This is not the main report, but the partial report. Portugal has a coast of approximately 800 km containing a lot of interesting coastal phenomena, such as estuaries, land spits, rock coasts, lagoons, cliffs and rias (areas af sandbanks and canals in open connection with the sea). Also a lot a different harbours can be found along this coast....

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...

Om flora en fauna de kans te geven zich langs scheepvaartwegen te vestigen en voort te planten zijn natuurvriendelijke oevers nodig. Voor kanalen is een speciale natuurvriendelijke oever ontworpen : de natte strook. Tijdens onderzoeken naar het functioneren van de natte strook is een verondieping hiervan geconstateerd, hetgeen, in verband met...

Vermindering door aanpassing van de vormgeving van jachthavens 't Steel en la Bonne Aventure. Jachthavens aan rivieren slibben steeds verder dicht. AIs gevolg hiervan lopen de kosten voor het beheer van een dergelijke haven zo hoog op dat enkele havens misschien zelfs moeten sluiten. Daarom is er landelijk een onderzoek gestart om te bezien of...

In this study the river migration model MIANDRAS has been applied to simulations of the planform changes of the river Allier, a tributary of the river Loire in France. The Allier is a very dynamic and natural river system with braided and meandering river sections. Two meandering reaches of the Allier, located between Varennes-sur-Allier and...

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...

Fairway Maintenance of the river Ijssel The inland trade is a very important economical activity in The Netherland. Therefore to maintain and improve waterways is a common activity. The main problems that threaten the safety in the shipping are the erosion and sedimentation on the banks, especially in the bend banks. So some studies are...

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 Lai Giang inlet located in Binh Dinh province incorporates various features of the estuaries in the Central part of Vietnam. Belonging to the micro-tidal and wave-dominant coast and influenced by the monsoon regime, the inlet has a seasonal character. During the dry season, as the river flow diminishes, the wave action causes high level of...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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,...
