Sand ripples are small (10 cm height) bed forms which occur in the nearshore and surf zone under the impact of both waves and currents. They impact the roughness of the bed used in models of this zone, and contribute to sediment transport. Predictions of their geometry are important to properly model roughness, so correlations between the waves...

The Sand Engine was constructed in 2011 with the main goal to enhance the natural dune growth. It is the first mega nourishment in the world comprising of 21.5 Mm<sup>3</sup> of sediment. There is a large difference between the predictions of the dune growth (25 ha in 20 years) and the actual measurements (1 ha in 4 years). Therefore a more...

A mega-feeder nourishment is a concentrated nourishment that disperses over time due to wind, waves, and tide, and as a result ‘feeds’ its adjacent coasts. During the design phase of a nourishment, performance indicators can enable an objective comparison of a mega-feeder nourishment to alternative nourishment strategies, In the case of an...

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...

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....

Sand replenishments, or nourishments, have been the prevalent strategy of the Netherlands for coastal protection since 1990. In consideration of the expected sea level rise and potential increases of storm surges as a result of climate change, an innovative pilot project known as the ‘Sand Engine’ has been implemented. In contrast with...

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...

Relative sea level rise and climate change, but also the migration of the growing world population to the coast, continuously increase the pressure on the coastal system. In combination with the increased awareness for sustainability, the interests in the coastal zone become integrated and complex. Integrated Coastal ZoneManagement (ICZM)...

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...

Recently an innovative nourishment method has been applied as a counter measure for coastal recession in the Netherlands. This soft engineering solution, also known as the Sand Engine, consists of a shoreline perturbation of $21.5$ Mm\textsuperscript{3} sand which will be redistributed along the shore by the natural forces of waves, tides and...

The study presents an assessment of sustainable practices for applying sand nourishments aiming long term coastal protection and development. Such concepts are applied in three study cases: Sylt (Germany), S'Abanell (Spain) and Ghanaian coast.

The goal of a sediment tracer is to give quantitative or relative feedback on (coastal) morphological changes or track either sediment or other particles (e.g. contaminations) in sediment dynamic environments. A sediment tracer is a visible or invisible marked (sediment) grain that is artificially injected or is present in-situ. This Master...

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...

This thesis presents the application of an aeolian transport model used in desert environments [Sauermann et al., 2001, Kroy et al., 2002] as a tool for the evolution of coastal nourishments. This study will try to investigate the driving processes in the model and adapt or extend the model application to the coastal system. If we want to apply...

In September and October of the year 2009, three sandgroyne nourishments have been executed at the Delfland Coast near the village of Ter Heijde. The nourishments have been executed to restore the sediment buffer in the upper part of the coastal profile. A sandgroyne is a concentrated amount of sediment (200.000m3) artificially nourished from...
