1.2. Technical Details of Creating Macro-catchment

In this water harvesting method, the main principle is similar to that of micro-
catchment water harvesting. The existing water flow is collected on the soil surface
and the excess water is removed from the soil in a controlled manner. However,
in this method, there is a large basin apart from the cultivation and planting area.
The slope of the marcro-catchment area varies between 0% and 50%.
This method is usually applied in regions with annual precipitation amount
of 200-1500 mm (Studer & Liniger, 2013). Macro-cathment water harvesting
techniques include stone bunds, wide half-circle bunds, trapezoidal bunds,
and water diversion channels in slope areas (Figure 1).
