Study Notes
Water Harvesting Techniques
- Techniques categorized into four groups: micro-catchments, macro-catchments, floodwater harvesting, and storage.
Contour Bunds (Ridges)
- A technique used primarily for tree planting and water harvesting.
- Optimal for rainfall conditions ranging from 200–750 mm.
- Main advantage includes cultivation of crops or fodder between the bunds, maximizing land use.
- Semi-circular bunds suited for growing trees and shrubs only.
- Recommended spacing of 10 m between two bunds on slopes up to 0.5%.
Micro-Catchments
- Types include Negarim, Natural depressions, and Meskat.
- Each tree requires a micro-catchment size of approximately 50–100 m².
Bunds and Pit Dimensions
- The junction of the bund and cross-tie should have a recommended pit depth of 50 cm.
- Contour ridges for crop production are limited to areas with higher rainfall conditions.
