The hydraulic and filtration properties of geosynthetics allows them to be used highly effectively in place of traditional filter layers. Typically, a single layer of geotextile fabric can replace a succession of stone filter layers.

Climate change is one of the primary causes of progressive erosion problems on a global scale. Natural vegetation can provide a certain level of erosion protection, it is often inadequate on steep slopes or areas prone to wave run-up or intermittent high velocity flows. This can occur in coastal areas, rivers, lakes, reservoirs, drainage ditches, flood bunds and overspill ponds.

River and canal banks are subject to wave action creating reverse flow conditions, it is this dynamic erosive force that undermines bank stability and affects channel flow and navigability.
