The Emma Bell deposit, Siskiyou Co., California: A possible low-grade source of chromite
B. R. Lipin, Nicholas Wetzel, S. M. Heinrich
1983, Open-File Report 83-816
The Emma Bell chromite deposit in Siskiyou County, California contains over 5 million tons of dunite averaging about 4 percent Cr2O3. Chromite is not evenly disseminated throughout the dunite, however. For the most part the deposit consists of many chromite-rich bands in sharp contact with, and separated by, common dunite...

Effects of sanitary sewers on ground-water levels and streams in Nassau and Suffolk Counties, New York, part 1: Geohydrology, modeling strategy, and regional evaluation
T. E. Reilly, H. T. Buxton, O.L. Franke, R. L. Wait
1983, Water-Resources Investigations Report 82-4045
A computer simulation of Long Island 's regional groundwater system has been used to evaluate the effects that new-installed sewers will have on ground-water levels. Results indicate maximum water-table decliners of as much as up to 18 feet in central Nassau County and about 9 feet in Suffolk County. Total...

The Southern Hills regional aquifer system of southeastern Louisiana and southwestern Mississippi
A. Buono
1983, Water-Resources Investigations Report 83-4189
The Southern Hills regional aquifer system, named in a petition to the Environmental Protection Agency for designation as a sole or principal source of drinking water, is the primary source of public and domestic supplies in the northern 10 parishes of southeastern Louisiana. The gulfward dipping and thickening, complexly interbedded...
Water resources of the Santa Fe River basin, Florida
J. D. Hunn, L. J. Slack
1983, Water-Resources Investigations Report 83-4075
The Santa Fe River basin is a 1,384 square-mile area in north-central Florida. The principal source of water is the Floridan aquifer, a sequence of limestone beds, the upper 300 to 800 feet of which contain potable water. The western part of the basin has the greatest potential yields for...

Meteorological, water-temperature, and discharge data for the Mattole River basin, Humboldt County, California
R.D. Noble, Alan P. Jackman
1983, Water-Resources Investigations Report 78-81
To overcome a major difficulty in the testing of the validity of river-temperature models - the lack of adequate precise synoptic data for an entire river basin - synoptic meteorologic, water-temperature, and discharge data were obtained in the Mattole River Basin in northern California during the period June 10 through...
Use of flumes in measuring discharge
F. A. Kilpatrick, V.R. Schneider
1983, Techniques of Water-Resources Investigations 03-A14
Flumes for measuring discharge are usually of two general groups-critical-flow flumes and supercritical-flow flumes. In this chapter, the underlying design principles for each group are discussed; the most commonly used flumes are described and their discharge ratings presented. There is also discussion of considerations in choosing and fitting the appropriate...

Mineral and energy resources of the continental margins of the United States arc important to the Nation's commodity independence and to its balance of payments. These resources are being studied along the continental margins of the Atlantic Ocean and the Gulf of Mexico in keeping with the mission of the...
A two-dimensional graphing program for the Tektronix 4050-series graphics computers
K.L. Kipp
1983, Water-Resources Investigations Report 83-4087
A refined, two-dimensional graph-plotting program was developed for use on Tektronix 4050-series graphics computers. Important features of this program include: any combination of logarithmic and linear axes, optional automatic scaling and numbering of the axes, multiple-curve plots, character or drawn symbol-point plotting, optional cartridge-tape data input and plot-format storage, optional...
Reconnaissance of surface-water resources in the Kobuk River basin, Alaska, 1979-80
J.M. Childers, D.R. Kernodle
1983, Water-Resources Investigations Report 83-4027
Surface water data were collected at selected sites in the Kobuk River Basin in northwest Alaska in August 1979 and April 1980. In August 1979, frequent heavy rains caused abnormally high flows in the basin; unit runoff values, computed from discharge measurements at 25 sites, ranged from 0.08 to 12.2...

Use of previously coded and tested subroutines simplifies and speeds up program development and testing. This report presents routines that can be used to calculate various probability distributions and other functions of importance in statistical hydrology. The routines are designed as general-purpose Fortran subroutines and functions to be called from...
Initial assessment of time of travel and mixing through Gulf Island Pond and the lower Androscoggin River, Maine
G.W. Parker, G.S. Hunt
1983, Water-Resources Investigations Report 83-4020
Flow-stratification patterns were observed in Gulf Island Pond during time-of-travel studies in May and August 1980. The stratification patterns in this 70 million cubic-meter impoundment were due to a temperature differences between inflowing water and reservoir water. Separation was observed at temperature differences of 0.5 degrees C in May 1980...
