Ground water in the Ogallala formation in the southern high plains of Texas and New Mexico
J.G. Cronin
1969, Hydrologic Atlas 330
The Ogallala Formation of Tertiary (Pliocene) age is the principal aquifer in the Southern High Plains of western Texas and eastern New Mexico. This heavily pumped aquifer supplies practically all the water used for irrigation, municipal, industrial (except oil-field repressuring), and domestic purposes. Although the ground water in the Ogallala Formation...
Measurement of discharge by the moving-boat method
George F. Smoot, Charles E. Novak
1969, Techniques of Water-Resources Investigations 03-A11
This chapter describes the procedures for measuring discharge in large streams by the moving-boat technique. During the traverse of a boat across a stream, a sonic sounder records the geometry of the cross section, and a continuously operating current meter senses the combined stream and boat velocities. These data are...
Scientific or rule-of-thumb techniques of ground-water management--Which will prevail?
Charles Lee McGuinness
1969, Circular 608
Emphasis in ground-water development, once directed largely to quantitatively minor (but sociologically vital) service of human and stock needs, is shifting: aquifers are treated as possible regulating reservoirs managed conjunctively with surface water. Too, emphasis on reducing stream pollution is stimulating interest in aquifers as possible waste-storage media. Such management...
Geologic maps of early Apollo landing sites of set C
N.J. Trask
1969, Open-File Report 70-327
Comparison of the five potential early Apollo landing sites of set C reveals significant geologic similarities and differences. No two sites are identical; the geology of each should be considered in the interpretation of returned lunar samples and observations. Geologic maps of each site have been prepared at scales of...
