Water resources of the Upper Colorado River Basin - basic data
William Vaughn Iorns, C. H. Hembree, D. A. Phoenix, G.L. Oakland
1964, Professional Paper 442
This is the basic data section of a report by the U.S. Geological Survey on the water resources of the Upper Colorado River Basin. This section contains tables of duration of water discharge at 176 stream-gaging sites, monthly and annual summaries of chemical quality and sediment data at sites of...
Giant Upper Cretaceous oysters from the Gulf coast and Caribbean
Norman F. Sohl, Erle G. Kauffman
1964, Professional Paper 483-H
Two unusually massive ostreid species, representing the largest and youngest Mesozoic members of their respective lineages, occur in Upper Cretaceous sediment of the gulf coast and Caribbean areas. Their characteristics and significance, as well as the morphologic terminology of ostreids in general, are discussed. Crassostrea cusseta Sohl and Kauffman n. sp....
Geology and ground-water conditions in the Wilmington-Reading area, Massachusetts
John Augustus Baker, H.G. Healy, O. M. Hackett
1964, Water Supply Paper 1694
The Wilmington-Reading area, as defined for this report, contains the headwaters of the Ipswich River in northeastern Massachusetts. Since World War II the growth of communities in this area and the change in character of some of them from rural to suburban have created new water problems and intensified old...
Geology and ground-water resources of Richardson County, Nebraska
Philip A. Emery
1964, Water Supply Paper 1779-W
Richardson County is in the extreme southeast corner of Nebraska. It has an area of 545 square miles, and in 1960 it had a population of 13,903. The county is in the physiographic region referred to as the Dissected Loess-covered Till Prairies. Major drainage consists of the Big Nemaha River,...
Availability of ground water in parts of the Acoma and Laguna Indian Reservations, New Mexico
George A. Dinwiddie, Ward Sundt Motts
1964, Water Supply Paper 1576-E
The need for additional water has increased in recent years on the Acoma and Laguna Indian Reservations in west-central New Mexico because the population and per capita use of water have increased; the tribes also desire water for light industry, for more modern schools, and to increase their irrigation program....
Field measurement of alkalinity and pH
Ivan Barnes
1964, Water Supply Paper 1535-H
The behavior of electrometric pH equipment under field conditions departs from the behavior predicted from Nernst's law. The response is a linear function of pH, and hence measured pH values may be corrected to true pH if the instrument is calibrated with two reference solutions for each measurement. Alkalinity titrations...
Ground-water provinces of southern Rhodesia
Philip Eldon Dennis, L.L. Hindson
1964, Water Supply Paper 1757-D
Ground-water development, utilization, and occurrence in nine ground-water provinces of Southern Rhodesia are summarized in this report. Water obtained from drilled wells for domestic and stock use has played an important part in the social and economic development of Southern Rhodesia from the beginnings of European settlement to the present....
Apparatus and techniques for measuring bedload
David Wellington Hubbell
1964, Water Supply Paper 1748
The need for accurate determinations of the total sediment discharge of particles of bedload size has prompted this investigation of available and possible measuring apparatus and procedures. The accuracy of measurements of sediment discharge made with trap-type samplers is affected by the variability of sampler efficiency, by the oscillatory variation...
