Mining activities in a coastal zone: Effects and remedial measures in the Netherlands

In July, 1959, the presence of gas in the subsoil of the Province of Groningen in the extreme NE part of the Netherlands was confirmed. Subsequently, it became clear that the mining of the gas would result in considerable subsidence and a disruption of the drainage system of an area adjacent to the North Sea, and situated already partly below...

Influence of the density of placement on the stability of armour layers on breakwaters

Studies on the stability of the amour layer (d’Angremond et. al. [1999] revealed the importance of density of placement. The current research focuses on the influence of the density of placement on the stability of cubes in a double armour layer and tetrapods and rocks in a single armour layer. The experiments were performed in the Laboratory of...

Positioning of cubes on a breakwater slope

Recent research has shown that it is possible to use concrete cubes as a single armour layer on breakwaters. However, this is only possible in case a placing density of at least 70 % is achieved. In lab-tests it is no problem to place cubes with this density, however it is questionable if such a placing density can be achieved in prototype...

Comparison construction costs conventional rubblemound breakwaters/bermbreakwater

Given a harbour location and a wave-climate, two different types of rubble-mound breakwaters were designed. Using realistic quarry yield curves and prices for production, transport and constmction, the total costs of the conventional statically stable and dynamically stable bermbreakwater designs were compared to each other. This comparison led...
