Ground Water in Carbonate Rocks and Regolith in the Fairview Area, Tennessee
From abstract: Fourteen test wells drilled in the Fairview area, Tennessee, produce from 3 to 100 gallons per minute and have an average yield of 32 gallons per minute; yields were measured while blowing water from the wells with compressed air. In comparison, the average yield of 134 supply wells reported by drillers is 13 gallons per minute. Specific capacities for three of the test wells ranged from 0.3 to 0.6 gallons per minute per foot of drawdown after 8 hours of pumping at 20 to 47 gallons per minute. Two test wells had specific capacities of 1.1 and 0.4 gallons per minute per foot of drawdown after 72 hours of pumping at 55 and 43 gallons per minute.

Reconnaissance of Surface-Water Resources in the Kobuk River Basin, Alaska, 1979-80
From introduction: This report contains data on physiographic and climatic characteristics of the Kobuk River basin, as well as stream channel hydraulic properties, seasonal quantity and quality of surface waters, floods, channel erosion, and benthic invertebrates. The data show the magnitude and ranges of stream discharge, width, depth, and velocity, of flow that can be expected in late winter and summer periods, and indicate flood and erosion hazards in the basin.

Primary Productivity by Phytoplankton in the Tidal, Fresh Potomac River, Maryland, May 1980 to August 1981
Purpose and scope: The purpose of this study was to determine primary productivity and respiration of the fresh, tidal Potomac River. The data will be used by the authors and other researchers involved in modelling chemical and biological properties to calculate phytoplankton growth rates. Methods are documented in detail so that the report could serve as a reference. The report covers the period from May 1980 through August 1981. Five stations were selected for study that are representative of biologically important reaches of the fresh, tidal Potomac River.

Backwater and Discharge at Highway Crossing with Multiple Bridges in Louisiana and Mississippi
Purpose and Scope: The principal objective of this project was to measure the backwater and discharge distribution for multiple bridges. These data have been used to determine if the methods developed by Schneider and others (1976) for single-opening highway crossings could be applied to multiple bridges. In addition, the method developed by Tracey and Carter (1955) and Cragwall (1958) was modified to use the procedure proposed by Schneider and others (1976) to calculate friction losses in the approach reach. This modified procedure was then also tested.
