Sandy barriers comprise 12% of coastlines around the world, and most of these barriers enclose tidal bays and lagoons. These systems accommodate human settlements vulnerable to climate change, which offer enough economic, social, and environmental utility to require further research on the impact of climate change and subsequent best management...

This thesis describes how the simple random walk particle model can be extended to account for sand deposition and suspension, and for particle interaction: clumping together and falling apart. The extended models are analyzed, and the corresponding partial differential equations are derived. These equations are compared to the currently used...

As the landscape of the south western river delta in the Netherlands is increasingly urbanised, the processes of urbanisation and the dynamics of nature can no longer go in their separate ways. Measures for water safety, that over the course of recent history has been diverting, regulating, and controlling natural dynamics away from the urban...

Growing markets for sustainable technologies such as solar panels, wind turbines, and electric cars require an enormous amount of raw materials that might not be available from sources on land. Exploitation of seafloor mineral resources could secure the supply of raw materials for the future. However, proposed deep-sea mining (DSM) systems will...

The Weg naar Zee (WnZ) region of Suriname’s capital Paramaribo is dealing with coastal erosion. Images from the past 30 years have shown coastal retreats of up to 1.3 km. Mangrove forest used to be present in large numbers at the location. These forests enhance accretion, but due to different reasons, the number of mangroves has decreased...

The coastal waters of Nigeria are a difficult environment to build structures to control the local morphology and hydrodynamic conditions to ones desire. This difficulty is a consequence of the persistent high-energy swell wave climate and Longshore Sediment Transport (LST) in the order of one million cubic metres per
year. Besides these...

Phenomena like urbanization and climate change will increase flooding problems, making it clear that more research and investments are needed in sewer systems to improve urban flood prevention. This research was done to determine factors influencing the sediment load to gully pots. It was assumed that in the measurement period, the retaining...

In the face of rising waters and increased stormrelated flooding, communities will have to decide what to do with their flood-prone areas. Continually repairing storm damages and providing services to these vulnerable neighborhoods demands significant government resources. For these areas, cities have three major options to consider: keep water...

The reach of the Magdalena River around the city of Barrancabermeja experiences large issues concerning its navigability since the construction of the Yondó Bridge. The purpose of this study is to investigate possible causes of this poor navigability and to come up with an improvement to the current situation. The influence of bars and scour...

Sediment nourishments have become an attractive alternative to hard measures in counteracting long-term river bed degradation. Due to the large degree of uncertainty concerning mixed sediment morphodynamics, river authorities conduct field studies to collect data that will help in the calibration of morphological models, eventually used to...

This study aims for a better understanding of the sediment pathways in San Francisco South Bay (South Bay). Many issues relevant to the Bay Area community such as shipping, recreational and commercial fishing, habitat restoration, human health, and environmental water quality are reliant on understanding sediment pathways (McKee et al. [2006])....

The main focus of this research is determining when dredging of reservoirs is feasible. First the main issues associated with the sedimentation of reservoirs are investigated. Most important are the loss of reservoir volume, sediment shortages downstream of the dam and possible blockage of water intakes.
The sedimentation issues occur mostly...

Damen Dredging Equipment is a yard dedicated to the dredging industry. The yard specializes in the design, manufacture and supply of a wide variety of dredging tools. One of the tools Damen offers is the Trailing Suction Hopper Dredger(TSHD).

The performance of such a TSHD is described by its production: the amount of sediment loaded in...

This thesis explores the nature of coastal dune behavior and the role of sediment supply in the aeolian system. The first part of the thesis conducts a data analysis based on the Dutch JARKUS dataset, which provides yearly measured profiles along the Dutch coast. A series of parameters derived from the profile measurements have been used to...

Valdivia is a Chilean city located near an estuary system, 800 km south of Santiago. The navigation capacity of the Valdivia river mainly determines the present state and future possibilities for the welfare of the city. Since sedimentation problems arose in the river, the capacity for navigation became limited. The ministry of Valdivia...

Vegetation on river banks and bars contribute to the stability of these morphological features; however, the exact processes that contribute to this stabilization are still subject to research. This study has looked into the flow phenomena at the streamwise interface between a vegetated and non-vegetated river bed. Flow velocities in vegetated...

A very common observation is the episodic erosion of beaches during storms and the slow recovery (accretion) afterwards (Yates et al. 2009). Morphodynamic models parameterize physical processes in order to relate the fluid motions (hydrodynamics) to the bed level changes (morphodynamics) over a wide range of spatial and temporal scales. Despite...

Sea level rise poses challenges to the tidal inlet systems of the Wadden Sea, including the barrier islands. If no measures are taken, the shorelines of the islands will retreat and the basins may drown. In the Ameland Inlet, the Boschplaat at the eastern tip of Ameland and Bornrif at the western tip of Terschelling are currently shrinking.

Growing interest has been expressed the last decades regarding the Late Cenozoic, gas-bearing sediments of Southern North Sea Basin. Comprising the shallow subsurface of the Dutch offshore sector, these sediments have
been deposited by Eridanos fluvio-deltaic system, draining the Fennoscandian and Baltic shield through the present Baltic Sea...

Crescentic sandbars are a commonly observed nearshore feature in coastal zones that strongly influence the surfzone circulations and are connected with the occurrence of rip currents. Furthermore, their spatial characteristics have been associated with the shoreline position in the form of shoreline perturbations, indicating morphological...
