ARRESTING MAXIMUM AMOUNT OF RAINFALL AT THE SITE OF OCCURRENCE

• Mechanical practices like levelling, bunding, terracing, contour furrowing, trenching, ridging, etc. help arrest the rainfall at the site of occurrence and provides more time to the rain water to soak into the soil.
• Levelling and grading
  • It is the process of the reshaping land surface to a planned grade which usually requires cutting of high areas and filling of low sports to remove surface irregularities and unevenness.
  • It reduces erosion, controls water flow and improves surface drainage.
• Contour bunding
  • Contour bunds are constructed to intercept the run-off. Contour bunds are usually less than one metre in height.
  • They are followed in low to medium rainfall area and relatively permeable soils.
  • In areas having rainfall more than 500 mm graded bunds are preferred to remove the excess water.
• Bench terracing
  • These are followed in areas of steep slopes (10-30%).
