The Dead Sea, the Arava and the Southern Negev are hyper-arid desert areas in which the average multi-year precipitation is less than 50 mm. There is great spatial-temporal variation of rainstorms. The origin of most rain events is the Red Sea trough; events are usually accompanied by thunder and lightning storms. Rain intensities are high and most of the rainfall is local. The rainstorms cause flash-flooding of streams. A high percentage of the flood waters infiltrate the surface and become subsurface groundwater. This groundwater, as well as ancient groundwater aquifers enable settlement in the area.
Research in the Dead Sea and Arava include monitoring each of the rain events, and monitoring of floods and the infiltration of floodwater to the groundwater aquifers. Alongside monitoring and research activities, we prepared a curriculum for schools that educates youth about water in the desert.
