Acidity control in Bald Eagle Creek and West Branch Susquehanna River, Clinton County, Pennsylvania
Herbert N. Flippo Jr.
1971, Open-File Report 71-108
Regression analysis of chemical and physical data collected on Beech Creek resulted in two curves that relate the concentration of free hydrogen ion to the electrical specific conductance of the water. These curves provide a means of estimating, through use of data telemetered from a water-quality monitor on Beech Creek,...

Generalized flood-frequency estimates for urban areas in Missouri
Ector Eugene Gann
1971, Open-File Report 71-116
A method is presented for estimating flood-frequency information for urban areas in Missouri. Flood-frequency relations are presented which provide an estimate of the flood-peak discharge for floods with recurrence intervals from 2.33 to 100 years for basins with various degrees of existing or projected urban development. Drainage area sizes for...
Hulburt Creek Hydrology, Southwestern Wisconsin
Warren A. Gebert
1971, Open-File Report 71-118
The purpose of this study was to determine the hydrologic characteristics of Hulburt Creek, Sauk County, Wis., in order to evaluate a proposed reservoir. The streamflow characteristics estimated are the low flow, monthly flow, and inflow flood. The study was done by the U.S. Geological Survey in cooperation with the...

Geologic map of Late Cenozoic deposits, Santa Clara County, California
E. J. Helley, E. E. Brabb
1971, Open-File Report 71-150
This map is the first of several in the San Francisco Bay region showing the distribution and differentiation of the late Cenozoic alluvial, estuarine, and volcanic deposits. The sedimentary deposits of gravel, sand, silt, and clay were separated into geologic map units on the basis of their post-depositional soil development,...

The relation of turbulence to diffusion in open-channel flows
Thomas N. Keefer
1971, Open-File Report 72-206
This investigation examines the interrelation between turbulent diffusion, dispersion, and the statistical properties of turbulence in an open-channel flow. The experiments were conducted in a 3. 87- foot wide flume over four boundary roughnesses. The results are from studies made of: (1) the influence of turbulence on the vertical and...
