Long-term morphological model of Poole Harbour

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

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...

Consolidation and strength evolution of Dollard mud: Measurement report on laboratory experiments

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...

Laboratory experiments on consolidation and strength evolution of mud layers

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 dredging large amounts of mud. Some authorities relate the navigable depth to the depth at which the density is equal to a certain value, e.g. 1200 kg/m3. However, the shear strength...

Sedimentation in the Maasmond: Non-linear statistics in Civil Engineering

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...

Aanslibbing van een rivierhaven: Vermindering door aanpassing van de vormgeving van jachthavens 't Steel en La Bonne Aventure

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...

Laboratory observations of the velocity field in the entrance of a tidal harbor and the exchange of heat between harbor and river

The research that has been presented in this report is a part of an ongoing study on the siltation of tidal harbors. The study deals with the water motion in the harbor entrance, which motion causes the siltation. As yet, too little is known about this complicated time-dependent water motion. The data obtained during the research will be used to...

Laboratory observations and calculations of the depth averaged flow patterns in a square harbor on a tidal river

Many harbors in the world suffer from siltation in their basins and in many cases removal of the deposited sediment leads to high costs. This siltation results from a net transport of sediment into the harbor caused by the water motion in the harbor entrance. The water motion is very complex and of a three-dimensional nature. Three main...
