1984, Professional Paper 1342
The southern California uplift culminated in 1974 as a 150- km-wide crustal swell that extended about 600 km eastward and east-southeastward from Point Arguello to the Colorado River and Salton Sea, respectively; it was characterized by remarkably uniform height changes between 1959 and 1974 of 0.30-0.35 m over at least...

H. T. Mitten
1984, Water-Resources Investigations Report 83-4246
The U.S. Geological Survey, in cooperation with Fresno County, is developing a computer model of the unconfined aquifer system in the Fresno area. In the area, consolidated rocks are overlain by unconsolidated deposits. The unconsolidated deposits are divided into a lower fine-grained unit and an overlying coarse-grained unit. The system...

P.M. Montazer, W.E. Wilson
1984, Water-Resources Investigations Report 84-4345
The unsaturated volcanic tuffs beneath Yucca Mountain, Nevada, are being evaluated as a host rock for a potential repository for high-level radioactive waste. A conceptual hydrologic model is proposed to describe the flow of fluids through these rocks. Thickness of the unsaturated zone is about 500 to 750 meters and...
Habitat Suitability Index Models: Muskrat
Arthur W. Allen, Robert D. Hoffman
1984, FWS/OBS 82/10.46
The muskrat (Ondatra zibethicus) is the most valuable semi-aquatic furbearer in North America, with a total fur trade income in the millions of dollars (Willner et al. 1980). With the exception of Florida, and coastal Georgia and South Carol ina, native and introduced populations of muskrats occur throughout most of...

1984, Water-Resources Investigations Report 84-4170
A 5-month partial study (February to July 1983) was completed in Suisun Bay, a shallow embayment of San Francisco Bay, Calif., to determine characteristic heavy metal concentrations present in sediments and organisms (Corbicula clams) prior to possible discharge of San Luis Drain irrigation tile return water. Preliminary results show sediments...
Effects of relocating State Route 151 on the flood profiles of Conotton Creek and its tributaries between Bowerston and Scio, Ohio
W.P. Bartlett, B. E. Krejmas, R.I. Mayo, S. W. Wandle
1984, Water-Resources Investigations Report 83-4130
The Ohio Department of Transportation proposes to relocate an 8-mile segment of State Route 151 between Bowerston and Scio, Harrison County, Ohio. About 3.1 miles of this relocated highway will be within the flood plain of Conotton Creek or its tributaries. Water-surface profiles of the 100-year flood along Conotton Creek...
Development of a model to predict the adsorption of lead from solution on a natural streambed sediment
David Wayne Brown, John David Hem
1984, Water Supply Paper 2187
Adsorption of solutes by solid mineral surfaces commonly influences the dissolved ionic composition of natural waters. A model based on electrical double-layer theory has been developed which appears to be capable of characterizing the surface chemical behavior of a natural fine-grained sediment containing mostly quartz and feldspar. This variable surface...

1984, Water-Resources Investigations Report 83-4280
A two-dimensional, finite-element, digital model was developed for the Carmel Valley alluvial ground-water basin using measured, computed, and estimated discharge and recharge data for the basin. Discharge data included evapotranspiration by phreatophytes and agricultural, municipal, and domestic pumpage. Recharge data included river leakage, tributary runoff, and pumping return flow. Recharge...

S. P. Garabedian
1984, Open-File Report 84-461
A nonlinear, least-squares regression technique for the estimation of ground-water flow model parameters was applied to the regional aquifer underlying the eastern Snake River Plain, Idaho. The computer program simulates two-dimensional, steady-state ground-water flow. Hydrologic data for the 1980 water year were used to calculate recharge rates, boundary fluxes, and...
