Groundwater recharge also encompasses water moving away from the water table farther into the saturated zone. [1] Recharge occurs both naturally (through the water cycle) and through anthropogenic processes (i.e., "artificial groundwater recharge"), where rainwater and/or reclaimed water is routed to the subsurface.
The major river in Ethiopia is the Blue Nile. However, most drinking water in Ethiopia comes from ground water, not rivers. Ethiopia has 12 river basins with an annual runoff volume of 122 billion m 3 of water and an estimated 2.6–6.5 billion m 3 of ground water potential.
Groundwater recharge varies between values exceeding 350 millimetres (14 in) per year in the upper highlands and no recharge at the bottom of the rift valley. [ 10 ] [ 13 ] Groundwater is predominantly recharged at the escarpments and highlands above 1,900 m a.s.l., [ 14 ] where annual rainfall is higher than 1,000 millimetres (39 in). [ 13 ]
EthioTrees not only improves soil organic carbon, biomass, groundwater recharge, or biodiversity but also cash income for landless farmers.Most farmers estimate that lack of access to water is the main problem for their livelihood.

Water located beneath the ground surface An illustration showing groundwater in aquifers (in blue) (1, 5 and 6) below the water table (4), and three different wells (7, 8 and 9) dug to reach it. Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in ...
Direct recharge is storing water by allowing it to percolate directly to storage in the groundwater basin. [1] With direct recharge it floods an area so that water seeps through the ground to get to the aquifers. [3] The water is then pumped out when there is more of a demand with the use of recovery wells. [3]
[13] [14] Groundwater storage is affected by diffuse groundwater recharge through the soil and by point recharge from surface water bodies. [10] Diffuse groundwater recharge is modeled as a function of total runoff, relief, soil texture, hydrogeology and the existence of permafrost or glaciers. [ 7 ]
