Filtration

Hydraulic structures such as reservoirs, dams, riverbanks, and coastlines are subject to severe hydrodynamic stresses. They therefore need to be stabilised by appropriate protection systems. These systems comprise two different part.

The outer part must absorb the hydraulic energy of the waves. Rip-rap blocks, prefabricated concrete elements or gabion mattresses are typically used for this purpose. The function of the inner part is to prevent the soil from being eroded. This function is referred to as filtration. Several layers af granular material with well designed grain size and thickness have been widely used for this purpose. However, to be effective, granular filters need to be matched to the opening size of the revetment and the grain size of the subsoil. As a result, the granular filters often require numerous layers of different sized gravels. Thus, construction of granular filters is usually expensive, time consuming, and difficult to control.

The development of geotextile filters has revolutionised hydraulic filter design and construction. Geotextiles can be used as a substitute for conventional aggregate filters and provide a direct transition between the revetment and the subsoil. The use of a suitable geotextile as filter has the following advantages over conventional granular filter system because:

  • It reduces the number and thickness of granular filter layers and hence the cost
  • It provides uniform hydraulic and filtration characteristics
  • It is easy to install and control at site
