The application of a continuous nourishment in a tidal inlet system: Case study Ameland Inlet

There is a demand by Rijkswaterstaat for CO2-neutral sustainable methods and technologies to maintain the Dutch coastline. The Zandwindmolen is a fixed CO2-neutral dredge, transport and nourishment concept that nourishes sediment continuously. The purpose of using a Zandwindmolen is to provide the entire surrounding area where the Zandwindmolen...

Sediment Pathways on Ebb-Tidal Deltas: New Tools and Techniques for Analysis

In an era of rising seas and other challenges posed by climate change, coastal regions like the Netherlands are facing ever graver threats. Strategic sand nourishments could mitigate the threat of coastal erosion and sea level rise on barrier island coasts while limiting ecological impacts. However, insufficient knowledge of sediment transport...

Assessing beach width dynamics through earth observations

Coasts are constantly under the pressure of hydrodynamic conditions such as waves, tides, and storms. In the Netherlands, sand nourishments are executed every few years in order to maintain the country’s sandy beaches for purposes of safety, recreation, and ecology. In order to determine where to carry out these nourishments, the whole sandy...

The application of a continuous nourishment on wave and tide-dominated systems

The Sandwindmill system could decarbonize the Dutch coastal protection whilst harmonizing with the building with nature approach. The system consists of a pipeline connecting an offshore borrow location to a nearshore area, where the mined sediment is discharged. The equipment is powered by wind turbines. As long as the wind blows sufficiently,...

A New Design for the Scheveningen Pier

The current owners of the Scheveningen Pier are starting to head into the second phase of their exploitation plan, which is to replace the current pier. This new pier is larger than the current pier and can exploit at a higher level. This thesis creates a design for a new Scheveningen Pier. A design method is used, which combines the engineering...

Unravelling the sandy shorelines dynamics derived from satellite images

Coastal zones all over the world have become heavily populated and developed due to the aesthetic value and diverse ecosystem services that they provide (Luijendijk et al. 2018). In recent years, however, climate change and anthropogenic pressures have exacerbated unprecedented coastal recession, threatening billions of dollars’ worth of coastal...

Semi-Automated Monitoring of a Mega-Scale Beach Nourishment Using High-Resolution TerraSAR-X Satellite Data

This paper presents a semi-automated approach to detecting coastal shoreline change with high spatial- and temporal-resolution using X-band synthetic aperture radar (SAR) data. The method was applied at the Sand Motor, a “mega-scale” beach nourishment project in the Netherlands. Natural processes, like waves, wind, and tides, gradually...

Lecture notes ct5309. Tides, currents and water; coastal problems; sediment transport processes; coastal transport modes; longshore transport; cross-shore transport; fundamentals of mud; channels and trenches; coastal protection; application of structures; application of nourishments.

Het effect van brandingsruggen op de kust van Egmond aan Zee

In dit onderzoek wordt een gedeelte van de Hollandse kust beschouwd, namelijk het kustvak nabij Egmond aan Zee. In dit kustvak doet zich een vreemd verschijnsel voor; wanneer de mate van kustvooruitgang en kustachteruitgang langs de kust wordt uitgezet blijkt een golfachtig patroon op te treden met een kenmerkende golflengte van 2 km. Verder...
