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...

The interaction between soil, water and bed or slope protection

The interaction between soil, water and structure is discussed for a bed and slope protection. It is shown that for various types of structures, and various boundary conditions, this interaction can be approached in a uniform way . The hydraulic conditions at the boundaries of the structure and along the non-protected parts of the bed result in...
