Shita Wadi - Israel

A small watershed that collects floods and run-off. The lowest place is home to a (relativity) dense Acacia savana. The slopes are completely bare. The wadi is covered with alluvium resting on a 6 m layer of red surface of late Pleistocene, which includes silt, clay and fine sand. Rainfall is 30 mm

Geology

The Wadi (Valley) is the first towards south from the highest point in the Arava, Notza ridge which is 250 MASL.
It flows west to east, although in the past (2.5 MYA) the direction of flow was east to west. It ends in Ka Saidin salt flat. There are sedementry rocks from the upper creteacous of Mashash and Menuha formations. The wadi is unique in having a layer from an early pleistocen called the "red unit".

Vegetation

Since this is a hyper-arid area the only vascullar

Soils

The wadi has a unique "red unit" that is fine grained, with carbonate from an early pleistocen. Teh red unit sits in the low areas of the wadi where soil moisture is highest. There is conglomorate with small pebbles and fine greain forming reg soil. There is a gypsum concentration in carbonate clusters. The aluvium is young creteacous.

Hydrology

The watershed is 24 square KM in a braided stream pattern. Its maximum width is 3 km, the top layer is young aluvium. Some of the streams are active and others are neglected (by water). The number of active streams depends on the power of the flood. Rainfall is around 30 mm per yea, but has been going down in the last few decades. between 1993-2009 flood frequency has dropped to almost half.
