Methods for analysis of selected metals in water by atomic absorption
Marvin J. Fishman, Sanford C. Downs
1966, Water Supply Paper 1540-C
This manual describes atomic-absorption-spectroscopy methods for determining calcium, copper, lithium, magnesium, manganese, potassium, sodium, strontium and zinc in atmospheric precipitation, fresh waters, and brines. The procedures are intended to be used by water quality laboratories of the Water Resources Division of the U.S. Geological Survey. Detailed procedures, calculations, and methods...
Effect of vertical motion on current meters
Nicholas A. Kallio
1966, Water Supply Paper 1869-B
The effect of vertical motion on the performance of current meters at various stream velocities was evaluated to determine whether accurate discharge measurements can be made from a bobbing boat. Three types of current meters--Ott, Price, and vane types--were tested under conditions simulating a bobbing boat. A known frequency and...
Special sediment investigations Mississippi River at St. Louis, Missouri, 1961-63
Cloyd H. Scott, Howard D. Stephens
1966, Water Supply Paper 1819-J
Four sets of comprehensive hydraulic and sediment data were obtained during 1961-63 for the Mississippi River at St. Louis at ranges of mean velocity from 3.3 to 5.6 feet per second, of mean depth from 22 to 37 feet, of width from 1,570 to 1,670 feet, of mean water-surface slope...

1966, Water Supply Paper 1807
Sheridan County is in the north-central part of Wyoming and is an area of about 2,500 square miles. The western part of the county is in the Bighorn Mountains, and the eastern part is in the Powder River structural basin. Principal streams are the Powder and Tongue Rivers, which are...
Salinity of the ground water in western Pinal County, Arizona
Lester Ray Kister, W. F. Hardt
1966, Water Supply Paper 1819-E
The chemical quality of the ground water in western Pinal County is nonuniform areally and stratigraphically. The main areas of highly mineralized water are near Casa Grande and near Coolidge. Striking differences have been noted in the quality of water from different depths in the same well. Water from one...
Hydrology of the Upper Capibaribe Basin, Pernambuco, Brazil - A reconnaissance in an Area of Crystalline Rocks
Luiz Goncalves Chada Filho, Mario Dias Pessoa, William C. Sinclair
1966, Water Supply Paper 1663-E
The upper Capibaribe basin is the western three-fourths, approximately, of the valley of the river that empties into the Atlantic Ocean at Recife, the capital of the State of Pernambuco, Brazil. It is the part of the drainage basin that is within the Drought Polygon of northeast Brazil, and it...
Summary of hydrologic conditions of the Louisville area, Kentucky
Edwin Allen Bell
1966, Water Supply Paper 1819-C
Water problems and their solutions have been associated with the growth and development of the Louisville area for more than a century. Many hydrologic data that aided water users in the past can be applied to present water problems and will be helpful for solving many similar problems in the...
