| Abstract: | When using surface infiltration as a method of recharge, infiltration testing is considered an important additional data
input along with other hydrogeologic data into the recharge decision. As part of an investigation into the potential for groundwater
recharge, two desert basins in Jordan (Wadi Madoneh and Wadi Butum) were investigated to determine the possibility of recharge
using floodwater retention structures. For each area, short-duration (up to 7-h) infiltration tests were conducted to estimate
surface infiltration capacity of the upper soil layers in order to present to the authorities preliminary information which
could be used along with other factors to aid in the selection of the best site for a pilot recharge project. Given the highly
fractured rock formations that constitute the underlying aquifers in the two areas, it was assumed that the upper alluvium
layers are the limiting factors in transmitting water to target aquifers. The infiltration tests conducted to estimate the
recharge characteristics of the recharge sites yielded test results that indicated a representative infiltration rate of 0.44 m/day
for the Wadi Madoneh site and 0.197 m/day for the Wadi Butum site. The data input was used subsequently with other decision
factors to select the most promising site for the pilot project.
