Combined wave-current flow is defined as flow in which waves and currents are present together. One of its occurrences in nature is at a tidal inlet system, where incoming waves meet either a current in the same (following) or opposite (opposing) direction. This type of flow is different when compared to wave- or current-only flows. As a result,...

Gas extraction has caused increased seismic activity in the area of Groningen, bringing about considerable damage to houses. The houses are generally old masonry houses with flexible timber diaphragms. It is of importance to assess the response of these houses in order to apply proper retrofit measures. There has been substantial research on...

Fibre reinforced polymer (FRP) is a new construction material that often is used for pedestrian bridges. It offers a good strength-weight relation, a long-term durability and slender bridge shapes. Slenderness has effect on dynamic behaviour of the construction and vibrations are common for these bridges. Hand calculations are commonly used for...

In this additional thesis a 2D urban flood model in the downtown area of Shanghai was investigated. Therefore a numerical model of Delft3D flexible mesh (DFM) was used. Since the model was investigated from scratch, a lot of data analysis and pre-processing was required to have reasonable input data. As input data a surface elevation map, a map...

The C2,1 and S2,1 spherical harmonic coefficients of glacial isostatic adjustment (GIA) models are dominated by true polar wander (TPW), the secular drift of the position of the Earth’s rotational axis with respect to the Earth’s surface. The Earth’s rotational state and its interior are closely linked. The deformation of the body induced by a...

In the last two decades, the global economy and population have been growing steadily. Due to these global trends the demand for dredging, trenching and deep sea mining activities have grown dramatically. In these engineering practices, underwater excavation is one of the major procedures which involves complicated physics. In dredging,...

In this thesis the equilibrium cross-sectional areas of a tidal inlet are investigated. The most common used methods to study cross-sectional stability are the Escoffier method (Escoffier, 1940) and the Modified Escoffier method (Van de Kreeke, 2004). The Escoffier methods are mainly empirical and lack physical justification. Therefore, in this...

EX-CORE, a novel foam core material developed by Donkervoort Automobielen B.V., allows the creation of complexly shaped sandwich structures in a one-shot out-of-autoclave manufacturing process. Products with small tolerances and high surface quality on all surfaces can be obtained. The EX-CORE technology has achieved its intended goal at...

The Particle Finite Element Method is a numerical tool that has been introduced more than a decade ago for the solution of engineering problems involving large deformations.
The method falls under the category of mesh-based particle methods, meaning that all information is stored on moving particles that represent the domain under analysis...

A single point mooring (SPM) system is one of the possible mooring systems in the field of Arctic floating production. It consists of a moored buoy to provide its anchoring unit with the capacity of mooring and ice sheltering. In the preliminary design phase, the performance of the mooring buoy must be assessed. This can be done by numerical...

Offshore wind farms are rapidly developing in Western Europe as an alternative means of clean energy. The foundation of wind-turbines in the shallow water of the Northern Sea is almost exclusively (over 87%) performed by short rigid monopiles, as an efficient and relatively cheap solution. Scour formation, meaning the soil removal around the...

Over the last decades, the People’s Republic of China experience large economic development, which have led to severe shortages of usable land. To counteract this, the Chinese central government promoted the development of coastal provinces by reclaiming large sections of coastal zones. One of these regions is Nantong Binhai Park or Tongzhou Bay...

Scarcity of (green) energy resources drives mankind further offshore and towards deeper waters. Protection of subsea infrastructure is of eminent importance in these environments. The key parameter to have a good control over the installation of rock is the falling time. For larger water depths up to 1200 meters, the accuracy of the falling time...

In the past decades, several EOR (Enhanced Oil Recovery) techniques have been developed to increase the amount of oil recoverable from a reservoir. Among these techniques, polymer flooding consists in the injection of a solution of water and polymer into the reservoir, and it is performed in order to lower the mobility of injected water. A...

A growing risk of flooding in coastal areas and the corresponding development of legislation drive continuous development in the field of hydraulic engineering. Failure due to
wave overtopping is not fully understood from a physical point of view. Existing knowledge gaps, processes that are not yet explained by physics or not even discovered...

A specific type of wave is identified as an infragravity wave (IG wave). These waves with very long wave periods, even up to minutes, are possibly dangerous for flood events, increased storm surge and/or failure of coastal defences. Current guidelines for dike safety are often determined for gravity wave dominated systems, so identifying IG...

Offshore wind energy is a fast-growing sector and it is quickly increasing its share in the European electricity mix. However, the costs are still high and the economic feasibility of offshore wind turbines is limited to shallow waters. This limitation plays a relevant role in the development of the sector and limits the offshore wind...

The growth of the offshore wind industry results in intensive usage of the sandy seabed in the North Sea, currently and in the coming decades. Large-scale bed forms are present in shallow seas with sandy beds such as the North Sea. The most dynamic bed forms are sand waves. Due to their dynamic behaviour, sand waves can interact within offshore...

The unreinforced masonry construction of Dutch terraced houses in Groningen is prone to lateral earthquake loading. To analyse the capacity of these houses, the faculty of Civil Engineering at the TU Delft started a test campaign. In this thesis, the experimental results served as benchmarks to validate a relatively new numerical method:...

Bed roughness is an important parameter for the prediction of sediment transport as well as calculating flow conditions near the bed. Numerical models are extensively used to make these predictions. In these models it is fundamental to have proper values for bed roughness. The bed roughness is being estimated using a dataset from an ongoing...
