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...

In many coastal seas, wind-generated waves produce a strong bottom orbital velocity which stirs up sand from the bottom. This process strongly influence sediment transport and bottom evolution. State-of-the-art morphodynamic models traditionally represent the stirring of sand by irregular waves in a highly parametric way. For instance, the...

The maximum wave run-up on a beach is an important factor in the design of coastal protection measures. Therefore, it is desired to predict this run-up based on numerical models. In this thesis, this is done with the use of the model XBeach. Wave run-up consists of multiple components: a swash height, S, and a wave set-up, <η>. The swash height...

The purpose of this study is to identify the hydrodynamic effects of the dredging works and stationary making of the El Palmar island in 2015. The most critical parameters include wet/drys season, sediment characteristics and tides. This study makes use of a model constructed in DELFT3D. The model is used to show both the hydrodynamic and...

Coastal inundation models are benefited by timeliness of the predictions, not only when it comes to real-time forecasting but also considering risk assessment studies and sensitivity analysis. Numerical models however are often subjected to a trade-off between accuracy and efficiency, especially when dealing with large geographic scales. In this...

This thesis investigates the governing generating mechanisms, shoaling and reflection behaviour of infra-gravity waves on a mild-sloping, macro-tidal, rocky shore platform. The methods comprise among others, field data analysis of the Lilstock platform, numerical modelling using a calibrated XBeach model and a cross-correlation analysis to...

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...

In 2011 the Sand Motor was realised at the coast of the province of South-Holland as a pilot project combining different functions such as safety, recreation and nature development, following the philosophy of Building with Nature. The idea was to create a mega nourishment that would supply the coastal system between Hook of Holland and...

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 Dutch Flood Defense Act prescribes the assessment of the safety level of Dutch primary sea and flood defenses every six years. To asses if the required level of security of the sea and flood defenses is guaranteed, first the Hydraulic Boundary Conditions (HBC) which the sea and flood defenses are exposed to, have to be determined. At the...

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,...

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...

Rip currents are narrow, seaward directed flows in the surf zone that can pose a serious threat to swimmers. This issue has received attention particularly on swell dominated coasts (such as the US, Australia, France and UK) where numerous field experiments have been undertaken. However, the threat of rip currents is less recognised on wind-sea...

Artificial beach and foreshore nourishments, as executed widely along the Dutch coast, change the nearshore morphology and current patterns significantly. Over the last decades the size of the nourishments has increased from 0.7 x 106 m3/km to over 6 x 106 m3/km. Groynes which were present along the southern Holland coast since the 19th century...

Infragravity waves are a common feature in the nearshore wave field and have a significant impact on numerous coastal processes. It is therefore important to accurately predict infragravity wave conditions at a given location. However, analytical relations do not exist with which to make such predictions and one has to rely on numerical models....

The focus is on the numerical flow model TRIWAQ. It is developed as a hydrostatic free-surface flow model, which is currently being used by the KNMI and Rijkswaterstaat for predictions of water levels in the North Sea and Dutch estuaries. TRIWAQ has successfully been extended to the realm of nonhydrostatic modeling, TRIWAQ-NH, this allows the...

The objective of this study is to analyze and simulate the behavior of a non-equilibrium profile in a storm event, in particular, the Maasvlakte-2 (MV2). The MV2 is a large reclamation project at which both soft and hard sea-defenses are applied. Soft sea-defenses exhibit steep initial profiles during construction. Understanding how this sea...

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...
