How can we control erosion?

In nature it often takes thousands of years till erosion has stopped and a gradual building up of a natural, vegetal cover has taken place.
Mankind can make artificial protection with concrete, stone, wood, etc. or help nature to establish a natural cover.

Also it is possible to use prefabricated plastic erosion control products. Three-dimensional erosion control mattings, made of polyamide monofilaments welded together where they cross, with an open space of over 95%.
