Water-budget studies of lower Mesilla Valley and El Paso Valley, El Paso County, Texas
W.R. Meyer, J.D. Gordon
1973, Open-File Report 73-185
The total inflow of water to the lower Mesilla Valley in 1970 was 390,510 acre-feet. Of this amount, 43,300 acre-feet was consumptively used by crops and phreatophytes and 4,700 acre-feet was lost by evaporation. Ground-water storage increased by 320 acre-feet, and 360,860 acrefeet left the valley as surface- and ground-water...
Bottom features and processes related to drifting ice on the Arctic shelf, Alaska
Erk Reimnitz, Peter W. Barnes, Tau Rho Alpha
1973, Miscellaneous Field Studies Map 532
Early investigations of artic shelf regions led to the hypothesis that certain micro-relief forms are related to the action of grounded ice (for example, Rex, 1955). Since the introduction of side-scan sonar as a tool for ocean-floor surveys, a number of workers have described the occurrence of linear bottom features...

1973, Water Supply Paper 2009-D
Anticipated irrigation on sandy soils has prompted evaluation of ground-water supply potential in the Little Falls area. Geologic conditions cause ground-water availability to vary widely in the area. The largest and most readily available groundwater source is the glacial outwash sand and gravel from which the soils were derived. Test augering...
