In the Southern Bight of the North Sea, a Coastal Turbidity Maximum (CTM) can be observed in the Belgian coastal area around the port of Zeebrugge. Understanding the dynamics of this turbidity maximum is of great importance in coastal zone management. Our research studies the CTM with a numerical process model

Over the past centuries natural river banks have been transformed into banks with artificial revetments or sheet piles to protect them from erosion. Important river features for flora and fauna have disappeared and the ecological quality of the river reduced dramatically. Recently, the importance of the ecological function of rivers has been...

We experimentally tested the effect of a  largerange in helical flow intensity and  sedimentmobility on equilibrium transverse  slopes,which resulted in a function for slope  effectsdepending on bed state and  sedimenttransport mode, that deviates from  linearfunctions with sediment mobility in  literature...

The objective of this study is to get a new insight into in-situ characterization of fluid mud layers. Water Injection Dredging has been performed to create a fluid mud layer in the 8th Petroleumhaven at the Port of Rotterdam. Four measuring tools, conventional multi-beam echo-sounder, DensX, Graviprobe and Rheocable have been used to monitor...

Purpose: This paper advances the concept of meta-Corporate Real Estate Management (metaCREM) as an adjunct to existing knowledge work in the field. It argues for its existence and relevance, and suggests a number of areas where research with such a focus could occur to advance knowledge in the field.
Method: The method is what might be...

Confluences are fascinating elements in river systems. The merging of tributary rivers produces complex hydrodynamics that can play an important role in sediment transport problems, ecological studies or the routing of a pollutant. If the two merging rivers originate from different regions they can have different characteristics. One such a...

Any endeavour to accurately model flow through fractured porous media at the field-scale must overcome two important challenges. First, the discretized representation of the medium needs to accommodate the complex geometry of intersecting small-scale fractures with various lengths, apertures and orientations. Second, the model formulation must...

Research into the Vertical Axis Wind Turbine (VAWT) has been progressing over the last few years due to
the large shift in design constraints for large floating offshore wind turbines by leveraging tools and experience
from research beginning in the 1970s and lasting until the HAWT established market dominance in the 1990s. The beginning...

Although many studies regarding bank erosion  and accretion can be found in the literature, it is  not common to find works studying the interaction  between opposite banks. Some existing  morphodynamic models describe bank erosion as  an event that depends on near-bank flow and bed  topography, as well as on...

An horizontal axis wind turbine placed in a free stream develops a wake behind its rotor. Inside this wake, complex vortical instabilities are developing and can lead to turbulent structures generation1 . In order to predict performances and loads of wind turbines in wind farms, it is essential to accurately characterize these wakes and their...

The mechanisms leading to the formation and maintenance of a Coastal Turbidity Maximum (CTM) along the Belgian coastline was investigated using a complex 3D numerical model. Interpretation of model results suggests that the sediment concentration in this CTM may have strongly increased as a result of human interventions in the 1980’s. The large...

Since Freeman (1984) stakeholders are an established concept in management sciences and practices. This is not different in the field of corporate real estate management, where stakeholder analysis and administration became an essential tool for strategy design and execution. Delft scholars traditionally divide corporate real estate stakeholders...

During recent decades, mangrove forests have experienced severe degradation due to unsustainable land use. Restoration of mangrove ecosystems requires the recovery of their habitat, considering ecology, hydrology, hydrodynamics, and sediment transport. In a first pilot in 2013, brushwood dams were built on the eroding coast of Demak, Indonesia,...

Recently, engineers propose longitudinal  training walls to replace traditional transverse  groynes. This new intervention is expected to  maintain a navigation route under low flow  conditions while not hampering flow  conveyance of the river channel. Navigation  occurs mainly in low-land river channels where ...

The drivetrain of most wind turbines currently being deployed commercially consists of a rotor-gearboxgenerator configuration in the nacelle. This abstract introduces the control system design and optimization for a wind turbine with a hydraulic drivetrain, based on the Delft Offshore Turbine (DOT) concept1 . This concept enables the connection...

The presented research evaluates the concept of providing an airport’s Air Traffic Control with a bird strike advisory system. Such a system informs the controller about current and predicted bird movements in the arrival and departure corridors. Based on this information, the controller can decide to delay or reroute air traffic in order to...

For wind farm control, the current practice in industry is that every turbine has its own wind turbine controller that will optimize its own performance in terms of power output, load mitigation, and/or reference tracking. However, in several national American and European1 research projects, researchers from industry and academia have shown...

In view of the anticipated climate change, many countries face increasing risks of flooding. In many countries, flood protection measures will need to be taken in the coming years to protect flood prone areas from the increased risk of flooding. Since the end of the 20th century, the traditional hard flood protection measures are increasingly...
