el-Far'a & Our Research Area
The Wadi al-Far'a and its watershed comprise a valley 20 km long,
descending east from Nablus to the Jordan River, and up to 2 km wide.
The wadi's perennial flow is supplied by fourteen springs, the most
famous of which is 'Ayn al-Far'a (Overview of Middle East Water Sources,
USAID, 1998, p. 26). The Wadi comprises the largest traditional water
source still available to the Palestinian population of the West Bank,
and is the second largest source of agricultural produce.
