The growing awareness of climate change asks for innovation in the methods of applying nourishments at the Dutch coastline. The concept Zandwindmolen has therefore been developed. Using wind mills at sea, sediment is dredged offshore and transported towards the shore, from where hydrodynamic and morphodynamic processes redistribute sediment...

The Port of Rotterdam has many old harbours located close to the Rotterdam city center that are no longer suitable to be used for industrial purposes. Meanwhile due to expansion and population growth of the city, more recreational spaces are needed. The idea is to use the abundant dredged material from the Port of Rotterdam to fill in and...

Demak is a regency within the province of Central Java, Indonesia, with a mud-mangrove coast bordering the Java Sea. The region is facing a rapid retreat of the coastline, threatening the livelihood of a large part of the population. The main cause of the erosion is the deforestation of the green belt of mangroves. This has disturbed the...

Accelerated sea level rise (SLR) is predicted to have multiple adverse impacts on the coastal zone, aggravating phenomena such as coastal erosion on sandy coasts. For climate change adaptation planning and informing policy, morphodynamic changes occurring at coastlines are becoming increasingly important. In this study, a calibrated Delft3D...

The project takes the increasingly polluted and flood prone coast line of the Scheldt estuary as the basis for a new coastal condition, centred on the re-composition of the sediment of the river. As a third option between dike raising and depoldering the coastline of Zeeland, a design for a new line of defence is<br/>developed which controls the...

Using an idealized width-averaged model, the influence of spring-neap cycles on the transport and trapping of suspended fine sediment in tide-dominated estuaries is investigated. To this end we introduce a multiple time scale expansion. This provides a mathematically sound argument for treating the fast ebb-flood cycle and the slow spring-neap...

In this thesis, the implementation of a passive, chipless, frequency coded Radio-Frequency Identification (RFID) tag for bedload transport studies is proposed. The proposed tag will be deployed in the semi-arid Río Colorado river, Bolivia with the aim to develop quantitative sediment transport models that relate transport to grain size. The...

Along river banks, on the transition zone between the river and see, tidal marshes can develop. The tidal marshes accommodate multiple plant and fish species. As a result of the stressful conditions in tidal marshes, unique intertidal ecology develops. However, due to the densifying of the river banks, tidal marshes are disappearing. <br/...

Seafloor characterization using multibeam echosounder (MBES) backscatter data is an active field of research. The observed backscatter curve (OBC) is used in an inversion algorithm with available physics-based models to determine the seafloor geoacoustic parameters. A complication is that the OBC cannot directly be coupled to the modeled...

Regular maintainance dredging is a large expense to the Port of Rotterdam, therefore the installation of sediment traps is considered. By increasing the bathymetry locally, an increase of local accumulation is expected and a decrease deeper in the harbour basin. This thesis describes the functioning of sediment traps in a stratified tidally...

Spaans, Lennard (author)
The beach recovery process determines the resilience of a sandy coast and is an important aspect of the coastal safety. Sediment stored underwater due to storms is transported onshore by the migration of subtidal and intertidal bars under mild wave conditions. The intertidal zone is an im-portant interface, connecting the marine and aeolian zone...

Coastal lagoon sediments are important for the biogeochemical carbon cycle at the land-ocean transition, as they form hotspots for organic carbon burial, as well as potential sites for authigenic carbonate formation. Here, we employ an early diagenetic model to quantify the coupled redox cycling of carbon, iron and sulphur in the sediments...

Increasingly large sand nourishments are used for the maintenance of sandy coasts around the world. There is, however, still very limited understanding of their behaviour (i.e. redistribution) and effects on the marine environment. This PhD thesis explores the morphological reshaping of shoreface nourishments (i.e. long bunds of sand placed at...

Due to microbial activities, the anaerobic degradation of organic matter happens in the sediments and leads to considerable gas production. Especially for low flow areas gas production is more easily fostered. To prevent the potential problems caused by gas production from the riverine sediments, this study focuses on magnitude of gas formation...

Since coined in 2011, socio-hydrology studies have been dominated with mathematical models developed by mostly hydrologists, which often did not take social aspects into account so seriously. Some people argued that more attention into the social part of socio-hydrology should be given, because often the social aspects were too oversimplified....

Within the KustGenese 2.0 research project a 5Mm3 pilot nourishment is created on the ebb-tidal delta of Ameland. For this thesis I was involved in the parties; Van den Herik, the contractor who executed the work, Deltares and Rijkswaterstaat. A tool is created to quickly analyse new surveys in combination with the ships deposit data. The tool...

The Hondsbossche Dunes is a seven-kilometre-long dune, beach and shoreface nourishment that serves as a primary flood defence since 2015. In addition to its protective function, the Hondsbossche Dunes stimulate ecological habitat development in the coastal area, in line with Ecoshape's 'Building with Nature'-approach. Its morphologic development...

Sedimentation of particle suspensions is a relevant process to a variety of applications, such as the reclamation of land and chemical engineering systems. Direct numerical simulations of the settling of a single, two and multiple solid spheres under gravity in a square duct have been performed. The simulations involve 4 different Galileo...

Mega nourishments are a novel approach to stimulating coastal safety and resilience. Mega nourishments are intended to spread along the coast on a decadal time scale by natural sediment transport processes with a minimum of intrusion into the natural coastal system. The supratidal morphodynamic behaviour of mega nourishments is not well...

High resolution maps of sandy seafloors are valuable to understand seafloor dynamics, plan engineering projects, and create detailed benthic habitat maps. This paper presents multibeam echosounder backscatter classification results of the Brown Bank area of the North Sea. We apply the Bayesian classification method in a megaripple and sand...
