Tabia
Similar to the Jessour technology, Tabias comprise an earthen dyke that captures runoff, increasing infiltration and reducing erosion. Different from Jessour, Tabias have a lateral bund that directs excess runoff water along the dyke. Besides, Tabias sometimes have a small floodwater diversion dyke (image) that directs extra water from a (ephemeral) river or runoff path towards the Tabias, enlarging the catchment size. Trees especially grow well along the spillway lateral to the Tabia, since water infiltrates well there.
The ratio between the area where water is applied (production area) and the total area from which water is collected (catchment area) varies from 1:6 to 1:20.
