Coastal rock structures are widely used in coastal engineering for a variety o f purposes, includiag controlling the morphological development of beaches and providing protection against coastal erosion or flooding by wave overtopping. Strict adherence to existing design guidance has resulted in many of these structures being built using...

Er is een analyse van de waarnemingen en metingen met betrekking tot ontgronding uitgevoerd voor de 1:1 modelproef in 1992 in de Deltagoot met golven van Hs 0.75 m tot 1.35 m op een grastalud van een dijk. De gemeten ontgronding is veel geringer dan tijdens vergelijkbare proeven op klei met een bodemstructuur, maar zonder zodelaag. Pas na vele...

Deze notitie beschrijft de resultaten van een inleidend onderzoek naar de mechanismen van de erosie van de basislaag onder geometrisch open filters. Hierbij wordt in eerste instantie uitgegaan van de beter onderzochte erosie van de bodem van een waterloop zonder beschermende filterlaag. Op basis van metingen van Van Os (1998) in een inleidend...

The second Chapter refers to the institutional and legislative framework, that is, the laws in force at the different levels, from local to global, in each partner’s country and concludes with considerations on optimal levels of coordination. Chapter III begins with the methodology recommended for the study of small-medium basins, based upon the...

When bank protection works are constructed along an eroding outer bank, it is often observed that the bed along the outer bank becomes substantially deeper, sometimes causing the failure of the bank protection works themselves. Despite our awareness of this deepening phenomenon, its causes and quantitative estimation is still a matter of...

Het doel van het handboek ontgrondingen is een antwoord te geven op ontgrondingsvraagstukken zoals een ontwerper van waterbouwkundige constructies die tegenkomt. Verschillende deelstudies worden voor het afronden van dit handboek uitgevoerd. Het verifiëren van ontgrondingsformuies staat centraal in deze studies. Hier is de voorspellingskracht...

A research project was carried out at the Delft University of Technology in order to study the interaction between waves as weil as a current and a muddy bed. For this purpose several experiments were made on two artificial clays, namely China Clay and Westwald Clay. The results of the experiments on China Clay were reported by De Wit (1994). In...

Scour is a natural phenomenon caused by the flow of water in rivers and streams. Scour occurs naturally as part of the morphological changes of rivers and as result of structures man-made. Several types of scour can be distinghuished. Experience has shown that due to sand or flow slides or micro instabilities at the end of the bed protection,...

Scour is the lowering of the sea or river-bed as a result of non-equilibrium sediment transport conditions and can be divided into several categories (Breusers and Raudkivi, 1991). Local scour, which may occur at the base of a structure because of the affected flow pattern, can severely endanger the stability of this structure. Many varieties of...

Excessive local scour can progressively undermine the foundation of a structure. Because complete protection against scour is too expensive generally, the maximum scour-depth and the upstream slope of the scour hole have to be predicted to minimize the risk of failure. In 1961 a systematical research 'tY'ith respect to scour holes started in the...
