Ground water in the Twenty-Nine Palms Indian Reservation and vicinity, San Bernardino County, California
J. R. Freckleton
1982, Water-Resources Investigations Report 82-4060
The Twenty-Nine Palms Indian Reservation is in San Bernardino County, California. Movement of ground water in the area is impeded locally by faults which act as ground-water barriers. There are indications that a fault probably crosses the reservation in an east-west direction; such a fault may interfere with ground-water pumping....
Streamflow losses to Madison Group rocks in the Little Belt and Big Snowy Mountains, Montana
R.D. Feltis, Ronald R. Shields
1982, Water-Resources Investigations Report 82-49
Four streams originating in the Little Belt and Big Snowy Mountains in central Montana were measured in 1975 to determine streamflow losses across outcrops of the Madison Group (Mississippian age). Based on streamflow data obtained for 39 months at two streamflow-gaging stations on the Middle Fork Judith River, the average...
Measurement of time of travel and dispersion in streams by dye tracing
E. F. Hubbard, F. A. Kilpatrick, L.A. Martens, J. F. Wilson Jr.
1982, Techniques of Water-Resources Investigations 03-A9
The use of fluorescent dyes and tracing techniques provides a means for measuring the time-of-travel and dispersion characteristics of steady and gradually varied flow in streams. Measurements of the dispersion and concentration of dyes give insight into the behavior of soluble contaminants that may be introduced into a stream. This manual describes methods of measuring time...
Evaluation of the streamflow-data program in Pennsylvania
Herbert N. Flippo Jr.
1982, Water-Resources Investigations Report 82-21
The stream-gaging program in Pennsylvania is subject to budgetary constraints in the next several years. Elimination of those gaging stations that have no current-purpose use and little utility in providing regional flow-characteristic information is the most effective way to reduce costs. The efficient design of a network of gaging stations for obtaining regional information...
Uranium-series dating of mollusks and corals, and age of Pleistocene deposits, Chesapeake Bay area, Virginia and Maryland
Robert B. Mixon, Barney J. Szabo, James Patrick Owens
1982, Professional Paper 1067-E
Geologic mapping in conjunction with uranium-series dating of fossil mollusks and corals suggests that the low-lying ( < 17 m in altitude) terrace deposits in the central and southern Chesapeake Bay area include two main depositional sequences, each of which represents a high stand of the sea in late Pleistocene...
Determination of ultimate carbonaceous BOD and the specific rate constant (K1)
J. K. Stamer, J. P. Bennett, Stuart W. McKenzie
1982, Open-File Report 82-645
Ultimate carbonaceous biochemical oxygen demand (BODu) and the specific rate constant (K1) at which the demand is exerted are important parameters in designing biological wastewater treatment plants and in assessing the impact of wastewater on receiving streams. An analytical method is presented which uses time-series concentrations of BOD, defined as...
Approximate water-level changes in wells in the Chicot and Evangeline aquifers, 1977-82 and 1981-82, and measured compaction 1973-82, in the Houston-Galveston region, Texas
J. L. Strause, C.E. Ranzau Jr.
1982, Open-File Report 82-328
This report, which was prepared in cooperation with the City of Houston, the Harris-Galveston Coastal Subsidence District, and the Texas Department of Water Resources, presents data on water-level changes during 1977-82 and 1981-82 in the Chicot and Evangeline aquifers (fig. 1-4) and data on measured compaction 1973-82 (fig. 5). During...
