Vertical displacement measurements in Central California with a long-baseline two-fluid tiltmeter
Howard C. Merchant
1981, Open-File Report 81-885
The need for a water-tube tiltmeter and the details of its operation were covered by Eaton [1] in 1959. Since that time more modern instrumentation has allowed modification and further development beyond the basic single-tube fluid tiltmeter with a mechanical surface sensor. A number of instruments are discussed in connection...

Effects of residential wastewater treatment systems on ground-water quality in west-central Jefferson County, Colorado
Dennis C. Hall, D. E. Hillier, Edward Nickum, W.G. Dorrance
1981, Open-File Report 81-73
The use of residential wastewater-treatment systems in Evergreen Meadows, Marshdale, and Herzman Mesa, Colo., has degraded ground-water quality to some extent in each community. Age of community; average lot size; slope of land surface; composition, permeability, and thickness of surficial material; density, size , and orientation of fractures; maintenance of...

Evapotranspiration from rapidly growing young saltcedar in the Gila River Valley of Arizona
O.E. Leppanen
1981, Open-File Report 81-485
Estimates of evapotranspiration by young saltcedar, based on energy budget measurements, were made for an unfilled portion of the San Carlos Reservoir in east-central Arizona. Foty-eight days of record were obtained before the site was inundated. The young saltcedar, which had grown from seed earlier in the season , had...
Baseline studies of the feasibility and reliability of using animal behavior as a component in the prediction of earthquakes
Dale F. Lott, Benjamin L. Hart, Kenneth L. Verosub
1981, Open-File Report 81-378
This project was established to determine if it were possible to advance the state of the art in earthquake prediction by learning more about claims that unusual animal behavior was an earthquake precursor. We used intensive post-earthquake interview surveys to gather objective reports both of instances of unusual animal behavior...
Radionuclide concentrations in streams in the upper Blackfoot River basin, southeastern Idaho
Walton H. Low
1981, Open-File Report 81-142
Data on radionuclide concentrations in water and sediment material in the phosphate-mining area of the upper Blackfoot River basin were collected from May to October 1979. Maximum measured uranium and radium-226 concentrations dissolved in water were 3.7 micrograms per liter and 1.8 picocuries per liter , respectively. Maximum measured uranium...
Low flow of streams in Fairfax County, Virginia
E. H. Mohler, G. F. Hagan
1981, Open-File Report 81-63
The effect of geologic differences and urban development on low-flow characteristics of streams in Fairfax County, Va., are discussed. Tables of annual minimum 7-day average flow values for various recurrence intervals are presented for 5 long-term gaging stations and for 37 selected low-flow measurement sites. Drainage-basin boundaries and 7-day 10-year...
Predicted effects on ground water of construction of Divide Cut section, Tennessee-Tombigbee Waterway, northeastern Mississippi, using a digital model
Mark S. McBride
1981, Open-File Report 81-649
The Tennessee-Tombigbee Waterway, connecting the Tennessee River in northeastern Mississippi with the Gulf of Mexico, is currently (1980) under construction. The Divide Section, the northernmost 39 miles of the Waterway, will consist, from north to south, of (1) a dredged channel, (2) the Divide Cut, and (3) an artifical lake...

1981, Open-File Report 81-350
The Ohio Department of Transportation, Division of Highways, proposes to replace a three-span arch, bridge across Paint Creek on South Paint Street in Chillicothe, Ohio with a new deck-type structure resting on four sets of piles and four piers. Profiles of the 10-, 25-, 50- and 100-year floods under present...

1981, Open-File Report 80-1298
Hydrologic and chemical data were collected during base-flow conditions on three streams in southeastern Montana from October 26 to November 5, 1977, to characterize groundwater discharge. Maximum measured flow of Otter Creek, an interrupted stream, was 1.2 cubic feet per second. The water chemistry was dominated by sodium, magnesium, and...
