Influence of climate on progressive hillslope failure in Redwood Creek Valley, northwestern California
Douglas N. Swanston, Robert Ruhl Ziemer, Richard J. Janda
1983, Open-File Report 83-259
Both creep and earthflow processes control hillslope erosion over large parts of the Redwood Creek basin. The type of process and displacement rates are largely dependent on underlying bedrock type and precipitation input. Progressive creep with rates ranging from 1.0 to 2.5 mm/a dominates on slopes west of the Grogen...
Ground water in carbonate rocks and regolith in the Fairview area, Tennessee
C.R. Burchett, Ann Zurawski, A.K. Sparkes, E. F. Hollyday
1983, Water-Resources Investigations Report 83-4134
Fourteen test wells drilled in the Fairview area, Tennessee, produce from 3 to 100 gallons per minute and have an average yield of 32 gallons per minute, measured while blowing water from the wells with compressed air. In comparison, the average yield of supply wells reported by drillers is 13...
Reconnaissance of benthic invertebrates from tributary streams of the Yampa and North Platte River basins, northwestern Colorado
L. J. Britton
1983, Water-Resources Investigations Report 83-4191
Benthic invertebrates were collected from tributaries of the Yampa River in Routt and Moffat Counties, and tributaries of the North Platte River in Jackson County. Field water-quality measurements of water temperature, specific conductance, pH, dissolved oxygen, and bed material size were also made to aid in assessing stream water-quality conditions....
Hydrology and subsidence potential of proposed coal-lease tracts in Delta County, Colorado
Tom Brooks
1983, Water-Resources Investigations Report 83-4069
Potential subsidence from underground coal mining and associated hydrologic impacts were investigated at two coal-lease tracts in Delta County, Colorado. Alteration of existing flow systems could affect water users in the surrounding area. The Mesaverde Formation transmits little ground water because of the neglibile transmissivity of the 1,300 feet of...
Assessment of gray whale feeding grounds and sea floor interaction in the northeastern Bering Sea
C.H. Nelson, K.R. Johnson, John H. Barber
1983, Open-File Report 83-727
A dense ampeliscid amphipod community in Chirikov Basin and around St. Lawrence Island in the northeastern Bering Sea has been outlined by summarizing biological studies, analyzing bioturbation in sediment samples, and examining sea floor photos and videotapes. The amphipod population is associated with a homogeneous, relict fine-grained sand body 0.10-1.5...
Historical surface deformation near Oildale, California
Robert O. Castle, Jack P. Church, Robert F. Yerkes, John C. Manning
1983, Professional Paper 1245
Historical surface deformation recognized in the southern San Joaquin Valley and adjacent Sierra Nevada foothills near Oildale, Calif., includes: normal and apparently aseismic dip slip along four faults; subsidence within or adjacent to the Kern Front, Poso Creek, Mount Poso, and Fruitvale oil fields; and uplift of much of the...
Application of digital mapping technology to the display of hydrologic information; a proof-of-concept test in the Fox-Wolf River Basin, Wisconsin
G. K. Moore, L.G. Baten, G.J. Allord, C.J. Robinove
1983, Water-Resources Investigations Report 83-4142
The Fox-Wolf River basin in east-central Wisconsin was selected to test concepts for a water-resources information system using digital mapping technology. This basin of 16,800 sq km is typical of many areas in the country. Fifty digital data sets were included in the Fox-Wolf information system. Many data sets were...
Surface-water quality in the Campbell Creek basin, Anchorage, Alaska
T. P. Brabets, L.A. Wittenberg
1983, Water-Resources Investigations Report 83-4096
Four streams in the Campbell Creek Basin were sampled during different flow conditions for an 18-month period. North Fork Campbell and South Fork Campbell Creeks drain areas virtually undisturbed by man 's activities. The other two streams, Little Campbell Creek and the main stem Campbell Creek, drain areas that have...
Water resources data, Alabama, water year 1982
H.C. Rollins, F.C. Sedberry, E.G. Ming, I.A. Giles
1983, Water Data Report AL-82-1
Water resources data for the 1982 water year for Alabama consist of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and water levels in wells. This report contains discharge records for 85 gaging stations; stage only for 16 gaging stations, stage and...
Mineral resource potential map of the Mount Eddy and Castle Crags Roadless Areas, Shasta, Siskiyou, and Trinity counties, California
Jocelyn A. Peterson, Mary E. Caress, David K. Denton, James M. Spear
1983, Miscellaneous Field Studies Map 1529-B
Although ultramafic terranes such as that underlying the Mount Eddy and Castle Crags Roadless Areas may contain chromite, nickel, platinum-group metals, cobalt, and asbestos, there are no significant identified concentrations of these resources within the roadless areas. Platinum-group metals were sought but not detected in stream-sediment concentrates, although this does...
Map showing outcrops of basaltic rocks of early Quaternary and Tertiary age, Basin and Range province, Southern California
Kurt Roggensack, David A. Lopez
1983, Water-Resources Investigations Report 83-4116-G
This map report is one of a series of geologic and hydrologic maps covering all or parts of States within the Basin and Range province of the western United States. The map reports contain detailed information on subjects that characterize the geohydrology of the province, including the ground-water hydrology/ ground-water...
Graphical method for estimating occurrence and duration of a critical low flow in the Sacramento River at Freeport, California
J.G. Harmon
1983, Water-Resources Investigations Report 82-4001
Sacramento County expects to begin operation of the Sacramento Regional Wastewater Treatment Plant in 1982. The California State Water Resources Control Board has ruled that the plant will not be allowed to release effluent into the Sacramento River when flow in the river is 4,000 cubic feet per second or...
