Evapotranspiration and the water budget of prairie potholes in North Dakota
J.B. Shjeflo
1968, Professional Paper 585-B
The mass-transfer method was used to study the hydrologic behavior of 10 prairie potholes in central North Dakota during the 5-year period 1960-64. Many of the potholes went dry when precipitation was low. The average evapotranspiration during the May to October period each year was 2.11 feet, and the...
Geology, hydrology, and geochemistry of the Black Creek watershed near Mocanaqua, Luzerne County, Pennsylvania
Thomas Gwyn Newport, Harry E. Koester, Marion Joseph Bergin
1968, Open-File Report 71-343
The Black Creek watershed is in the southwestern end of the Northern Anthracite field in Luzerne County, northeastern Pennsylvania. The study of the watershed described in this report is designated as Project No. 2 in the Joint Federal-State Acid Mine Drainage Pollution Control Demonstration Program. The area studied encompasses the...
Fresh and saline ground-water zones in the Punjab region, West Pakistan
W.V. Swarzenski
1968, Water Supply Paper 1608-I
An extensive program of test drilling and water sampling, undertaken by the Water and Soils Investigation Division (WASID) of the West Pakistan Water and Power Development Authority (WAPDA) to evaluate hydrologic problems related to waterlogging and soil salinity, has furnished data for the delineation of fresh and saline ground-water zones...
Water data for metropolitan areas: A summary of data from 222 areas in the United States
1968, Water Supply Paper 1871
Expansion of metropolitan areas poses persistent problems in management of the hydrologic environment. Adequate hydrologic data are prerequisite to proper planning and engineering design of urban environments. Some such data are available and are tabulated for each Standard Metropolitan Statistical Area in the United States. Information for each area consists...
Infrared imagery of Lordsburg-Silver City area, New Mexico
Walden P. Pratt
1968, Open-File Report 68-218
Night time infrared imagery of the area between Lordsburg and Silver City, New Mexico, indicates numerous applications of studies of the geology and hydrology of desert regions. Tertiary volcanic rocks consisting of flows and welded tuffs show good tonal contrasts within themselves. Precambrian granites and gneisses appear mottled. Water courses...
Ground-water geology of Kordofan Province, Sudan
Harry G. Rodis, Abdulla Hassan, Lutfi Wahadan
1968, Water Supply Paper 1757-J
For much of Kordofan Province, surface-water supplies collected and stored in hafirs, fulas, and tebeldi trees are almost completely appropriated for present needs, and water from wells must serve as the base for future economic and cultural development. This report describes the results of a reconnaissance hydrogeologic investigation of the...
Electrical analog analysis of ground-water depletion in central Arizona
T. W. Anderson
1968, Water Supply Paper 1860
The Salt River Valley and the lower Santa Cruz River basin are the two largest agricultural areas in Arizona. The extensive use of ground water for irrigation has resulted in the need for a thorough appraisal of the present and future ground-water resources. The ground-water reservoir provides 80 percent (3.2...
Hydrology of Crater, East and Davis Lakes, Oregon; with section on Chemistry of the Lakes
Kenneth N. Phillips, A. S. Van Denburgh
1968, Water Supply Paper 1859-E
Crater, East, and Davis Lakes are small bodies of fresh water that occupy topographically closed basins in Holocene volcanic terrane. Because the annual water supply exceeds annual evaporation, water must be lost by seepage from each lake. The seepage rates vary widely both in volume and in percentage of the...
Ground-water hydrology of the Sevier Desert, Utah
R. W. Mower, R.D. Feltis
1968, Water Supply Paper 1854
The Sevier Desert, as used in this report, comprises the main part of the Sevier Desert, the Tintic Valley, and the southeastern part of the Old River Bed. It covers an area of about 3,000 square miles and occupies a large basin in the eastern part of the Basin and...
Ground-water hydrology of the Chad Basin in Bornu and Dikwa Emirates, northeastern Nigeria, with special emphasis on the flow life of the artesian system
Raymond E. Miller, R.H. Johnston, J.A.I. Olowu, J.U. Uzoma
1968, Water Supply Paper 1757-I
Bornu and Dikwa Emirates lie in the Nigerian sector of the Chad Basin, a vast region of interior drainage encompassing about 600,000 square miles of north-central Africa. The report area includes about 25,000 square miles of the basin that lie in Nigeria. Most of the area is a featureless plain...
Land evaluation studies with remote sensors in the infrared and radar regions
David S. Simonett
1968, Open-File Report 68-250
This paper reviews the literature, especially of the last two years, dealing with remote sensor evaluation of surface and shallow sub-surface characteristics, employing remote sensors in the infrared (1.5p. - 14p.) and radar (0.5 cm - 100 cm) regions. Imaging and non-imaging sensors are examined to assess their current status...
Application of ultraviolet reflectance and stimulated luminescence to the remote detection of natural materials
William R. Hemphill
1968, Open-File Report 68-126
Carbonate rocks and evaporite deposits commonly exhibit relatively high reflectance in the ultraviolet (<3600A), and some outcrops of these materials are selectively shown on ultraviolet imagery. Other materials which are commonly strongly imaged on ultraviolet imagery and photography include water, snow, concrete, and metallic objects, particularly aluminum.Outdoor tests of an...
Infrared survey of the Pisgah Crater area, San Bernardino County, California - a geologic interpretation
Stephen J. Gawarecki
1968, Open-File Report 69-104
The infrared survey of the Pisgah Crater Area, San Bernardino County, California was primarily undertaken to establish parameters by which rock types, structures, and textures peculiar to this locale could be recognized or differentiated. A secondary purpose was to provide an adequate evaluation and calibration of airborne and ground-based instruments...
Flood profile study, Squaw Creek, Linn County, Iowa
Water Resources Division, U.S. Geological Survey
1968, Open-File Report 68-302
This report is the result of a cooperative agreement between the city of Cedar Rapids and the U.S. Geological Survey that provides for the collection of hydrologic data by the Geologic Survey on small streams in and near the city. The city furnished the large-scale topographic map showing a stream...
Generalized hydrology of prairie potholes on the Coteau du Missouri, North Dakota
William Stewart Eisenlohr, Charles E. Sloan
1968, Circular 558
This report presents all the information, obtained during the investigation, that lends itself to generalization. It describes conditions on that part of the Coteau du Missouri where there is little integration of drainage systems. The surface of the glacial drift in this region is dotted with shallow depressions known as...
