Rijkswaterstaat and the Dutch contractors have many years of experience in the removal of silt and sand from the Rotterdam harbour. In all those years a great deal of valuable experience has been gained with the behaviour of silt in the harbour. They never succeeded, however in making an estimation/prediction of the amount of sedimentation which...

The city of Itajaí is located in the province of Santa Catharina in Brazil. The people of Itajaí have been coping with flood risk for the past decades. During normal conditions the Itajaí-Açu River is a rather calm river that is used for navigation and the harbour area. Recovering from the past two floods in 2008 and 2011 have cost more than...

Sedimentation in reservoirs is a consequence of constructing a barrier in a flowing river, which results in a decrease of the transport capacity of the river. The storage capacity of the reservoir decreases due to the accumulation of sediments and the river downstream starts to erode due to the disturbance of the sediment balance. Water...

Despite the many positive effects of dams, they can also have several negative impacts on natural systems. One of these impacts is the decrease in sediment inflow towards the coast which can lead to coastal erosion. <br/>A technique that can be applied to improve the situation downstream is modifying the discharge through the dam. Unfortunately,...

Problem definition The city Mar del Plata has one of Argentina's largest ports and biggest seaside beach resort. After the construction of the port, a steadily growing sandbank appeared in the port entrance and considerable erosion occurred on the northern beaches. To warrant the accessibility of the port, frequent maintenance dredging is needed...

Van Leeuwen, Y.B. (author)
Maintenance dredging, as a result of port and channel sedimentation, can have a large share in overall maintenance costs of a port. A smart design can minimize the amount of maintenance dredging and thus improve the profitability of a port but also the long-term sustainability. As the preliminary design stages are often decisive for the final...

As one of the most fast growing species on earth, microalgae provides great potential to satisfy the ever increasing demand in food, energy and material in a sustainable way. The focus for this thesis work is on one of the most important bottle neck of microalgae harvest process: microalgae dewatering, by CFD modeling of the flow and...

Clay particles, known for their adhesive properties, are commonly encountered in underwater soils. When producing large quantities of sand by means of dredging, fines are a byproduct and cause important viscosity changing effects altering the sand settling behavior. Much is already known in this field but knowledge lacks in the area where sand...

At the Cao Jing district in Shanghai, China, a landreclamation project is planned. The object of this project is to stimulate the natural process of sedimentation. This report comprises the results of a study concerning the optimum lay-out of dikes in the reclamation-area (see Fig. 0.1 and 0.2). In this report particularly the influence of 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...

Since coined in 2011, socio-hydrology studies have been dominated with mathematical models developed by mostly hydrologists, which often did not take social aspects into account so seriously. Some people argued that more attention into the social part of socio-hydrology should be given, because often the social aspects were too oversimplified....

Siltation of harbour basins and navigation channels is a serious problem in the port of Rotterdam as well in many other harbours all over the world. Due to siltation, basins and channels require frequent maintenance dredging to guarantee safe navigational depths. The costs associated with these dredging activities are quite high. To keep the...

Due to the predicted impacts of climate change on the frequency of storm events, water managers are challenged to improve and adapt the current urban infrastructure. Cities need to be able to deal with the adverse effects due to more frequent and heavier rainfall. This implies the need for sustainable urban drainage systems (SUDS) that can deal...

Embedding of subsea pipelines for protection purposes is usually done in a ‘Trench – Install – Backfill’ operation. The pipeline can also be embedded after it is installed on the seabed. This method is called post-trenching. When using a trailer suction hopper dredger for post-trenching, a large water jet erodes the soil underneath the pipe...

In the face of rising waters and increased stormrelated flooding, communities will have to decide what to do with their flood-prone areas. Continually repairing storm damages and providing services to these vulnerable neighborhoods demands significant government resources. For these areas, cities have three major options to consider: keep water...
