Relation between proposed developments of water resources and seepage from the All-American Canal, eastern Imperial Valley, California
Omar J. Loeltz, S. A. Leake
1979, Open-File Report 79-744
A two-layer digital model designed for this study indicated that sealing of the Coachella branch of the All-American Canal would cause an eventual increase in seepage from the All-American Canal of about 15,000 acre-feet annually. Sealing of both the Coachella Canal and the segment of the All-American Canal between Pilot...
