Coastal Erosion Mitigation at RN90: Integral approach to Erosion Mitigation along the Caribbean Coast of Colombia

As a result of increased economic development in Colombia, the pressure on the natural system has increased. The export of natural resources through international ports at both the Pacific Ocean and Caribbean Sea causes conflicts between infrastructure and the dynamic behaviour of the coastal system. This Master Thesis focusses on the bay...

Project South Durban: Understanding the Sediment Transports and Budgets around the Durban DigOut Port, South Africa

Durban is located on the east coast of South Africa in the province of KwaZulu-Natal. It is one of South Africa’s biggest cities and has one of the busiest ports in Africa. To maintain Durban’s current economic position the Durban Port has to expand, which is problematic due to a lack of space. A solution is to develop a completely new port: the...

Global Assessment on the Lifetime of Mega Nourishments

Recently an innovative nourishment method has been applied as a counter measure for coastal recession in the Netherlands. This soft engineering solution, also known as the Sand Engine, consists of a shoreline perturbation of $21.5$ Mm\textsuperscript{3} sand which will be redistributed along the shore by the natural forces of waves, tides and...

Modelling sediment sorting near the large scale nourishment 'The Sand Motor': Understanding cause and impact of sediment sorting processes

The sediment composition of the sea bed is of relevance for various coastal properties such as bed forms, beach slopes and marine ecology. Furthermore it may significantly influence the morphological evolution of the coast. Knowledge about the processes forcing the spatial distribution of a certain grain size is therefore of great importance....

Evolution of beach extensions: Numerical modelling of large scale nourishments using UNIBEST & Delft3D

Recently, nourishments have been carried out on a large scale to counteract the on-going erosion along the Dutch Coast. The main advantage of these large beach extensions is that large stretches of coastline are protected for a long time scale (e.g. 20 years), which decreases the frequency of nourishing significantly. This is not only cost...

Assessment of beach states at the Sand Motor on the basis of alongshore variability in bathymetry data

Beach state classification, though simple in its concept, is difficult to be distinctly and accurately applied in some real life situations. The issue is further compounded when it is applied to mega- nourishments which, in essence, are morphologically different in terms of an artificially-formed beach versus a naturally-forming beach. Yet,...

Sediment sorting at a large scale nourishment

A new approach in coastal maintenance is the application of a large scale nourishment as natural feeder of the coast. The Sand Motor constructed near Kijkduin on the Holland Coast is a pilot project of this new nourishment strategy. The objective of this research is to contribute to a better understanding of the sediment transport processes at...

Coastline modelling with UNIBEST: Areas close to structures

Coastline modeling with UNIBEST: Areas close to structures In the world of coastline modeling there are several ways to predict coastline development. One of those is with the use of single line modeling software. This kind of modeling is rather basic, straight forward and fast, but it lacks some detail of different processes taking place....
