The design formula for rubble mound breakwaters by Van der Meer has an unclear Notional Permeability term. This term causes a lot of confusion for designers. In the past many people have tried to derive a better formulation for that term by experimental and analytical research. The goal of this study was to obtain a better formulation along a...

In this research, the influence of internal syn-sedimentary structures on the pattern of deposition and distributions of deltaic clastic reservoir deposits in the Tomboy Field Area, offshore Nigeria is investigated using seismic modeling attributes (deposit thickness, root mean square (RMS) and maximum amplitude, structural contours, time slices...

During this user centered design project for Wacom Europe GmbH a new accessory for the Interactive White Board (IWB) was designed. This product for the educational market combines pressure sensitive reflective LCD technology with Wacom’s pen technology. Right at the start of this project users have been introduced to these technologies. They...

Diffraction diagrams are frequently utilized by engineers within the feasibility and early design phases of a project. These helpful graphics, based on directional spreading and wavelength, can be used for a number of layouts and angles of incidence. In spite of the tendency to design breakwaters for the fullest dissipation of wave energy,...

In a consortium Iv-Infra has made a proposal for a storm surge barrier to protect the city of New Orleans against hurricanes like Katrina. The design is a pile supported concrete structure with a considerable complex superstructure. The superstructure of the reference design consists of a perforated inclined wall and a vertical back wall. Since...

A new and innovative idea to reduce the wave reflection in front of vertical walls is by means of dynamic breakwaters, which dissipate wave energy by using moving elements. These moving elements in combination with a spring and a 'dashpor' to dissipate energy reduce the wave reflection in a wide range offrequencies (see Figure 2-1, 2-2 for...

At the Laboratory of Acoustic Imaging and Sound Control, much research is done in the field of room acoustics. The impulse response is widely regarded as the most meaningful characteristic in room acoustics. For a certain combination of source and receiver position, the impulse response is the sound pressure at the receiver position as a...

Een teenconstructie van een golfbreker is het deel van een golfbreker dat zich aan de onderzijde van het golfbrekertalud bevindt. Een teenconstructie geeft steun aan het voortalud van de golfbreker en voorkomt, samen met andere golfbrekeronderdelen, het wegspoelen van constructiemateriaal en ondergrond vanonder een golfbreker. Bij het...

To predict the effect of a floating viscoelastic slab on the propagation and attenuation of gravity waves, a theoretical linear model has been developed. The slab has been modeled as a Kelvin-Voigt model and the fluid is assumed to be ideal. For long and short wave theory a dispersion relation for gravity waves covered by a viscoelastic slab of...

A wave entering a harbor will be diffracted and reflected, depending on the shape and the construction of breakwaters, quays and other objects in the harbor. The incoming wave can increase or decrease in height and a resonance can occur. This affects the manouvering of ships and the movement of moored ships, which influences the loading and...
