five years after Hurricane Ike devastated the Galveston Bay Area, the most critical challenge remains; reducing flood vulnerability. In response to Hurricane Ike’s disastrous impact, several structural flood risk reduction strategies have been proposed. Some advocating local solutions, others advocating system-wide coastal barriers....

The potential ecological effects of the sand mining activities for Maasvlakte 2 have been identified in an Environmental Impact Assessment (EIA). One of the identified effects in this EIA was an impact on the number of sea ducks in the Natura 2000 area 'Voordelta'. The sand mining activities will cause an increase of the silt concentration along...

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....

This research follows a fully probabilistic approach in order to estimate the optimal design for a river dike cross-section, taking into account the investment costs. From the theory studied, the failure mechanisms that contribute most to the failure of river dikes are identified. These are overflowing, wave overtopping, piping and inner slope...

The main research objective of this study is to gain more insight into the uncertainties that are occurring in maintenance projects. A lot of research has already been performed on the subject of budget overruns in large scale new development infrastructure projects, however, information on budget overruns in maintenance projects is lacking....

The increasing demand for electricity offers many opportunities for renewable energy production, of which one alternative is tidal stream energy. Several feasibility studies have shown that the global tidal stream energy potential can contribute significantly to producing renewable energy. This tidal energy can mostly be produced at the 'tidal...
