Verbeek, Merel C. (author)
The flow between bridge piers and through storm surge barriers and barrages is an untapped and promising source of water energy. This energy can be harvested with tidal or hydro turbines. In 2015, five turbines with a total capacity of 1.2 MW were retrofit in a flow opening of the Eastern Scheldt storm surge barrier (the Netherlands). These...

Mangrove forests effectively function as natural flood defences, and their deforestation has exposed millions of people worldwide to coastal erosion and flooding. Since mangroves require a stable sedimentary environment, stopping coastal erosion is a necessary step for their restoration. Bamboo structures have thus been built to induce accretion...

The submerged floating tunnel (SFT), also called an Archimedes Bridge, is a new type of infrastructure for wide and deep sea-crossings, regarded as one of the alternatives to bored and immersed tunnels and bridges. It is afloat in water employing its buoyancy and a support system to balance its self-weight. However, no prototype SFT has yet been...

Excess sludge handling is as important as treating the wastewater in determining the operational performance and costs in modern municipal wastewater treatment plants (WWTPs). In practice, excess sludge handling is widely implemented using anaerobic digestion (AD), in which the organic matter inside the sludge is not only stabilised and partly...

Underwater slope failure is a common problem in the fields of geotechnical, dredging and hydraulic engineering, posing a major risk to submerged infrastructure and flood defences along coasts, rivers, and lakes. The term ‘flow slide’ refers to a specific, complex failure mechanism of underwater slopes, which occurs when a substantial amount of...

The Eastern Scheldt storm surge barrier is an icon of Dutch hydraulic engineering. Downstream of the barrier, large local erosion pits (scour holes) have formed adjacent to the applied bed protection after its construction. It was expected during the design phase that these would develop, but both the magnitude of the scour hole depth as well as...

Transverse exchange processes of mass and momentum in floodplain regions of channels are of primary importance regarding the sediment transport and riverbank stability. The presence of large horizontal coherent structures (LHCSs) at the interface of the floodplain and main channel regions may contribute up to 90% the amount of transverse...

The Rhine reach comprising the Niederrhein and the Upper Rhine Delta is characterized by a long history of engineering interventions. The area is densely populated and the Rhine, the main inland waterway in Europe, justifying the need for such measures. Interventions have had a strong impact on morphodynamic channel characteristics. We use bed...

1D hydraulic models are largely used to simulate the propagation of flood waves and for flood mapping along river systems. The most common approach to account for the hydraulic effects of vegetated floodplains consists of imposing higher roughness coefficients. However, the flow resistance of vegetation is governed by plant submergence, which is...

After the European Water Framework Directive, riverbanks in several countries had the protections removed to improve the water quality and the river ecosystem. Particularly, the Meuse River currently has several kilometres of freely eroding banks, which may have consequences for other river functions such as navigation and flood conveyance. The...

The co-occurrence of storm surge, high tides and heavy precipitation increases flood probability and potential consequences compared to each hazard separately in Delta cities. The Huangpu River (HP) is a tributary of the Yangtze River in China, which drains Tai Lake to the west of Shanghai city, and meanders through downtown Shanghai. During...

The nature of the Meuse River is more than any other major river in the Netherlands formed by the presence of weirs. These were constructed almost one century ago to enable transport of coal; nowadays, the boundary conditions have changed and will continue to change in the future. The weirs reach the end of their lifetime around 2030; during...

Groynes have been replaced by longitudinal training walls in an 11-km long pilot project to optimize training of the river Waal in the Netherlands. These train­ ing walls improve navigability, reduce flood levels, create a sheltered second channel with more favourable ecological conditions, and decrease the erosive action on the river bed that...

This thesis presents a numerical framework for simulating advection-dominated flows which reconciles the advantages of Eulerian mesh-based schemes with those of a Lagrangian particle-based discretization strategy. Particularly, the strategy proposed in this thesis inherits the diffusion-free properties as in Lagrangian particle-based advection,...

Le, T.B. (author)
Rivers have been trained for centuries by series of transverse groynes. This generally results in damages to their ecosystems as well as in undesirable longterm morphological developments. We analyze here the possibility to train rivers in a new way by subdividing their channel in parallel channels with specific functions with longitudinal...

Mangroves are an interesting species of vegetation, surviving and thriving at the interface of land and water, in the inter tidal brackish coastal waters between the mean sea level and mean high water. Mangroves are a highly productive and complex ecosystem, providing numerous services and goods to people and marine environment. Mangroves are...

Vargas Luna, A. (author)
There is rising awareness of the need to include the effects of vegetation in studies dealing with the morphological response of rivers. Vegetation growth on river banks and floodplains alters the river bed topography, reduces the bank erosion rates and enhances the development of new floodplains through river bank accretion. The role of...

Chen, X. (author)
Due to climate change, sea level rise, increasing frequency and intensity of storms, and growing population in low-lying coastal regions, the risk of flooding is expected to increase. Owing to these developments, maintenance and adaption of the existing coastal flood defence is often required. To meet this dilemma, the concept of multifunctional...

The main objective of this project is to develop new measuring techniques for providing detailed data on sediment sorting suitable for sand-gravel laboratory experiments. Such data will be of aid in obtaining new insights on sorting mechanisms and improving prediction capabilities of morphodynamic models. Two measuring techniques have been...
