River channel bars and dunes - Theory of kinematic waves
Walter Basil Langbein, Luna Bergere Leopold
1968, Professional Paper 422-L
A kinematic wave is a grouping cf moving objects in zones along a flow path and through which the objects pass. These concentrations may be characterized by a simple relation between the speed of the moving objects and their spacing as a result of interaction between them.Vehicular traffic has long...
Gold in meteorites and in the earth's crust
Robert Sprague Jones
1968, Circular 603
The reported gold contents of meteorites range from 0.0003 to 8.74 parts per million. Gold is siderophilic, and the greatest amounts in meteorites are in the iron phases. Estimates ,of the gold content of the earth's crust are in the range of 0.001 to 0.006 parts per million....
Water temperatures in the lower Columbia River
Albert M. Moore
1968, Circular 551
Daily observations of water temperature for 20 sites in the lower Columbia River are presented in tabular form and in profile form by months for the period August 1941 to July 1942. The profiles show minimum, mean (average), and maximum water temperatures for those months from river mile 142 to...
Estimated use of water in the United States, 1965
Charles Richard Murray
1968, Circular 556
Estimates of water use in the United States for 1965 indicate that an average of about 310 bgd (billion gallons per day) were withdrawn for public-supply, rural domestic and livestock, irrigation, and industrial (including thermoelectric power)uses--that is, about 1,600 gallons per capita per day. This represents an increase of 15...
Gold distribution on the sea floor off the Klamath Mountains, California
George William Moore, Eli A. Silver
1968, Circular 605
Analyses of 82 samples collected from the surface of the continental shelf between the Oregon-California border and Eureka, Calif., indicate that the background gold content on this shelf is about 0.1 ppb (part per billion). Four anomalous tracts, which range in extent from 10 to 30 square kilometers, have gold...
Rutile and topaz in Precambrian gneiss, Jefferson and Clear Creek Counties, Colorado
Douglas M. Sheridan, Richard B. Taylor, Sherman P. Marsh
1968, Circular 567
Disseminated rutile and major amounts of topaz have been identified in Precambrian topaz-quartz gneiss northwest of Evergreen, Colo. The rutile occurs in quartz-topaz-sillimanite gneiss that forms a stratigraphic unit which is 11 to 100 feet thick and is identified along strike for more than 7,000 feet. Three composite chip samples...
