Study and interpretation of the chemical characteristics of natural water
John David Hem
1985, Water Supply Paper 2254
The chemical composition of natural water is derived from many different sources of solutes, including gases and aerosols from the atmosphere, weathering and erosion of rocks and soil, solution or precipitation reactions occurring below the land surface, and cultural effects resulting from human activities. Broad interrelationships among these processes and...

M. S. Allen, R.R. Tidball, R.M. Samater, G.I. Selner
1985, Open-File Report 85-5
Panned-concentrate samples from wadi sediments were collected over terranes of Precambrian age intrusive, volcanic, sedimentary, and metamorphic rocks, within the Jabal Habashi quadrangle, sheet 26F, Kingdom of Saudi Arabia. Multivariate analysis of the chemical data indicates that a significant base-metal association occurs in three areas within the quadrangle. An association...
Spirit Lake dam-failure flood routing assessment
D. L. Kresch
1985, Open-File Report 82-770
Potential clear-water floodflows resulting from uncontrolled breaching by Spirit Lake of a debris dam deposited by the May 18 , 1980, eruption of Mount St. Helens, Washington, were evaluated. U.S. Geological Survey dam-break model K-634 was utilized, first to compute clear-water flood hydrographs for various hypothetical breach scenarios, and then...
Simulation of an aquifer test on the Tesuque Pueblo Grant, New Mexico
Glenn A. Hearne
1985, Water Supply Paper 2206
An aquifer test was designed and conducted in the anisotropic dipping beds of the Tesuque Formation on the Tesuque Pueblo Grant, New Mexico. The three-dimensional digital model used to analyze the test approximated the response to the test. The analysis of the geohydrology of the test site in combination with...
Mathematical model of the Tesuque aquifer system near Pojoaque, New Mexico
Glenn A. Hearne
1985, Water Supply Paper 2205
A three-dimensional digital model of ground-water flow was constructed to represent the dipping anisotropic beds of the Tesuque aquifer system underlying the Pojoaque River basin and vicinity, New Mexico. Simulations of steady-state conditions and historical ground-water withdrawals were consistent with observed data. The model was used to simulate the response...
