2007, Professional Paper 1703-J
The timing and location of streamflow in the San Pedro River are partially dependent on the aerial distribution of recharge in the Sierra Vista subwatershed. Previous investigators have assumed that recharge in the subwatershed occurs only along the mountain fronts by way of stream-channel infiltration near the contact between low-permeability...

Ground-water recharge in the arid and semiarid southwestern United States
David A. Stonestrom, Jim Constantz, Ty P.A. Ferré, Stanley A. Leake, editor(s)
2007, Professional Paper 1703
Ground-water recharge in the arid and semiarid southwestern United States results from the complex interplay of climate, geology, and vegetation across widely ranging spatial and temporal scales. Present-day recharge tends to be narrowly focused in time and space. Widespread water-table declines accompanied agricultural development during the twentieth century, demonstrating that...
