The Guatemalan earthquake of February 4, 1976, a preliminary report
A. F. Espinosa, editor(s)
1976, Professional Paper 1002
The Guatemalan earthquake of February 4, 1976, with a surface-wave magnitude of 7.5, was generated by left-lateral slippage on the Motagua fault and was felt over an area of at least 100,000 km2. This earthquake claimed more than 22,700 lives and injured more than 76,000 people. The preliminary estimate of...
Limnological survey of Sacony Creek Basin, Berks County, Pennsylvania
James L. Barker, Kenneth P. Kulp
1976, Water-Resources Investigations Report 76-84
Samples of water, fish and benthic macroinvertabrates collected at 10 sampling stations over a 10-month period indicate that Sacony Creek and its major tributaries contain water of good to excellent quality. The waters were found to be free of excessive quantities of dissolved nutrients, oxidizable matter, and fecal coliform bacteria. (p>Fish...

Summary of geology and ground-water resources of Passaic County, New Jersey
L.D. Carswell, J.G. Rooney
1976, Water-Resources Investigations Report 76-75
Ground water in Passaic County occurs in intergranular openings of unconsolidated stratified deposits of Quaternary age and in joints and fractures in consolidated rocks of Precambrian, Paleozoic, and Triassic age.The Brunswick Formation of Triassic age is the most important aquifer in the southeastern one-third of Passaic County. Reported yields of public supply and...
Geohydrology of the Albin and La Grange areas, aoutheastern Wyoming
W. B. Borchert
1976, Water-Resources Investigations Report 76-118
The Albin and La Grange areas in southeastern Wyoming are two adjoining different hydrologic areas. Since ground water is the only source of water for irrigation in the Albin area, 34 irrigation wells have been drilled since 1968 and developed in conjunction mostly with center-pivot sprinkler systems that in 1974...
The Meridian-upper Wilcox aquifer in Mississippi
E. H. Boswell
1976, Water-Resources Investigations Report 76-79
The Meridian-upper Wilcox aquifer contains freshwater in a 15 ,000 sq mi area in northwestern and central Mississippi. The aquifer comprises the Meridian Sand Member of the Tallahatta Formation and discontinuous hydraulically connected sand beds in the upper part of the Wilcox Group. The aggregate sand thickness of the aquifer...

Technical manual for estimating low-flow frequency characteristics of streams in the Susquehanna River basin
Jeffrey T. Armbruster
1976, Water-Resources Investigations Report 76-51
This report presents procedures for estimating low-flow frequency characteristics for streams in the Susquehanna River basin. The techniques can be used at ungaged sites as well as sites where insufficient data are available to make a reliable estimate. Streams have been divided intp two types--major and minor. Major streams are...
Availability and chemical characteristics of ground water in central La Plata County, Colorado
R. E. Brogden, T.F. Giles
1976, Water-Resources Investigations Report 76-69
The central part of La Plata County, Colo., has undergone rapid population growth in recent years. This growth has resulted in an increased demand for information for additional domestic, industrial, and municipal water supplies. A knowledge of the occurrence of ground water will permit a more efficient allocation of the...
Effects of off-road vehicle use on the hydrology and landscape of arid environments in central and southern California
Charles T. Snyder, D. G. Frickel, R. F. Hadley, R.F. Miller
1976, Water-Resources Investigations Report 76-99
Two widely separated sites in California used for motorcycle hill-climbing were studied to evaluate the impact on the landscape and hydrology. At Panoche Hills in central California, an area formerly used by motorcycles together with an adjacent unused area were monitored from 1971 to 1975. Observations in both areas included...
Variation in concentration of selected water-quality constituents in the Sacramento River at Bend Bridge, California
Linda J. Britton, R. C. Averett
1976, Water-Resources Investigations Report 76-14
During an intensive water-quality study of the Sacramento River at Bend Bridge, Calif., from September 4 to 7, 1973, differences in selected water-quality constituent concentrations were evaluated at three locations at a single site in the river for two 24-hour periods. Water temperature, dissolved oxygen, pH, specific conductance, selected major...

Magnitude and frequency of floods in Nebraska
Emil W. Beckman
1976, Water-Resources Investigations Report 76-109
Estimates of flood characteristics with recurrence intervals up to 100 years can be obtained at most sites in Nebraska by use of techniques presented in this report. Instructions, equations, and graphs are presented to aid the design engineer in estimating the magnitude and frequency of floods. For natural-flow streams, the estimating...
Appraisal of water resources in the Hackensack River basin, New Jersey
