What are the impacts on well-being and climate change of a four-day workweek for The Netherlands?: A time-use and consumption-based scenario analysis of the impacts of a four-day workweek

The time we spend on activities has consequences for consumption and related emissions. A four-day workweek is assumed by some to have an improved effect on well-being and reducing emissions, however, the consumption from additional leisure time could counteract the benefits. Therefore, this research looks at the impact of a four-day workweek on...

Simulating wave attenuation by an offshore floating solar system

Because the demand for green energy increases rapidly, it is expected that solar and wind energy will dominate future power generation. New in this field is the development of offshore floating solar systems, consisting of multiple interconnected platforms that are covered with PV panels. Besides satisfying the demand for electricity, these...

Wave Climate and Coastline Response of the Dutch Coast: Investigating the effect of large-scale offshore wind farm developments in the North Sea

To counteract the effect of climate change, a global agreement was put into force in 2016, aiming to limit the increase in average global warming and reduce greenhouse gas emissions. In that respect, European countries are investing in cleaner sources of energy and predominantly offshore wind, which has seen a rapid growth over the last years....

Numerical modelling of the migration direction of offshore sand waves using Delft3D: Including underlying seabed topography

The growth of the offshore wind industry results in intensive usage of the sandy seabed in the North Sea, currently and in the coming decades. Large-scale bed forms are present in shallow seas with sandy beds such as the North Sea. The most dynamic bed forms are sand waves. Due to their dynamic behaviour, sand waves can interact within offshore...

Validation of X-band radar-derived current measurements at the Sand Engine: The relation between spatial scale of wave dispersion analysis and accuracy

Monitoring of coastal hydrodynamics over a relatively large spatial extent and a long temporal period is essential to assess the impact of coastline interventions on several functions. An example of a recent coastline intervention is the Sand Engine, a pilot project for optimization of (future) coastline maintenance. This innovative pilot...

The Accuracy and Error Sources of Radar-derived Bathymetry by the XMFit Algorithm

The coastal bathymetry is one of the most essential inputs for understanding, monitoring and modelling the coastal environment. A remote sensing technique called marine radar may overcome disadvantages of present monitoring techniques and has the advantage to obtain measurements with a high spatial and temporal resolution. A Fast Fourier...

Numerical modelling of the growth of offshore sand waves: A Delft3D study

Offshore sand waves of several meters high and hundreds of meters long are formed in shallow seas due to the tidal currents. These sand waves can, amongst others, influence the burial depth of cables of offshore wind farms and obstruct navigation channels. For the Far Large Offshore Wind programme (FLOW), one of the goals of Deltares is to...

Validation of X-Band radar derived hydrodynamic phenomena

The coastal area is a dynamic environment that suffers from human interventions and climate change. This requires extensive research and monitoring of the coastal areas. Measurement systems play a key role in the monitoring. Current velocities are for example often measured to investigate local hydrodynamics. At the moment the ADCP is often used...

Development of an X-band Radar Depth Inversion Model at the Sand Motor

A large-scale nourishment known as the Sand Motor has been implemented along the Dutch coast as a Building with Nature solution designed for the upcoming 20 years. Given the long-term period of the project, a combination of in situ measurements and remote sensing techniques are currently in use. An X-band radar system is deployed at the Sand...

Understanding and modeling the process of resuspension of fines in the coastal zone; case Khalifa Port

=Introduction= Worldwide there is an increasing amount of dredging activities, due to increasing demand for transport of goods over the world. These project are more and more near sensitive nature reserves and thereby a potential threat of biodiversity; which is a major concern for port developers, authorities, environmental organizations and...

Convex coastline induced rip currents at the Sand Engine

This study investigates the hydrodynamics at a convex coastline. The Sand Engine, a man made peninsula in the Netherlands, is used as a case scenario. It is hypothesized that a rip current can develop under certain wave conditions due to the change in coastline orientation. The main goal of this research is to obtain a better understanding of...
