Experiments With Fresh‐Water Barrier to Prevent Sea Water Intrusion

Artificial Recharging of Water‐Bearing Formations

“…At Camp Cooke, near the mouth of Santa Ynez River, a weir was constructed across the valley with its crest 5 ft higher than high-tide level so as to increase recharge to the well area and to prevent tidewater intrusion (4) . Recharge basins at EI Segundo and Redondo Beach were tried for the purpose of building up a fresh-water ridge (5). Because of adverse conditions encountered in the basin area, the use of diffusion wells was next studied and found satisfactory for production of a water barrier if the wells were spaced at 500-ft intervals and the water was properly conditioned (6).…”

“…The purpose of this study will be to determine: [1] the rate of discharge in terms of well production per foot of head; [2] the head recovery; [3] the recharged water recovery; [4] the method by which diffusion can best be determined; [5] the effect of injection water temperature; [6] the cost of recharge; and [7] the physical factors effecting recharge operations. This study will be conducted in full cooperation with the staff of the Federal-State Cooperative Water Level Study Project.…”

Sea Water Intrusion in California

“….,; As a result of these cooperative studies, several detailed re-ports have been prepared and submitted to the State Water Resources Board (2,6,7,8). In addition to the above mentioned formal publications, numerous reports on the problem of sea water intrusion in California have appeared in various technical journals (9)(10)(11)(12)(13)(14).…”

Development of a Fresh‐Water Barrier in Southern California for the Prevention of Sea Water Intrusion

“…Preliminary geologic exploration and theoretical considerations involved in creating a pressure mound within a pressure aquifer were published in 1953 (5).…”
