Interpretation; Apollo 9 photography of parts of southern Arizona and southern New Mexico
J. Robert Owen, Lynn M. Shown
1973, Open-File Report 73-215
Examination of small-scale (approximately 1:650,000) multispectral photographs obtained on the Apollo 9 mission in March 1969 revealed that in semiarid, regions features due to differences in soils or quantity of vegetation could most easily be discriminated on the color infrared photographs. Where there is sufficient ground truth, it is possible...
Low-flow characteristics of streams in the Puget Sound region, Washington
F.T. Hidaka
1973, Open-File Report 72-163
Periods of low streamflow are usually the most critical factor in relation to most water uses. The purpose of this report is to present data on low-flow characteristics of streams in the Puget Sound region, Washington, and to briefly explain some of the factors that influence low flow in the...
Appraisal of ground water for irrigation in the Little Falls area, Morrison County, Minnesota
John O. Helgesen
1973, Water Supply Paper 2009-D
Anticipated irrigation on sandy soils has prompted evaluation of ground-water supply potential in the Little Falls area. Geologic conditions cause ground-water availability to vary widely in the area. The largest and most readily available groundwater source is the glacial outwash sand and gravel from which the soils were derived. Test augering...
Chemical interactions of aluminum with aqueous silica at 25 degrees Celsius
John David Hem, C. E. Roberson, Carol J. Lind, W.L. Polxer
1973, Water Supply Paper 1827-E
Solutions containing from 10 -5 to 10 -2 moles per liter of aluminum and dissolved silica in various ratios were aged at pH levels between 4 and 10 at 25?C. A colloidal amorphous product having the composition of halloysite was produced in most solutions. It had a consistent and reversible...
Water resources data for Florida, water year 1972: Part 2. Water quality records
Water Resources Division, U.S. Geological Survey
1973, Water Data Report FL-72-2
Water-resources investigations of the U. S. Geological Survey include the collection of water quality data on the chemical and physical characteristics of surface- and ground-water supplies of the Nation. These data for the 1972 water year for the quality of surface waters in Florida are presented in this report. The...
Ground water in the Eugene-Springfield area, southern Willamette Valley, Oregon
F. J. Frank
1973, Water Supply Paper 2018
The cities of Eugene and Springfield and their outlying suburban and rural districts constitute an area of rapid population growth where progressively greater volumes of ground water are being required for irrigation and industrial and public supplies. The area is also one of diverse geologic and hydrologic conditions. As used...
Generalization of stream-temperature data in Washington
M. R. Collings
1973, Water Supply Paper 2029-B
The effect of water temperature on the ecosystem of streams necessitates an analysis of various physical characteristics that influence stream temperatures. This study was conducted to determine (1) the effective relations that define site-to-site variation in stream temperatures, (2) equations and methods to estimate stream temperatures at sites where little...
Water resources data for Montana, water year 1972; part 2, water quality records
Water Resources Division, U.S. Geological Survey
1973, Water Data Report MT-72-2
Water resources data for the 1972 water year for Montana include records of data for the chemical and physical characteristics of surface water. Data on the quality of surface water (chemical, temperature, and sediment) were collected from designated sampling sites at predetermined intervals such as once daily, weekly, monthly or...
