The starting point of this thesis lies in the area on Groningen, Netherlands. More specifically, induced earthquake activity is observed in this area due to gas extraction activities, which reduce underground gas pressure. In combination with the location’s geomorphology, liquefaction can occur due to earthquake excitations. Furthermore, the...

Coastal regions are more and more affected by changes in water levels, storm patterns etc. owing to climate change. Nourishments and other human interventions constitute common practice in order to maintain and secure these areas. However, many aspects, especially the hydrodynamics, are not yet fully understood due to the complexity of the...

As countries around the world are in a race for clean energy, various renewable energy sources are harvested to meet the energy needs. In Western Europe, wind energy is the primary source of renewable energy. To meet the energy demand, higher capacity wind turbines are being installed in deeper waters. In deep waters, monopile foundations are...

The presence of Arsenic in the groundwater, and eventually in the drinking water is a serious problem in many of the Asian countries. Due to it high toxicity to its removal is very essential. There are many removal technologies for the removal of arsenic such as adsorption, coagulation-filtration, membrane filtration, ion exchange and...

Offshore wind has achieved many milestones considering this relatively new and emerging industry. Its huge advancement is mostly driven by lowering the overall project cost and renewable energy targets which are set by the EU. One of the potential cost savers can be found in the foundation structure design in which the monopiles are the most...

Rapid injectivity decline is frequently observed during injection in unconsolidated sand reservoirs. Field data suggests that hydraulic fracture processes are directly or indirectly related to this injectivity decline. Conventional fracture theories do not apply to unconsolidated sand since this material has little to no cohesion and tensile...

The Sand Engine was constructed in 2011 with the main goal to enhance the natural dune growth. It is the first mega nourishment in the world comprising of 21.5 Mm3 of sediment. There is a large difference between the predictions of the dune growth (25 ha in 20 years) and the actual measurements (1 ha in 4 years). Therefore a more...

The demand for offshore wind farm installation is increasing in recent years as the concern in using sustainable energy source is rising. One of the primary steps in constructing offshore wind farm is the pile installation which is a high-risk activity due to the expensive offshore installation vessels requirement. Any factor which can result in...

This thesis describes how the simple random walk particle model can be extended to account for sand deposition and suspension, and for particle interaction: clumping together and falling apart. The extended models are analyzed, and the corresponding partial differential equations are derived. These equations are compared to the currently used...

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...

A mega-feeder nourishment is a concentrated nourishment that disperses over time due to wind, waves, and tide, and as a result ‘feeds’ its adjacent coasts. During the design phase of a nourishment, performance indicators can enable an objective comparison of a mega-feeder nourishment to alternative nourishment strategies, In the case of an...

The coastal waters of Nigeria are a difficult environment to build structures to control the local morphology and hydrodynamic conditions to ones desire. This difficulty is a consequence of the persistent high-energy swell wave climate and Longshore Sediment Transport (LST) in the order of one million cubic metres per
year. Besides these...

Cyclic behaviour of soil has stimulated researchers for several decades to develop constitutive models that will be able make accurate predictions of soil behaviour and at the same time they will be simple to use. Constitutive models are considered to be more valid compared to empirical models, because they comprise by equations that have actual...

A time-dependent capacity increase has often been observed for driven displacement piles in sand. Long-term bearing capacity increase after dissipation of excess pore water pressure is referred to as set-up. Significant increases in axial capacity have been reported where the rate of set-up varied between 15 and 75% per log cycle of time.

In recent years, offshore wind is becoming an increasingly growing market in Europe. Many resources are allocated towards ensuring its sustainable progress while one of the biggest uncertainties encountered lays in the offshore wind turbine's (OWT) foundations. In Europe, monopiles are the most widely adopted solution to found such structures in...

The beach at Ngapali, Myanmar is eroding, resulting in a shoreline which moves landward. The coastline gets closer to the vegetation each year and during the monsoon season, at high tide, it reaches the palm trees completely. The assumption is that this is due to people shovelling truckloads of sand from the beach to use for construction, this...

The use of fibre reinforced composite polymeric materials for primary helicopter structures has been increasing over the last decades due to their attractive properties; high performance and lightweight inducing more fuel savings than their metallic counterparts. With respect to the joining methods; structural adhesive bonding is preferred when...

A very common observation is the episodic erosion of beaches during storms and the slow recovery (accretion) afterwards (Yates et al. 2009). Morphodynamic models parameterize physical processes in order to relate the fluid motions (hydrodynamics) to the bed level changes (morphodynamics) over a wide range of spatial and temporal scales. Despite...

Great Lakes Dredge & Dock (GLDD) is one of the biggest dredging companies in the USA which provides engineering services in dredging and land reclamation. GLDD came up with an idea to develop a working model that can estimate spillage when using a cutter suction dredger (CSD) for cutting soft material like sand. The main reason for this is...
