Abstract
AbstractA review of potential local fresh-water sources in the deserts for the use of livestock herds, herders' settlements, and extractive and other industrial enterprises. One of the most promising approaches is held to be the use of takyrs [clay pans] as catchment areas for ephemeral runoff of precipitation, which is then directed into natural aquifers or artificial underground storage cisterns. Another potential source of water is large perched ground-water lenses that could be tapped by paired wells to prevent the intrusion of salt water from below. Artesian waters in the desert which are far from areas of recharge are found to be largely saline.
