Erosion of sediment through cellular revetment blocks applied as slope protection along coasts and inland waterways

Erosion of banks and dikes subjected to water motion can be prevented, for instance by application of cellular concrete revetment blocks. This type of revetment combined the merits of a closed block revetment and a slope revetment consisting of loose materials. Advantages are high permeability, high stability against wave attack and low block...

The permeability of closely placed blocks on gravel

The permeability of a layer of closely placed concrete blocks on a sublayer of gravel or sand without a geotextile has been investigated. The results indicate that the permeability of the blocks can be described as a combination of the permeability of the joints and the permeability of the the gravel just below the blocks. The permeability of...
