The contribution of different pathways of recharge to the groundwater in the Negev desert, the southern arid part of Israel, is examined by means of isotope and chemical signatures which are imprinted on the waters. All data lead to the conclusion that in arid regions the total quantity of water in local basins is limited. However, base-level basins, such as inter-mountain basins, rift valleys, etc, form a sink into which relatively small quantities from local watersheds flow which may accumulate to substantial quantities that could be used for regional development projects. The Arava rift valley is discussed as a case study.-from Authors
