Detailed laboratory measurements of the wave and current field induced by bi-chromatic waves incident on an artificial surfing reef are presented. Strong wave focussing occurs on the surfing reef. Both PTV and in-situ measurements are reported that show the presence of a strong rip current flowing oblique off-shore. Observed water level set-up...

Wave surfing is existing and becoming more attractive in the Netherlands. However natural wave conditions are not suited to encourage the sport. To improve the surf conditions of the local waves, Artificial Surf Reefs are potential solutions. As a part of intentions to optimise the design of Artificial Surf Reefs, this thesis is aimed at gaining...

Wave surfing is a popular sport all around the world where the conditions allow for it. Waves preferred by surfers are higher than 1 meter, have a certain hollow breaker shape (plunger) and the angle under which a wave breaks, the peel angle, is within 30-70 degrees. Also in the Netherlands surfing becomes increasingly popular but Dutch wave...

For the calculation of bottom protection in harbours near quay-walls, analytical formulas are used. The current experiences suggest an overestimation of load on the harbour bottom. Extensive measurements in prototype situations are very expensive. For this reason, the use of a computer model will be far more economical. However, at this moment...

The floods of the River Rhine and the River Meuse in 1993 and 1995 pointed out the importance of river intervention works to maintain safety for surrounding inhabitants. To predict the consequences of such engineering measures on river morphology, numerical computer models are used. Due to the high socio-economic value of the Dutch river system...

This Masters Thesis is a pilot research project in order to investigate which parameters, other than the wave energy density spectrum, could play a role in breakwater damage on variable foreshore steepness. The research project is based up on laboratory research, were for equal wave spectra at the toe of a coastal structure significantly more...

Single layer armouring is a state-of-the-art protection for rubble mound breakwaters. The quality of placement affects interlocking of the armour units, which is essential for the hydraulic stability of the entire armour layer. The main objective of this study is to make a detailed design of an Xbloc placement, this includes grid design,...

The bed and bank of a river, enclosing structures and other works where water is involved are exposed to waves, currents and water level changes. Bed and bank protection works are necessary to prevent eroding of the bed, bank or structure. Bed and bank protection works, on fascine mattresses, geotextile or on a granular filter, are important...

Om het benedenstroomse gebied van de Mary River te Australite beschermen tegen verdere zoutindringing, zijn er door "Australian Marine and Offshore Group", een Australisch ingenieursbureau, verschillende oplossingen aangedragen die deze zoutindringing reduceren of zelfs compleet tegen gaan. Vervolgens zijn de gevolgen van de gekozen oplossingen...

Designing breakwaters on steep foreshores faces some problems. At present, it is not known what the influence of the steepness of the bottom slope is. Design formulae for armour layers don't take the bottom steepness into account in a direct manner. In theory, in irregular waves, wave average heights in shallow water become higher as the bottom...

Grote schepen worden steeds vaker uitgerust met grote boegschroeven om beter te kunnen manoeuvreren in havens. Wanneer een schip wegvaart wordt de boegschroef gebruikt om met de voorkant van het schip van de kade weg te draaien. De straal van de boegschroef uit een tunnelbuis wekt een turbulente stroming op die loodrecht tegen een verticale...

Artificial Surf Reefs (ASR) are built to improve the surf conditions of the waves. Three ASR have been realized over the last decade and many more are planned to be constructed within a period of ten years. Even though a hot topic, ASR design is often done fairly ad hoc and there remains great uncertainty as to what the optimal dimensions of the...
