The influence of bivalve shells, of different shapes and sizes, on current-driven sediment transport: Experimental flume study

In the Netherlands, the coastlands act as the principal protection against the sea. Without human interventions, the Dutch coast would be eroding due to an imbalance in the sediment budget of the coastal zone. The preferred coastal management strategy is sand nourishment, which have become larger in scale and more complex over the last 70 years....

On the Effects of Fine Sediments in Mud Disposal Basins: Towards a better understanding of basin design by means of a numerical modeling study

The spatial and temporal behaviour of stratification in the Fehmarnbelt strait: An analysis on when and where bi-directional plume spread due to stratification can occur during dredging activities in the Fehmarnbelt

The amount of suspended sediment spill released during dredging activities in the Fehmarnbelt strait is monitored along the excavated trench to prevent negative effects on local ecology. Stratification due to the interaction of saline water from the North Sea and fresh water from the Baltic Sea forces bi-directional flow of the layer above and...

Simulation of the interception of plastic fluxes in rivers

One of the preferred features of plastic is its high durability. This merit is its main disadvantage in the natural environment. When poorly disposed of, plastic waste can enter rivers from surface waters and subsequently end up in the ocean. Here, plastic spreads out over the entire ocean and ultimately ends in ocean gyres....

Quantifying the dispersion of turbidity currents generated by seafloor mining operations

Turbidity currents are common in the waters around the world. They can be caused by earthquakes, collapsing slopes or other geological disturbances. However, turbidity currents can also be caused by deep sea mining activities. Deep sea mining is done with special mining vehicles. There are three main operations within this mining vehicle:...

Suspended Sediment Modelling in the Port of Rotterdam

This Master thesis presents an improved model for the transport of fine suspended sediment (SPM) in the Rhine region of fresh water influence (ROFI) and in the Port of Rotterdam. It is known that the transport of SPM in the Rotterdam harbor depends on marine as well as fluvial processes. SPM transport inside the harbor has been modelled in the...

The determination of the feasibility of a 'Sand Breakwater' on the Nigerian coastline at Badagry

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<br/>year. Besides these...

Research on a Subsea Separation Concept for Deep Sea Mining Purposes

Royal IHC is exploring the possibilities of a subsea separation concept for its deep sea mining concept. The most promising concept from literature was the crossflow separator, this separation concept was further researched. This to have a look at the performance of such a crossflow separator and to find out what geometry is most suitable for...

A feasibility study on constructing a flood diversion channel: Exploring the possibilities of constructing a flood diversion channel between the Mekong River and the Gulf of Thailand as measure to reduce flood risks

The yearly floods of the Mekong Delta caused by the Mekong River have been considered a blessing; it purifies the agricultural lands and deposits a fresh layer of silt on the surface, which keeps the delta fertile. However, the growing demand for agricultural products internationally and nationally has pushed the farmers to harvest all year long...
