River and Wadi Agricultural Systems

River and wadi systems

These are confined to the bottoms and adjacent lower terraces of rivers and wadis and depend on well-driven irrigation, pump irrigation from perennial rivers, or high water table in combination with winter precipitation. A small number of these systems use qanats and/or water harvesting techniques such as dams. These systems differ in length but are spatially similar in the sizes and patterns of fields and crops raised.
