Autocorrelation of rainfall and streamflow minimums
N.C. Matalas
1963, Professional Paper 434-B
Hydrologic time series of annual minimum mean monthly rainfall and annual minimum 1-day and 7-day discharge, considered as drought indices, were used to study the distribution of droughts with respect to time. The rainfall data were found to be nearly random. The discharge data, however, were found to be nonrandomly...
Effects of drought in central and south Texas
H. E. Thomas
1963, Professional Paper 372-C
The effects of drought upon ground-water storage and discharge, and upon streamflow, vary tremendously in the central third of Texas (the area from the Panhandle to the Gulf of Mexico). Extremes are represented by (a) the Llano Estacado, where the drought had negligible effect upon ground-water resources, which are being...
Ground-water geology and pump irrigation in Frenchman Creek Basin above Palisade, Nebraska
W. D. E. Cardwell, Edward D. Jenkins
1963, Water Supply Paper 1577
This report describes the geography, geology, and ground-water resources of that part of the Frenchman Creek basin upstream from Palisade, Nebr., an area of about 4,900 square miles. The basin includes all of Phillips County, Colo., and Chase County, Nebr., and parts of Logan, Sedgwick, Washington, and Yuma Counties, Colo.,...
Evaporation control research, 1959-60
Water Resources Division, U.S. Geological Survey
1963, Water Supply Paper 1692
Two hundred and forty-five dispersions of long-chain alkanols were formulated by using various emulsifiers and alkanols. The dispensing and spreading ability of each of these formulations was tested. The most promising emulsifier that could be used with any of the alkanols was glyceryl monostearate (self-emulsifying). However, the concentration of the...
Variations in the chemical character of the Susquehanna River at Harrisburg, Pennsylvania
Peter W. Anderson
1963, Water Supply Paper 1779-B
The chemical quality of the Susquehanna River at Harrisburg is influenced by three major factors: streamflow, anthracite and bituminous coal-mine drainage, and geology. Water samples collected at Harrisburg near the west bank of the Susquehanna River and those of western tributaries that drain limestone terranes are similar in chemical quality....
Ground-water geology of Karnes County, Texas
Robert B. Anders
1963, Water Supply Paper 1539-G
The exposed rocks and those underlying Karnes County dip toward the Gulf of Mexico at average rates ranging from 20 to more than 200 feet per mile. The oil fields are on structures associated with faulting; the effect of faulting on the occurrence of ground water has not been determined. The...
Ground-water geology of Bexar County, Texas
Ted Arnow
1963, Water Supply Paper 1588
The investigation in Bexar County was part of a comprehensive study of a large area in south-central Texas underlain by the Edwards and associated limestones (Comanche Peak and Georgetown) of Cretaceous age. The limestones form an aquifer which supplies water to the city of San Antonio, several military installations, many...
Ground-water geology of Grayson County, Texas
E.T. Baker
1963, Water Supply Paper 1646
Grayson County in north-central Texas is near the north edge of the West Gulf Coastal Plain. The county has an area of 927 square miles and had an estimated population of 79,500 in 1957. The major town is Sherman, which has an estimated population of 31,000. The northern two-thirds of...
Determination of beta activity in water
F. B. Barker, B.P. Robinson
1963, Water Supply Paper 1696-A
Many elements have one or more naturally radioactive isotopes, and several hundred other radionuclides have been produced artificially. Radioactive substances may be present in natural water as a result of geochemical processes or the release of radioactive waste and other nuclear debris to the environment. The Geological Survey has developed...
Progress report on the ground-water resources of the Louisville area, Kentucky, 1949-55
Edwin A. Bell, Robert W. Kellogg, Willis K. Kulp
1963, Water Supply Paper 1579
In the Louisville area, the principal water-bearing formations are the glacial-outwash sand and gravel and, in places, the underlying limestone. During the period 1949 through 1955 pumpage from the two aquifers averaged about 30 mgd (million gallons per day). The pumpage was approximately in balance with the normal net recharge...
Factors influencing the occurrence of floods in a humid region of diverse terrain
M. A. Benson
1963, Water Supply Paper 1580-B
This report describes relations between flood peaks and hydrologic factors in a humid region with limited climatic variation but a diversity of terrain. Statistical multiple-regression techniques have been applied to hydrologic data on New England. Many topographic and climatic factors have been evaluated. and their relations to flood peaks have...
