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,...

Wave-Driven Set-Up of Fluid Mud: Demak, Indonesia

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...

Maintenance dredging in the Port of Rotterdam: A research to the increase in maintenance dredging volume at Port of Rotterdam

The Port of Rotterdam (PoR), located in the Rhine-Meuse estuary, is subject to sedimentation. In order to keep the port accessible for vessels with high drafts, maintenance dredging works are done. The maintenance dredging over the port area is executed by two parties, PoR itself regarding the harbour basins and Rijkswaterstaat (RWS) regarding...

Sediment pathways in San Francisco South Bay

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 role of mud on the long-term morphological development of a tidal basin

Assessing the Influence of Suspended Sediment on Effective Hydraulic Roughness from Tidal Damping Aspect: A Study Based on Yangtze River Estuary

The objective of this project is to assess the influence of suspended sediment on hydrodynamic properties in the study area from tidal damping aspect. Firstly, through conducting tidal amplification factor analysis based on real time measured data, seasonal variation in sloping tendency has been observed. The difference in sloping tendency...

Suspended Sediment and Light Attenuation Characteristics in Singapore Waters

Light is attenuated by materials present in the water column by scattering and absorption. The knowledge of light attenuation and its contributing factors influencing visibility/turbidity is unknown in Singapore waters. This MSc thesis consists of field measurement, laboratory experiment and numerical modelling in 3 parts; parameterisation of...

Fine sediment transport near coral reefs islands in the Singapore Strait

The objective of this study is to determine large scale of fine sediment transport near coral reefs islands in the Singapore Strait. Coral reefs in the Singapore Strait face great pressure due to high sedimentation and turbidity, which cause decreasing of light penetration and of environment quality for the coral growth. Sedimentation and high...

Coastal Erosion Processes near sea dikes in Hai Hau district, Vietnam

The erosion problem in Hai Hau coastal district (Vietnam) is the subject of this thesis. The exact processes that drive this ongoing erosion however are not well defined yet, and therefore two main goals are defined. The first goal is to gain more insight into the processes that drive the ongoing erosion in Hai Hau. The second goal is to predict...

Morphodynamics Suriname River: study of mud transport and impact due to lowering the fairway channel

inland transportation of goods. The artificial fairway channel provides entrance to the port of Paramaribo and Paranam. The motivation for this thesis project is the intention of lowering the fairway channel to increase the navigable depth, to create a cost-effective fairway for the bauxite and alumina transport activities. To obtain the...

Hydraulic roughness in sediment-laden flow

Most estuarine, and some coastal, areas are characterised by large amounts of fine-grained cohesive and non-cohesive sediments. At sufficiently high concentrations, sediment transport in suspension may significantly influence the hydrodynamics. In sediment-laden flow with concentrations of approximately, stratification may occur due to a...
