Rainwater Harvesting Studies Across The World and Türkye

and domestic use, and compare global rainwater harvesting studies with those
conducted in Turkey. In the conclusion and recommendations section, future
actions needed for rainwater harvesting are discussed, and suggestions are made.

1.1. Technical Details of Creating Micro-catchment

In micro-catchment water harvesting method, water is harvested through
structures of various height and depth constructed on soil surface as shown
in Figure 1. Based on their shapes, these structures are named as inter-row
water harvesting, terraces, semi-circles and triangular strips, pocket terraces,
vallerani, pits, meskat type harvesting, and contour ridges. The ratio of surface
runoff area to planting area varies between 1:1 and 10:1.
The type of the plants planted during the formation of micro-catchment basins
plays an important role in its success because the surface runoff water reaches not
only the area it flows through, but also the cultivation area. For this reason, the
runoff water is directly accumulated around the roots of the plants, which supports
plant growth. From a technical standpoint, micro-catchment water harvesting can
be evaluated under four main headings: suitability, feasibility, limiting factors, and
the examination of micro-catchment size. The micro-catchment water harvesting
method has been regarded as a suitable water collection technique for regions
with an average annual rainfall of 250 mm (Boers et al., 1986).
