Abstract

Gully incision has been eroding the alluvial sediments and loess soils deposited and developed along the valleys in the arid and semiarid regions of Israel. This phenomenon is critical in the arid regions of the Negev Highlands where the agricultural fields, the main floral biomass and the areas which have the highest grazing value, are limited to narrow valleys filled with redeposited loessial sediments. The headcut migration and gully development in the region were studied between 1990 and 2001 in 3 representative drainage basins (Zipporim, Revivim and Sekher). These processes have been active for the last few millennia. If they continue in the future, the Negev Highlands region will lose its agricultural potential
