Uranium values from ion-filter water sampling compared with values from bulk-water sampling
Robert Allen Cadigan, J. Karen Felmlee
1978, Open-File Report 78-472
Analytical values of uranium from well water sampled by means of ion-filters were compared with analytical values of the same water sampled by the standard bulk (1-liter) water-sampling technique (Brown, Skougstad and Fishman, 1970). A fluorometric extraction method of analysis was used on both sets of samples. Duplicate samples from...

Hot, deep origin of petroleum: shelf and shallow basin evidence and application
Leigh C. Price
1978, Open-File Report 78-1021
Oil and gas pools in shallow basins or on the shallow, stable shelves of deeper sedimentary basins may not be exceptions to the model of a hot deep origin of petroleum. The oil in shallow basins is directly associated with faulting extending out of the deepest parts of the basin....
Bottom currents and bottom sediment distribution in Massachusetts Bay

1978, Open-File Report 78-369
Massachusetts Bay is a coastal Bay 100 km long and 40 km wide located in the western Gulf of Maine. The Bay is open only to the Gulf to the east; the opening is partially blocked by a shallow bank. The bottom sediment distribution in the bay is complex; fine...
Exceedance probability-depth relationships of floods for Maryland streams west of Chesapeake Bay
William J. Herb
1978, Open-File Report 78-171
A procedure is outlined for estimating the depths of floods of specified exceedance probabilities for Maryland streams west of the Chesapeake Bay. Data required for use of the estimating procedure are the stream's location in one of three flood-depth regions and the drainage area. Regression equations developed for depth estimation...
Hydrogeologic conditions in the town of Shelter Island, Suffolk County, Long Island, New York
Julian Soren
1978, Water-Resources Investigations Report 77-77
Shelter Island, an area of about 11 square miles, in Suffolk County, N.Y., is situated between the north and south forks of eastern Long Island. The upper glacial aquifer is the sole source of freshwater supply for Shelter Island 's population, which currently ranges seasonally from 2,000 to 8,000. Fresh...
Estimation of ground motion parameters
David M. Boore, Adolph A. Oliver III, Robert A. Page, William B. Joyner
1978, Open-File Report 78-509
Strong motion data from western North America for earthquakes of magnitude greater than 5 are examined to provide the basis for estimating peak acceleration, velocity, displacement, and duration as a function of distance for three magnitude classes. Data from the San Fernando earthquake are examined to assess the effects of...
Digital model of ground-water flow in the Piceance Basin, Rio Blanco and Garfield Counties, Colorado
John B. Weeks
1978, Water-Resources Investigations Report 78-46
The digital model used to simulate ground-water flow in the aquifer system in the basin drained by Piceance and Yellow Creeks in northwestern Colorado is described in detail. The model is quasi three-dimensional in that it simulates ground-water flow in a multiaquifer system by assuming horizontal flow in the aquifers...
Water resources of No Name Valley, Colville Indian Reservation, Washington
Denzel R. Cline
1978, Open-File Report 78-122
No Name Creek valley is a trough cut in granitic bedrock in north-central Washington. A low topographic divide in the northern third of the valley separates it into the No Name Creek basin on the south and Omak Creek basin on the north. Omak Creek is the larger stream and...
Estimates of 7-day, 10-year minimum flows at selected stream sites in Puerto Rico
Ernest D. Cobb
1978, Open-File Report 78-583
The 7-day, 10-year minimum flow of streams is used as an index for determining the capacity of streams to receive waste effluents. This index of flow was computed from streamflow records for 31 stream sites in Puerto Rico. In addition, there was a need for the 7-day, 10-year minimum flow...

Plan of study for the High Plains regional aquifer-system analysis in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming
John B. Weeks
1978, Water-Resources Investigations Report 78-70
The Ogallala Formation and associated Tertiary and Quarternary deposits form the principal aquifers supporting irrigation in the High Plains of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming. The volume of water in storage within the aquifers is declining in most of the High Plains because water...

Sedimentation in Hot Creek in vicinity of Hot Creek Fish Hatchery, Mono County, California
D. E. Burkham
1978, Open-File Report 78-661
An accumulation of fine-grained sediment in Hot Creek downstream from Hot Creek Fish Hatchery created concern that the site may be deteriorating as a habitat for trout. The accumulation is a phenomenon that probably occurs naturally in the problem reach. Fluctuation in the weather probably is the basic cause of...
