Scheijmans, Jasper (author)
The Netherlands has 254 km of coastline that is covered with sandy dunes. As these dunes function as primary flood defences, intensive research has been conducted into dune erosion in recent years. This research mainly took place in laboratories, because all boundary conditions could be controlled and measurements could take place very...

The Sand Engine is a new innovation in coastal protection, a mega feeder nourishment. This pilot project was constructed in 2011 along the Delfland coast, which is historically prone to erosion. Since its construction, the Sand Engine is intensively being monitored to track the morphological development.<br/><br/>The objective of this thesis is...

This document describes a study into the influence of alongshore bathymetric variability on currents which form a risk to bathers. Changes to coastal zone management along the Delfland Coast have given rise to questions on the influence of alongshore bathymetric variability on bather risk. Extensive measurement data is available from two...

The Sand Motor is a unique and dynamic solution for coastal erosion, aimed at distributing the nourished sand along the Delfland coast. Besides enhancing coastal protection, the Sand Motor has been designed to also provide opportunities for recreation and nature development. The contributions of ecosystems to human well-being, that arise from...

This study has as main objective to `make recommendations for improvement of the objective evaluation of the effectiveness of the Sand Engine'. The Frame of Reference methodology, a tool developed by Van Koningsveld (2003), is used to map the evaluation of effectiveness. This approach is used descriptively as well as prescriptively. A...

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...

This study investigates the existence and character of tidal flow separation at the Sand Motor, a mega-scale sand nourishment at the Delfland coast. Tidal flow contracts at the tip of the Sand Motor, downstream the tip the flow diverges and flow separation could occur. In case of flow separation the diverging streamlines cannot follow the...

The aim of this research was to develop an interdisciplinary framework suitable for engineering purposes that connects natural processes such as wave propagation, aeolian transport, oxidation process or chemical reactions with associated critical measurable (a)biotic parameters like a rip current, beach width, canopy height density, salinity...

Van Gils, A. (author)
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...

The sediment composition of the sea bed is of relevance for various coastal properties such as bed forms, beach slopes and marine ecology. Furthermore it may significantly influence the morphological evolution of the coast. Knowledge about the processes forcing the spatial distribution of a certain grain size is therefore of great importance....

Stam, G.N. (author)
Recently, nourishments have been carried out on a large scale to counteract the on-going erosion along the Dutch Coast. The main advantage of these large beach extensions is that large stretches of coastline are protected for a long time scale (e.g. 20 years), which decreases the frequency of nourishing significantly. This is not only cost...

Beach state classification, though simple in its concept, is difficult to be distinctly and accurately applied in some real life situations. The issue is further compounded when it is applied to mega- nourishments which, in essence, are morphologically different in terms of an artificially-formed beach versus a naturally-forming beach. Yet,...

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...

A new approach in coastal maintenance is the application of a large scale nourishment as natural feeder of the coast. The Sand Motor constructed near Kijkduin on the Holland Coast is a pilot project of this new nourishment strategy. The objective of this research is to contribute to a better understanding of the sediment transport processes at...
