Regular maintainance dredging is a large expense to the Port of Rotterdam, therefore the installation of sediment traps is considered. By increasing the bathymetry locally, an increase of local accumulation is expected and a decrease deeper in the harbour basin. This thesis describes the functioning of sediment traps in a stratified tidally...

This paper presents the mud dynamics in the harbor basin of Zeebrugge in the Southern North Sea based on an analysis of field data. Mud is typically transported into and within the harbor basin through advection of suspended particulate matter (SPM). Three important timescales have been identified. On the intratidal timescale, sediment import...

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 typically mild slopes of the muddy coastline in the south of Myanmar, enable the tide to propagate deep into the mainland, carrying muddy and saline water. The Nga Moe Yeik Creek (a tributary of the Yangon River) is closed off at the upstream end during the dry season and is subject to high siltation rates. Extensive dredging is necessary to...

Flushing basins have been used at several locations in Germany, Belgium, and the Netherlands in the past centuries to maintain the navigational depths of harbour channels. These locations are not in use anymore or are only partly responsible for channel maintenance. This thesis encompasses a study to optimize the geometric parameters of a...

This thesis investigates the origins of large sedimentation volumes in the Port of Santos, São Paulo - Brazil. The port is located in the Santos - São Vicente estuarine system, delimited by scarps and subject to intense rainfall. The terminals are placed inside the estuary and their access is provided by a 24 km long channel with mean depths of...

At the southern coast of Sri Lanka a small fishery harbour is located in Hambantota. Soon after construction of the harbour in 2006 the harbour started silting up at various places. From that point onwards the harbour’s basin has been dredged multiple times, but the problem turned out to be structural. In addition breaking waves are encountered...

Coastal erosion is greatly accelerated by the presence of agriculture and aquaculture activities (oil palm plantation or shrimp farming involving the construction of earth bunds) in the natural process. Earth bunds or dykes are constructed to prevent entrainment of seawater into the agriculture area behind the bunds so as to protect these...

The study focuses on the impact of human interventions on the natural behaviour of estuaries in response to sea-level rise. In particular it focuses on the affect of managed realignment on the critical sea level rise (SLRcrit) for the Poole Harbour. Numerical model ASMITA (Aggregated Scale Morphological Interaction between a Tidal inlet and the...

The use of pile groynes to reduce sediment exchange between river and harbour Introduction To reduce siltation in harbours located in rivers or waterways in order to decrease the high costs of dredging and maintenance of its basins, a need of searching measures to decrease the sediment exchange between river and harbour arises. Research One of...

Siltation is a serious problem for harbours situated on tidal rivers and estuaries. Maintenance dredging is necessary on a regular basis to guarantee safe navigation and is often a large cost factor. A means to prevent sediment from entering a harbour is the Current Deflecting Wall (CDW), which passively alters the water exchange at the harbour...

Many harbours in the world suffer from high siltation rates in their basins. To guarantee safe shipping, harbour authorities have to maintain the navigable depth by having dredged large amounts of mud. Some authorities relate the navigable depth to a depth at which the density is equal to a certain value, e.g. 1200 kg/m3. However, the shear...

In scheepvaartkanalen worden er steeds meer natuurvriendelijke oevers aangelegd. Dit zijn oevers die bestaan uit een vooroever en een daarachter gelegen natte strook of plasberm. In de vooroever zitten openingen die dienen om vers water vanuit het kanaal naar de natte strook te laten stromen om ongewenste effecten van stilstaand water te...
