To help to provide a desperately needed coastal protection strategy for the Mekong Delta in Vietnam this research looks into the possibilities for natural and sustainable coastal defence systems, including mangroves and active sediment management, such as a nourishment. The coastline of the Mekong Delta suffers from severe erosion and mangrove...

Additional thesis - Historical engineering works such as weirs, land reclamation and large scale deepening modified not only the local morphology and hydrodynamics but also tidal characteristics and sediment transport patterns in the tidal river Ems. The loss of intertidal area and ongoing deepening contribute to the flood dominance while...

This study aims to improve the predictive capabilities of flow pattern and depositional behaviour of non-Newtonian, high concentration sand and fines mixtures. The depositional behaviour influences the geometry of the deposit and the distribution of sand and fines particles, which in turn influence the strength and consolidation performance of...

The fairway connecting Holwerd and Nes forms the main transport route between Friesland and Ameland (the Dutch Wadden Sea). It consists of several tidal channels that funnel the majority of the tidal currents propagating through the tidal basin. Over the past decades, several channel bends have expanded leading to a fairway length-increase of...

Land reclamations in deltaric areas provide space to meet the demand for a safe place to live and work. Sand, a traditional filling material in some locations is becoming scarcer. An alternative filling material is mud. Mud consists of clay, silt, sand, organic material, water and gas. Therefore, it is a versatile material and difficult to...

In 2015 Georgetown, Guyana suffered from major flooding due to heavy rainfall. The use of a centuries-old agricultural drainage system for the urban drainage of the largest urbanized area of Guyana, poses problems considering flood safety. In 2016 a report was published by a ‘Dutch Risk Reduction Team’ (DRR Team) with recommendations on how to...

Due to the removal of mangrove forests, the coastal zone of Demak district has suffered from severe erosion. One of the proposed solutions to restore the sediment balance and encourage mangrove re-establishment, is the construction of semi-permeable dams. This study aims to optimise the design of such structures. A 2DH site-specific model was...

A group of islands will be constructed in the lake Markermeer to act as nature reserve for birds, called the Marker Wadden. These islands will be constructed out of soft clay, dredged from the bottom of the lake. Building with soft cohesive soils, also referred to as mud, is still a largely unknown territory. Traditionally, sand is used for land...

To date there is limited knowledge about the flow behaviour of non-Newtonian slurry and tailings flows. In hydraulic engineering and the mining industry numerous questions and uncertainties still exist. Different numerical and analytical models have been developed attempting to meet this demand. For the larger part they describe the rheological...

A demand to use mud as fill material for land reclamations has emerged over the past years. Such reclamations start with pumping a muddy suspension into an area enclosed by dikes. The particles in suspension then settle to form a mud layer, so that the supernatant can be removed. This filling process may be repeated several times to completely...

In the last century, various tidal rivers in Europe have seen a large tidal amplication, which is believed to be caused by the deepening and channelization of these rivers. Additionally, large increases in suspended sediment concentrations induced by flood dominance are thought to have decreased the effective hydraulic drag, enhancing further...

Hazar Port is located in Turkmenistan on Cheleken Peninsula, which is situated on the eastern coast of the Caspian Sea. Dragon Oil, an international oil and gas exploration company, is engaged in exploration and exploitation of oil and gas in the Caspian Sea. Dragon Oil would like to use the harbour of Hazar as supply base for the expanding of...

Turbidity currents are major transport agents in reservoirs in which high concentrations of fine sediments flow in. Reservoir sedimentation due to turbidity currents is often severe in these cases. Turbidity currents are not well understood due to their complex turbulent flow structure, the interaction between the flow with the particles and the...

An offshore terminal is proposed to be constructed adjacent to the entrance of an Estuary in the Niger Delta. A dredged approach channel of around 10 km long, 250 m wide and to a depth of -14 m LAT is required to allow ships to reach the terminal. From earlier research it is found that high transport rates of fine sediment, in the order of 10...

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...

Dredging and reclamation works are known to generate significant amounts of turbidity. In most coastal zones around the world, the resulting clouds of suspended fine sediment bring along environmental risks. Dredging contractors take mitigating measures to prevent free spreading of turbidity, which is usually also demanded by their clients and...

The objective of this project is to assess the influence of suspended sediment on hydrodynamic properties in the study area from tidal damping aspect. Firstly, through conducting tidal amplification factor analysis based on real time measured data, seasonal variation in sloping tendency has been observed. The difference in sloping tendency...

Light is attenuated by materials present in the water column by scattering and absorption. The knowledge of light attenuation and its contributing factors influencing visibility/turbidity is unknown in Singapore waters.

Lake Markermeer is a large and shallow freshwater lake in the center of the Netherlands. The lake was originally part of the Zuiderzee, a sea inlet of the North Sea. The lake is an important ecosystem, especially for water birds. The main problem in Lake Markermeer is the decreasing ecological value. High turbidity levels are believed to be one...
