The Ayeyarwady River is a river with large hydrological variations and an abundance of relatively fine non-cohesive sediment, causing the dynamic behaviour of the river with fast shifting channels. This dynamic behaviour, together with the large hydrological variations, is the source of a frequently flooding river with a moderate navigability....

Morphodynamic models are widespread in coastal engineering practice and indispensable to predict the effectiveness of (large-scale) sandy interventions. These models enable quantification of the effects on enhanced safety against flooding and on environmental impact over time, based on physical processes such as hydrodynamics and sediment...

The Rhine ROFI ( region of freshwater influence) is a dynamic area where various processes and timescales come together. Research has shown that stratification caused by the freshwater outflow of the Rhine alters the tidal currents in front of the Dutch coast. In the case of the Netherlands the tide behaves like a kelvin wave, which causes...

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 use of the detached offshore submerged breakwater (SBW) for coastal protection has an increasing popularity due to its low aesthetic impact on the natural environment. Submerged breakwaters however have only rarely been adopted and therefore its efficacy remains largely unknown (Ranasinghe et al. 2010). Shoreline erosion has been reported in...

A 2Dnumericalmodel is set-up for the tidal bore in the Sittaung River. This model is used to analyse the effect of the bottom friction, bathymetry, tidal range and river discharge on the propagation of the tidal bore. To obtain information about the tidal bore the Sittaung River is visited two times. During the second visit, depth measurements...

Bangladesh is characterised by its complex river system, which includes the downstream ends of two of the largest rivers in the world: the Ganges and Brahmaputra. Extremely variable flows and fast morphological changes are the principal characteristics of this system, which presents exceptional challenges for river engineering. Distributary...

Coastal zones are extensively used by humans for work, living and recreation. About three billion people live and work within a couple of hundred kilometers from a coastline. In addition the coast is an important breeding zone for marine species. This is also the case at Lake Bardawil. Lake Bardawil is a relatively large lake on the north-west...

The Oesterdam tidal flat nourishment is a hook-shaped nourishment that was constructed in November 2013 in the Kom area of the Eastern Scheldt. One of the objectives of the nourishment is to increase the design life of the Oesterdam in the face of increasing wave loads due to structural erosion of the intertidal flats. A study is conducted in...

Additional master thesis - To mitigate the effects of the hydropower dam development on the Mekong river system, research must be done on the effects of sediment catchment of these dams. With unknown amounts of sediment, stored in the banks and in local bars, all spread over this long bedrock channel, local sediment transports are hard to...

The Sand Motor is a unique and dynamic solution for coastal erosion, aimed at distributing the nourished sand along the Delfland coast. Besides enhancing coastal protection, the Sand Motor has been designed to also provide opportunities for recreation and nature development. The contributions of ecosystems to human well-being, that arise from...

Large sedimentation is observed in the Yangon port area in Myanmar and this sediment is blocking the entrance channel into the port. The entrance channel is dredged intensively to keep it navigable but insight into the sedimentation processes is limited. The sedimented area rises above the water level in dry season and is known as the Inner Bar....

In this report a study is carried out on the Magdalena River near the village of San Pablo, Colombia. The Magdalena River near San Pablo experiences two major issues which are related to navigation and erosion. The major problem for inland navigation is the sharp bend of the Magdalena River at San Pablo, which has too small a radius, causing...

Mixing systems are used in deep lakes to prevent blue algae from rapidly growing. Air bubbles rise from the bed, dragging water from below upwards. The resulting vertical circulation suppresses blue algae growth. However, these systems demand electricity of about €25,000 per km2 per year. The airlift promises to mix the water more efficiently,...

The overall behaviour of the tide-dominated Western Scheldt is in general well known. Its multichannel-system consists of ebb and flood channels, separated by intertidal areas; the tidal flats. The estuary shows a dynamic behaviour of erosion and sedimentation of the tidal flats. A large flow slide occurred at the tidal flat of Walsoorden in...

The tide-dominated Scheldt estuary is located in the southwest of the Netherlands. From the Dutch-Belgian border seawards, it consists of a system of channels and shoals and an ebb-tidal delta facing the North Sea. The behaviour of non-cohesive (sand) and cohesive (mud) sediment particles in the area are (until now) generally studied using...

The current report aims to understand the hydro- and morphodynamic response of the Western Scheldt in a large sediment dumping operation. This study investigates the estuary’s response to sediment dumping in the Everingen channel area, which is located in the middle of the Scheldt Estuary, The Netherlands. Furthermore, it studies whether these...

The Sand Motor is a mega-nourishment characterized by a very large sand volume of around 20 million m3 placed along the Dutch coast. The Sand Motor is a pilot project to evaluate the performance of an alternative nourishment strategy with respect to different functions of the coastal system. Within the scope of the coastal functions, the hook...

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...

The response of longshore sediment transport to the morphodynamic state of the beach was assessed with the use of the process based numerical model, Delft 3D. For this purpose, idealized simulation bathymetries that reflect morphological characteristics of two different beach states (namely longshore bar and trough and transverse bar and rip)...
