Environmental framework of ground‐water contamination
H. E. LeGrand
1965, Groundwater (3) 11-15
Ramifications of contamination are increasingly involved in the majority of ground‐water problems. The volume of usable ground water is shrinking in many places because of dispersion of contaminated water. Consideration of ground‐water contamination as a multitude of independent problems, separately solvable as each problem arises, is outmoded; wise policies, relating water supply to contamination potential, are needed to alleviate and to forestall problems. Methodology of...
Relation of carbon 14 concentrations to saline water contamination of coastal aquifers
B.B. Hanshaw, W. Back, Meyer Rubin, Robert L. Wait
1965, Water Resources Management (1) 109-114
Naturally occurring stable or radioactive isotopes may be used in some places to identify the origin of saline water that contaminates some coastal aquifers. In a recent study to determine the origin of saline water in the Ocala Limestone aquifer near Brunswick, Georgia, the following sources were analyzed for C14 and...
Earthquake magnitudes from hydroseismic data
R.C. Vorhis
1965, Groundwater (3) 12-20
If earthquakes are recorded on your water‐level charts, you can make your own estimate of earthquake magnitudes! As an aid in doing this, this paper presents two graphs: one to calculate distance from well to earthquake epicenter; the other, a nomogram from which to read hydroseismic magnitude plus log C. Examples given show (1) direct computation of...
Mathematical models of catchment behavior
David R. Dawdy, Terence O’Donnell
1965, Journal of the Hydraulics Division (91) 123-137
After an examination of trends in the modeling of hydrologic systems, a review of some recent studies is given. The authors' preliminary studies on the feasibility and efficiency of the automatic evaluation of catchment model parameters by use of a digital computer are described and some results presented....
