Abstract

The two experimental irrigation plots were each located in the West Bank Mountains close to Ramallah. Results of the irrigation experiments showed that precipitation-induced runoff from rock outcrops continued below ground as preferential flow along the rock–soil interface, while water from the soil surface percolated mainly vertically and much more homogeneously. This was evident from the high density soil moisture measurements, as well as from the dye tracer patterns. Outcrop runoff percolated faster and to greater depths than water infiltrating directly from the soil surface, thus possessing a greater potential for groundwater recharge
