Erosion control

Why erosion control

• during the erosion process soil particles are transported, resulting in the gradual deformation and destruction of slopes, banks, shores, rivers bottoms, etc.
• elsewhere, erosion causes undesirable sedimentation on agricultural land and roads, in rivers and drainage systems, etc.

How can we control erosion?

a)Existing slopes:

• prevent removal of the vegetation
• in case of new slopes protect the fertile surface layer by means of:
  -coarse, less erodible surface
  -flatter slopes / terraces
  -surface cover with concrete, stones, plastic sheets
  -temporary plastic sheets over surface in rain season
  -geosynthetic mats
  -biodegradable mats

b)In case of slopes of ditches/channels:

• revetment structure
• concrete blocks
