Echosounders are used to monitor suspended sediment concentrations (SSC) in coastal management studies and to monitor dredge plumes. Due to the dependency on sediment properties like particle size, shape and density, performance of single frequency measurements is limited when sediment properties are changing.<br/><br/>Using multi-frequency...

The port of Rotterdam is located within the Rhine-Meuse estuary where a substantial amount of fine sediment transport takes place. Therefore, the port of Rotterdam is subject to significant siltation, requiring maintenance dredging to guarantee a sufficient nautical depth of fairways and harbour basins. To optimise the dredging strategy in the...

Canal Emilio Mitre is a navigation channel that runs through the Rio de la Plata estuary in South America. It grants access to the second largest inland waterway system in South America, covering (parts of) Argentina, Uruguay, Brazil, Paraguay and Bolivia. The channel is a main bottleneck for navigation for two reasons; the channel has a...

Relative sea level rise and climate change represent long-term threats for the ecosystems and flood defence system in the Wadden Sea. Moreover, the flood-dominant tidal basins in the area lead to sedimentation in the navigational channels used by the ferry services that connect the mainland to the Dutch Wadden islands. This report provides flood...

This report describes and analyses small scale plough process. This research is initiated by Deltares and the Delft University of Technology as an experimental way to gain insight in the ploughing of the river bed in rivers. The main target of this thesis is to gather information on the plough process as applied in the maintenance of the Waal...

River systems are vastly changing environments, not only due to natural process, but also human intervention plays an important role. With the many different river functions at play, large amounts of maintenance budgets are associated with river management. For decision makers it is important to know expected costs or losses and the spread...

The study into sand wave dynamics in South Channel has commenced after large dune forms were observed in monitoring campaigns following the channel deepening project of the Port of Melbourne. The project involved deepening of the harbour berths and channels, but more importantly, it involved the deepening of South Channel in Port Phillip Bay....

Gravity currents are common around the world, consider for instance avalanches and pyroclastic flows. The kind of gravity currents that this research focuses on occur below the water surface. During dredging operations soil is cut and transported, during many of these processes sediment is introduced into the environment. Consider for instance...

Growing concern about global warming and climate change intensified the research into more efficient ways of operation in the maritime industry. These researches triggered the use of electrical batteries in hybrid systems. Van Oord aims to operate more efficiently, which implies using less fuel and thus emitting less carbon dioxide. A way to...

The world is rapidly embracing networked technology and transitioning into one of hyperconnectivity, a term first coined by social scientists Anabel Quan-Haase and Barry Wellman. Increased connectivity provides benefits such as automation and, remote access and control of networks and equipment, thereby decreasing operational costs. Maritime and...

Roelen, S. (author)
This thesis proposes a methodology towards quantifying the uncertainty resulting from the density and spatial arrangement of samples and assessing their effect on forecasting key performance indicators, related to dredging and (wet) mining operations. Aside from quantifying this uncertainty, another objective of this research is to develop a...

Structural vibrations are a known cause of damage to offshore structures and equipment. A Cutter Suction Dredger (CSD) is a dredge vessel known to vibrate heavily during operation. Primary cause of these vibrations is the cutting process, performed to cut and excavate soil from the seabed. A component prone to damage is the cutter ladder, a...

In this research we studied the behaviour of dredged glacial till in the creation of a landfill. An experimental approach is used where we primarily focussed on the settling and consolidation characteristics. Till is in general a well graded, non sorted material and segregation during dredging and transportation can be expected. The aims of this...

There are many locations where the accumulation of mud poses a problem. In lakes it can have a negative influence on the ecological situation and in port basins it can hinder traffic. Usually these mud deposits are removed periodically with regular dredging vessels. Looking at the continuous nature of the mud deposition and at the trend of an...

The authorities of Argentina wish to improve the accessibility of the ports located in the Río de la Plata and upstream to the Paraná River. The water depth in the Río de la Plata is very shallow and did not suffice for vessels to navigate. Therefore navigation channels have been dredged. Ship drafts have increased in time and nowadays there is...

The Dutch shipbuilding industry has a real competitive force in building complex, specialized and multipurpose vessels (Rabobank, 2014). However, the Dutch maritime sector has to deal with strongly growing competition worldwide. For the dredging sector this implies the need to innovate in order to remain competitive. This research focuses on the...

Especially for the dredging industry in the United States of America and the leading dredging company Great Lakes Dredge & Dock Company the clamshell dredge is a commonly used dredge tool. The aim of this study was production [m3/s] optimization of the clamshell bucket for stiffer clays. Different aspects of clamshell bucket geometry to clay...

Over the last centuries, Dutch rivers such as the Rhine have been heavily trained for the purpose of the safe discharge of water, sediment and ice, and navigability. After the notorious flood events of 1993 and 1995 along the Rhine, new large-scale river works were initiated, such as the Room for the River (RfR) programme, to increase flood...
