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...

Map showing the potentiometric surface of the Magothy aquifer in southern Maryland, August 1980
Frederick K. Mack, Judith C. Wheeler, Stephen E. Curtin
1981, Open-File Report 81-633
This map is based on measurements made in a network of 77 observation wells. Highest levels of the potentiometric surface, 61 to 64 feet above sea level, were near the outcrop or subcrop of the aquifer in topographically high areas of Anne Arundel and northern Prince Georges Counties. The potentiometric...
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...

1981, Open-File Report 81-220
The need for large quantities of energy has created interest in the Fort Union coal region of the Northern Great Plains. Extensive development of this coal, which may include onsite steam-power generation, gasification, liquefaction, and slurry-pipeline transport of the coal from this region, would place a heavy demand on the...

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 81-636
The eastern region of the Interior Coal Province has been divided into 11 hydrologic study areas. Area 25, located in west-central Illinois, includes the Spoon River and small tributaries to the Illinois River. Pennsylvanian age rocks underlie most of the study area. Illinois, with the largest reserves of bituminous coal,...

1981, Open-File Report 81-542
A requirement of Public Law 95-87, the Surface Mining Control and Reclamation Act of 1977, is the understanding of the hydrology in actual and proposed surface-mined areas. Surface-water data for small specific-sites and for larger areas such as adjacent and general areas are needed also to satisfy the hydrologic requirements...
