Soil erosion has, and will always be a big
problem in South Africa. To help combat this problem the Institute has designed
and constructed silt fences consisting of low cost materials.
Some 20 different drop inlet and weir type structures has been erected by
making use of different and easily obtainable materials. The test on these
structures produced outstanding results.
By making use of these methods, the further erosion in small and medium size
dongas can be halted and silt deposits created for vegetation.
