The State of Utah sustained direct damages from landslides and flooding in excess of $400 million during approximately three months in the spring of 1983. These disastrous events were declared national disaster areas (Anderson and others, 1985)....
Geohydrology of the Foothill ground-water basin near Santa Barbara, California
J. R. Freckleton
1989, Water-Resources Investigations Report 89-4017
Geohydrologic data presented in this report indicate that the East Subbasin of the Goleta groundwater basin and Storage Unit II of the Santa Barbara groundwater basin should be considered as a separate groundwater basin, which is referred to as the Foothill groundwater basin in this report. The 4.5 sq-mi Foothill...
Estimation of flood-frequency characteristics and the effects of urbanization for streams in the Philadelphia, Pennsylvania area
J.F. Bailey, W.O. Thomas Jr., K. L. Wetzel, T.J. Ross
1989, Water-Resources Investigations Report 87-4194
This report provides a method for estimating the magnitude and frequency of floods for small streams in the Philadelphia, Pennsylvania area. Data collected at 21 streamflow gaging stations were used in a multiple-regression analysis to develop equations for computation of peak-flow characteristics. The flood equations were determined by relating flood-frequency...
Use of temperature profiles beneath streams to determine rates of vertical ground-water flow and vertical hydraulic conductivity
Wayne W. Lapham
1989, Water Supply Paper 2337
The use of temperature profiles beneath streams to determine rates of vertical ground-water flow and effective vertical hydraulic conductivity of sediments was evaluated at three field sites by use of a model that numerically solves the partial differential equation governing simultaneous vertical flow of fluid and heat in the Earth....

Results of a geochemical survey, Wadi Ash Shu'Bah quadrangle, sheet 26E, Kingdom of Saudi Arabia
W. R. Miller, M. A. Arnold
1989, Open-File Report 89-337
The interpretation of geochemical data of a regional survey of the Wadi ash Shu'bah quadrangle resulted in the selection of areas for follow-up studies. The results of the detailed geochemical studies of these areas, combined with field observation, resulted in the identification of areas of moderate and high mineral resource...

Descriptive statistics and spatial distributions of geochemical variables associated with manganese oxide-rich phases in the northern Pacific
Joseph Moses Botbol, Gerald Ian Evenden
1989, Bulletin 1863
Tables, graphs, and maps are used to portray the frequency characteristics and spatial distribution of manganese oxide-rich phase geochemical data, to characterize the northern Pacific in terms of publicly available nodule geochemical data, and to develop data portrayal methods that will facilitate data analysis. Source data are a subset of...

1989, Open-File Report 89-229
Water quality sampling was conducted at eight sites on the Clark Fork and selected tributaries from Galen to Missoula, Mont., from October 1987 through September 1988. This report presents tabulations and statistical summaries of the water quality data. Included in this report are tabulations of streamflow, onsite water quality, and...
Flow of ground water through fractured carbonate rocks in the Prairie du Chien-Jordan Aquifer, southeastern Minnesota

1989, Open-File Report 89-253
Contamination of groundwater from point and nonpoint sources (such as landfills, feedlots, agricultural chemicals applied to fields, and septic systems) is a recognized problem in the karst area of southeastern Minnesota. The US Geological Survey, in cooperation with the Minnesota Department of Natural Resources and the Legislative Commission on Minnesota...

Mass-conserving method of characteristics for streamflow modeling
W. G. Sikonia
1989, Open-File Report 89-414
A robust numerical model is presented for the computation of unsteady streamflow on steep river slopes. The one-dimensional model uses the method of characteristics on a specified space-time grid to solve the Saint-Venant equations. An additional continuity equation requirement on each space-time element provides greatly improved conservation of mass over...
