Pubben, S.G.T. (author)
Estuaries are complex systems that show a variety of hydrodynamic conditions. These conditions are influenced by bathymetry, geometry, climate characteristics, interacting fresh and salt water flows, and mixing effects caused by winds and wind-waves. The interaction between fresh and salt water flows in combination with mixing effects caused by...

Ton, A.M. (author)
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...

Double Master of Science in Hydraulic Engineering (Civil Engineering and Geosciences) and Applied Mathematics (Electrical Engineering, Mathematics and Computer Science) - It is of importance to know how the water is behaving in rivers due to the dangers, such as flooding and eroding of land, it can bring with it. Present day we are still...

The decommissioning market expenditure is expected to grow further in the years to come due to increasing number of platforms that near the end of their production cycle, mainly being xed steel structures (<4,000 [Te]) positioned in shallow waters (30 to 75 [m]). The risks of such operation emerged the need for semi-submersible, heavy-lift...

In this thesis, a method was developed, with which the infragravity waves and morphological changes of a sandy foreshore are included in the calculation of the probability of dike failure due to wave overtopping. Constructing a natural foreshore in front of the dike can be an attractive and innovative method to decrease the failure probability....

In electrolyte solutions, an electric potential difference, called the Ionic Vibration Potential (IVP), related to the ionic vibration intensity, is generated by the application of an acoustic wave. Several theories based on a mechanical framework have been proposed over the years to predict the IVP for high ionic strengths, in the case where...

Aquatic vegetation, found in coastal waters and inter tidal areas, has important features for hydraulic engineering solutions, including sedimentation and stabilization of the bed. The increasing demand to predict wave hydrodynamics with aquatic vegetation asks for insight in the mechanisms and improved model methods. Striving to a more...

Measurements of nearshore currents can be performed using a range of existing measurement techniques. Although every technique has its specific benefits, capturing strong spatial gradients in a flow field with sufficiently high spatial resolution often proves to be difficult due to high costs or practical difficulties associated with these...

Controlling the distribution of water and sediment at river bifurcations is one of the main challenges in river engineering and management. This distribution affects the stability of river bifurcations as well as the distribution of flooding risk, navigability and environmental conditions. The governing factors are the hydrodynamics of the two...

The use of natural user interfaces instead of conventional ones has become a reality with the emergence of 3D motion sensing technologies. However, some problems are still unsolved (for example, no haptic or tactile feedback); so this technology requires careful evaluation before the users can benefit from it. We argue, that the best benefits...

Coral reefs are highly valuable ecosystems, which are under an increasing number of environmental pressures. Sedimentation and sediment transport patterns are among key physical drivers of coral reefs, so it is important to improve our understanding of these poorly studied dynamics on reefs. To this purpose, flume experiments were performed on a...

Three-dimensional hydrodynamic z-layer models, which are used for simulating the flow in rivers, estuaries, and oceans, suffer from an inaccurate and often discontinuous bottom shear stress representation, due to the staircase bottom. We analyze the governing equations and clearly show the cause of the inaccuracies. Based on the analysis, we...

Coral reefs are highly valuable structures in many respects and it is increasingly important to understand hydrodynamics and morphodynamics around reefs to be able to better protect them and their hinterland. Flume experiments were performed on a scaled fringing reef in the laboratory facilities of Deltares in Delft. The objective of this thesis...

Introduction: The addition of vegetation to the banks urban drainage channels is an increasingly common measure for improving water quality, enhancing ecological health, and improving aesthetic appeal. An in-stream wetland concept is proposed for channels in Singapore to just that, but faces a major challenge in that high flow rates during storm...

Problem definition The city Mar del Plata has one of Argentina's largest ports and biggest seaside beach resort. After the construction of the port, a steadily growing sandbank appeared in the port entrance and considerable erosion occurred on the northern beaches. To warrant the accessibility of the port, frequent maintenance dredging is needed...

Aquatic plants –or macrophytes- are an important part of coastal, estuarine and freshwater ecosystems worldwide, both from an ecological and an engineering viewpoint. Their meadows provide a wide range of ecosystem services: forming a physical protection of the shoreline, enhancing water quality and harbouring many other organisms. Unfortunately...

Objective Due the coastal protection program along the Dutch coast, the groins that first defended the coast against erosion, are now covered under sediment. Due to erosion the covered groins will resurface however. The objective of this study is to investigate the effect of the resurfacing groins on the hydrodynamics and sediment transport....
