Thermal loading of natural streams
Alan P. Jackman, Nobuhiro Yotsukura
1977, Professional Paper 991
The impact of thermal loading on the temperature regime of natural streams is investigated by mathematical models, which describe both transport (convection-diffusion) and decay (surface dissipation) of waste heat over 1-hour or shorter time intervals. The models are derived from the principle of conservation of thermal energy for application to...
Calcic soils and calcretes in the southwestern United States
George Odell Bachman, Michael N. Machette
1977, Open-File Report 77-794
Secondary calcium carbonate of diverse origins, 'caliche' of many authors, is widespread in the southwestern United States. 'Caliche' includes various carbonates such as calcic soils and products of groundwater cementation. The term 'caliche' is generally avoided in this report in favor of such terms as calcrete, calcic soils, and pervasively...
Radioelement concentrations and preliminary radiometric ages of rocks of the Kigluaik Mountains, Seward Peninsula, Alaska
Carl Maurice Bunker, Carl E. Hedge, C.L. Sainsbury
1977, Open-File Report 77-735
A sequence of old metamorphic rocks including the Kigluaik and Nome Groups is exposed in the Kigluaik Mountains of the Seward Peninsula. The high-grade metasedimentary rocks give a whole-rock Rb-Sr age of 735 m.y. This late Precambrian age is believed to be the time of metamorphism. Orthogneisses, intrusive into the...
Movement of moisture in the unsaturated zone in a loess-mantled area, southwestern Kansas
Robert C. Prill
1977, Professional Paper 1021
A study of moisture movement associated with ponding near Garden City, Kansas, indicates that loess-manted areas have excellent potential for artificial recharge by water spreading. Infiltration stabilized at rates ranging from 0.7 to 2.2 feet (0.2 to 0.7 meter) per day reflecting changes in hydraulic conductivity of soil horizons. Results...
Sediment transport to the Fox Chain of Lakes, Illinois
Timothy P. Brabets
1977, Open-File Report 77-867
Two main tributaries to the Fox Chain of Lakes, the Fox River and Nippersink Creek, were sampled twice weekly and during periods of high runoff to determine the amount of suspended inorganic sediment being transported into the Chain of Lakes. Sediment yields were determined by using the transport-duration technique. It...
Artificial recharge to a freshwater-sensitive brackish-water sand aquifer, Norfolk, Virginia
Donald L. Brown, William Dudley Silvey
1977, Professional Paper 939
Fresh water was injected into a brackish-water sand for storage and retrieval. The initial injection rate of 400 gpm decreased to 70 gpm during test 3. The specific capacity of the well decreased also, from 15.4 to 0.93 gpm. Current-meter surveys indicated uniform reduction in hydraulic conductivity of all contributing...
Paleozoic-Mesozoic boundary in the Berry Creek Quadrangle, northwestern Sierra Nevada, California
Anna Martta Hietanen
1977, Professional Paper 1027
Structural and petrologic studies in the Berry Creek quadrangle at the north end of the western metamorphic belt of the Sierra Nevada have yielded new information that helps in distinguishing between the chemically similar Paleozoic and Mesozoic rocks. The distinguishing features are structural and textural and result from different degrees...
Effects of the catastrophic flood of December 1966, north rim area, eastern Grand Canyon, Arizona
Maurice E. Cooley, B. N. Aldridge, Robert C. Euler
1977, Professional Paper 980
Precipitation from the unusual storm of December 1966 was concentrated on highlands in northern Arizona, southwestern Utah , southern Nevada, and south-central California and caused widely scattered major floods in the four States. In Arizona the largest amount of precipitation was in the north rim area of eastern Grand Canyon,...
