Saline-water resources of Texas
Allen George Winslow, Lester Ray Kister
1956, Water Supply Paper 1365
Large quantities of saline water are available in the world, both on the surface and underground; however, these waters have not been studied extensively as sources of potable water. Saline water is defined herein as water containing more than 1,000 parts per million of dissolved solids, or, with certain mineralized irrigation...
Relationship of sediment discharge to streamflow
B. R. Colby
1956, Open-File Report 56-27
The relationship between rate of sediment discharge and rate of water discharge at a cross section of a stream is frequently expressed by an average curve. This curve is the sediment rating curve. It has been widely used in the computation of average sediment discharge from water discharge for periods...
Bibliography and index of U.S. Geological Survey trace elements and related reports through June 1956
Paul E. Soister, Dora R. Conklin, Mary D. Bowman, Water Resources Division, U.S. Geological Survey
1956, Trace Elements Investigations 600
This bibliography supersedes TEI-500, "U. S. Geological Survey Trace Elements and related reports through 1954." Part I is a numerical list of U. S. Geological Survey Trace Elements Investigations and Memorandum reports. This part lists reports that have been transmitted to the U. S. Atomic Energy Comission and also reports...
Summary of reconnaissance for radioactive deposits in Alaska, 1945-1954, and an appraisal of Alaskan uranium possibilities
Helmuth Wedow Jr.
1956, Trace Elements Investigations 577
In the period 1945-1954 over 100 investigations for radioactive source materials were made in Alaska. The nature of these investigations ranged from field examinations of individual prospects or the laboratory analysis of significantly radioactive samples submitted by prospectors to reconnaissance studies of large districts. In this period no deposits of...
The deuterium blance of Lake Maracaibo
Irving Friedman, Daniel R. Norton, D.B. Carter, A.C. Redfield
1956, Limnology and Oceanography (1) 239-246
A balance sheet for the gains and losses of deuterium from Lake Maracaibo, using estimates based on climatological data for the exchanges of water and measurements of the deuterium content of lake water, rainfall, river flow, and Caribbean Sea water to obtain the volumes of the deuterium exchange, indicates that...
Factors controlling the concentrations of thirteen rare metals in sea-water
K.B. Krauskopf
1956, Geochimica et Cosmochimica Acta (9) 1-32
The following factors controlling the concentrations of thirteen metals (Zn, Cu, Pb, Bi, Cd, Ni, Co, Hg, Ag, Cr, Mo, W, V) in sea-water were studied:1. precipitation of insoluble compounds with ions normally present in aerated sea-water,2. precipitation of sulphides locally in reducing environments,<br...
The progressive lag of sediment concentration with flood waves
Sumner Griggs Heidel
1956, Eos, Transactions, American Geophysical Union (37) 56-66
Numerous investigations of suspended‐sediment discharge have shown that an increase in stream flow usually is accompanied by an increase in sediment concentration. The sediment‐concentration peak during a rise may precede, coincide with, or follow the water‐discharge peak. Observations on the Bighorn River in Wyoming and Montana show a progressive lag...
The spectrophotometric determination of vanadium as thiocyanate in acetone-water medium
H.I. Feinstein
1956, Analytica Chimica Acta (15) 141-144
A method devised for the spectrophotometric determination of vanadium in acetone-water medium is based on the reaction between vanadium (IV) and thiocyanate. Within the concentration limits tested, Beers law is obeyed.This method is not as sensitive as the peroxide method, but the vanadium(IV)-thiocyanate reaction product shows greater absorbancy...
Prediction of ground‐water levels on basis of rainfall and temperate correlations 
Matthew Irvin Rorabaugh
1956, Eos, Transactions, American Geophysical Union (37) 436-441
A method for predicting ground‐water levels in the glacial‐outwash deposits in the Ohio River valley near Louisville involves development of curves by graphical correlation to define the effects of winter precipitation and winter temperature on recharge to the water table, and to determine the decline of the water table as...
Numerical analysis of regional water levels to define aquifer hydrology
Robert W. Stallman
1956, Eos, Transactions, American Geophysical Union (37) 451-460
Two fundamental methods for studying aquifer hydrology are now in use. The first, applied many years ago, consists of detailed observation of aquifer inflow, outflow, and storage changes, and their variations in time. By analysis of these observations, estimates of the perennial recharge to the aquifer and other pertinent hydrologic...
Tidal fluctuations of water level observed in wells in East Tennessee
R. M. Richardson
1956, Eos, Transactions, American Geophysical Union (37) 461-462
Semidiurnal water‐level fluctuations of tidal period have been observed in wells completed in the Chickamauga limestone of Middle and Late Ordovician age in east Tennessee. The periodic oscillations of the water level are similar to fluctuations in artesian pressure that in other localities have been recognized and correlated with earth...
Forecasting the dry‐weather flow of Pond Creek, Oklahoma: A progress report
William E. Clark
1956, Eos, Transactions, American Geophysical Union (37) 442-450
Pond Creek in west‐central Oklahoma drains an area of 319 sq mi above the gaging station near Fort Cobb, Caddo County. Ground water, contained in the Permian Rush Springs sandstone under water‐table conditions, moves toward the creek at an almost unchanging rate. The discharge of ground water into the creek...
