Development of ground water from the Carrizo sand and Wilcox group in Dimmit, Zavala, Maverick, Frio, Atacosa, Median, Bexar, Live Oak, McMullen, La Salle, and Webb Counties, Texas
E. A. Moulder
1957, Open-File Report 57-77
The development of ground water for irrigation from the Carrizo sand south and southwest of San Antonio, Tex., has increased rapidly during the past few years. Declining pumping water levels in irrigation wells, caused by increased withdrawals, have caused considerable concern among the residents of the area. In response, the...
A regional gravity survey of the Cuyuna Iron Range, Minnesota
George Austin Durfee
1957, Open-File Report 57-41
A regional gravity survey of the Cuyuna Iron Range, Minnesota, was conducted during the summer of 1955 by the U. S. Geological Survey. It was believed that gravity data would aid in the understanding of the major structures of the range. It was found that synclinal and steeply dipping structures...
Floods of July 1956 in Clarke County, Alabama
L.B. Peirce
1957, Open-File Report 57-87
A weak tropical disturbance formed just off the coast of Alabama on July 5, 1956. Moving inland over the southeastern part of the State, the storm produced heavy rains on the 7th and the morning of the 8th before it dissipated and moved out toward the north....
Hydrology and water law: what is their future common ground?
Arthur M. Piper, Harold E. Thomas
1957, Open-File Report 57-90
We live in an age of social and economic evolution--evolution so deep reaching and rapid it constitutes ad revolution in numerous fields of human concern. Long-standing concepts of what is appropriate and orderly face drastic modification if they are to survive. To this situation the principles of applied hydrology and...
Surface water supply of eastern and central North Carolina
Edward B. Rice
1957, Open-File Report 57-96
None of the many factors that influence the economic growth of eastern and central North Carolina plays a more important role than water. Adequate water supply for municipal, rural domestic, industrial, and agricultural uses, is a basic need of any region....
Drainage area data for Alabama streams
J.S. Stallings, L.B. Peirce
1957, Open-File Report 57-106
The drainage area of a river basin is an important parameter in many engineering equations used for hydrologic design. It is not a parameter, however, that always requires precise measurement. Factors in the hydrologic cycle such as rainfall, runoff, transpiration, and infiltration cannot be measured nearly as closely as drainage...
Glacial features and surficial deposits of the Malaspina district, Alaska
George Plafker, Don John Miller
1957, Open-File Report 57-91
The Malaspina district extends about 50 miles along the north shore of the Gulf of Alaska from Icy Bay and the Guyot Glacier on the west to Yakutat Bay and Disenchantment Bay on the east (see index map). The district includes a coastal lowland flanked on the north by a...
Ground water and permafrost at Bethel, Alaska
Roger M. Waller
1957, Open-File Report 57-116
This report is a result of a study of the results of a test-drilling program conducted by the Alaska Department of Health to determine whether a ground-water supply is available in the village of Bethel, Alaska. The U. S. Geological Survey was asked to assist in evaluating the available information...
A field method for the determination of calcium and magnesium in limestone and dolomite
Leonard Shapiro, Walter Wallace Brannock
1957, Open-File Report 57-99
The method is an adaptation of a procedure described by Betz and Noll1 in 1950. Calcium and magnesium are determined by visual titration using Versene (disodium ethylenediamine tetraacetate) with Murexide (ammonium purpurate) as the indicator for calcium and Eriochrome Black T as the indicator for magnesium....
