Nonpoint-source discharges in Pequea Creek Basin, Pennsylvania, 1977
Janice R. Ward, David A. Eckhardt
1979, Water-Resources Investigations Report 79-88
A study of Pequea Creek included measurement of streamflow and collection of water and bottom-material samples during selected base-flow and storm periods from February to December 1977. Samples were analyzed for nitrogen and phosphorus species, suspended sediment, organic carbon, and pesticides. Daily mean constituent concentrations and discharges transported from the...
Surface water environment in the area of the San Juan Basin regional uranium study, New Mexico, Colorado, Arizona, and Utah
Mark William Busby
1979, Open-File Report 79-1499
Streamflows in the lowland areas of the San Juan Basin are highly variable, responding to short-duration, high-intensity thunderstorms occurring in the late spring and summer. The thunderstorms can cause floods of large magnitude, but of localized extent. Most streams of the lowlands are ephemeral or intermittent. Streams of the high...
Multiyear low flow in southeastern Kansas
William J. Carswell Jr.
1979, Open-File Report 79-1288
Many existing water supplies in southeastern Kansas are proving inadequate to meet current and expanded future needs. One of the methods in which the use of highly variable streamflow in the area can be evaluated is with the aid of multiyear low-flow frequency information. Data from 19 stream-gaging stations in...
Geometric considerations for an automated mapping satellite system (Mapsat)
Alden P. Colvocoresses
1979, Open-File Report 79-914
The geometry of the frame photograph whether taken from an aircraft or a satellite is well known and documented. Transforming photographs into maps is a relatively slow and expensive process which for many critical steps defies automation. A satellite offers the unique advantages of greater stability and uniform velocity over...
