Shanghai is one of the numerous megacities worldwide that experience severe flood events triggered by torrential rainfall. To deal with the undesirable consequences of these events and mitigate the flood hazard, the research of flood reduction measures is necessary. In this effort, the hydrodynamic modelling is a useful tool.<br/>In this master...

Siltation affects navigation in harbors and waterways by reducing the water depth. To regain depth and safeguard navigation, dredging is required. Water Injection Dredging (WID) is one of the available hydrodynamic dredging techniques, in which pumps on a vessel inject water at high flow velocities and low pressure into the bed and fluidize the...

All over the world coastal communities are at risk due to sea-level rise and intensifying weather conditions. Many sandy beaches are eroding as a result of human-induced factors. Currently, the preferred coastal protection measure in the United States are beach nourishments. In Europe, there also is a general shift from hard to soft coastal...

As a result of the unabated growth in plastic usage worldwide, their abundance in the marine environment has steadily increased over the last few decades. Nowadays, plastic litter is observed across all oceans and shores. Due to their wide spread and adverse effects on ecology, economy and potentially human health, plastic pollution has been...

The Rhine Region of Fresh Water Influence (ROFI) is a shallow frictional river plume in front of the Dutch coast. Each tidal cycle a new tidal plume front with fresh-water is released. Recently, internal gravity waves have been observed in this plume. Using a Froude number analysis, support for the internal wave generation mechanism by a tidal...

Coastal bays in the Caribbean accommodate different marine ecosystems, including seagrass meadows and coral reefs, which provide important ecosystem services. However, these marine ecosystems are endangered. Seagrass ecosystems have a key role in coastal bays, but despite their alarming rates of loss, they receive little attention compared to...

The Bollen van de Ooster, in this report referred to as the Ooster, is a sand bar in the outer delta of the Grevelingen. The Ooster is separated from the coast by a relatively deep channel, called the Schaar. Closure of the Grevelingen in 1971, with the construction of the Brouwersdam, initiated vast changes in morphology. Damming of the estuary...

Hurricanes impose great threats on coastal communities in terms of hazard and impact. Recent hurricanes like Harvey (Texas, 2017) and Idai (Mozambique, 2019) emphasize the global character of this threat. In the U.S., Hurricane Harvey tied with 2005's Hurricane Katrina as the costliest tropical cyclone on record, inflicting $125 billion in...

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...

In Chile, the Biobío river separates the cities of Concepción and San Pedro de la Paz. Bridges crossing the Biobío river ensure a fast and dependable connection, which contributes to the transport options in the region. With the Biobío region being the second largest contributor to the country's GDP, an unreliable transport network is highly...

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...

In submerged conditions groynes add resistance to a river, thereby increasing the water levels for a particular discharge. Groynes are modelled in two ways, either they are included in the bed topography when the grid resolution is sufficiently high or with a sub-grid parametrisation when the grid cell-size is larger than the geometry of the...

Like many rivers around the world, the Loire river in France has a history of human interventions in order to facilitate navigation and port development. Next to affecting bed levels directly, the heavy modification of the river-estuary has induced significant changes in the hydrodynamic and morphodynamic behaviour of the Loire. As a result, the...

In this additional thesis a 2D urban flood model in the downtown area of Shanghai was investigated. Therefore a numerical model of Delft3D flexible mesh (DFM) was used. Since the model was investigated from scratch, a lot of data analysis and pre-processing was required to have reasonable input data. As input data a surface elevation map, a map...

Process-based method forward stratigraphic modelling provides advantages in reservoir modelling by simulating the geological process mathematically, and the genesis of geologic formations over time (Michael et al., 2010). In spite of its advantages, Miller et al. (2008) have recognised significant challenges in process-based simulation models,...

Shallow bays in the Caribbean, like Baie Orientale and Baie de L'Embouchure in Saint Martin, are often sheltered by coral reefs and covered by seagrass meadows. They provide valuable services as tourism and coastal protection. The ecosystems are linked through biological, chemical and physical processes. But they are under pressure due to sea...

Over the last decades, the People’s Republic of China experience large economic development, which have led to severe shortages of usable land. To counteract this, the Chinese central government promoted the development of coastal provinces by reclaiming large sections of coastal zones. One of these regions is Nantong Binhai Park or Tongzhou Bay...

Traditional reservoir modelling utilizes a stochastic approach centered around statistics to generate a 3D representation of the reservoir. While the results of a stochastic approach are favorable, they tend to lack the detail that is necessary to fully understand the different aspects of the reservoir, more precisely, the inclusion of...

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...

Seagrass meadows are essential and valuable to many shallow coastal ecosystems, due to the many important ecosystem services they provide. The interaction of feedbacks between hydrodynamics, sediment dynamics, and eelgrass can be described with a feedback loop. At locations where eelgrass is present, it favours its growth by modifying the local...
