- Not to be confused with Wadi al-Far'a (Palestinian village on the bank of the homonymous river)
Wadi al-Far'a (Arabic name) or
Nahal Tirza (Hebrew name) is a river in the northern
West Bank that empties into the
Jordan River south of
Damia Bridge (Arabic: Jisr Damiya). It is the largest stream in the West Bank. Wadi al-Far'a is located in the rugged area of the West Bank and cuts east through the
Jordan Valley, passing through the
Palestinian village of
Wadi al-Far'a. The Tirzah Reservoir is used to collect the floodwater of Wadi al-Far'a before it flows into the Jordan River.
