Relation of electrochemical potentials and iron content to ground-water flow patterns
William Back, Ivan Barnes
1965, Professional Paper 498-C
This study was undertaken to develop means of measuring oxidation potentials in aquifer systems and to use the measured values in interpreting the behavior of iron in ground water. Anne Arundel County, Md., was selected as the area of study because of the wide range of concentration of iron-nearly zero...
Variations in chemical character of water in the Englishtown Formation, New Jersey
Paul R. Seaber
1965, Professional Paper 498-B
This investigation describes the variations in the chemical character of the water in the Englishtown Formation of Late Cretaceous age in the Atlantic Coastal Plain of New Jersey, and demonstrates the application of the concept of hydrochemical mapping to the study and evaluation of water-bearing materials. The chemistry of ground water...
Resource understanding: a challenge to aerial methods
Stewart L. Udall
1965, Photogrammetric Engineering (31) 63-75
Aerial survey methods are speeding acquisition of survey data needed to provide and manage the nation's resources. These methods have been applied to topographic mapping for a number of years and the record clearly shows their advantages in terms of cost and speed in contrast to the ground methods that...
Infrared photography and imagery in water resources research
Charles J. Robinove
1965, Journal - American Water Works Association (57) 834-840
This article briefly describes the characteristics of infrared radiation and demonstrates how infrared photography and infrared imagery can be applied to water resources research, specifically to the identification and description of hydrologic features....
