Flood-hazard study: 100-year flood stage for Lucerne Lake, San Bernadino County, California
Mark William Busby
1977, Open-File Report 77-597
A study of the flood hydrology of Lucerne Valley, Calif., was made to develop the 100-year stage for Lucerne Lake. Synthetic-hydrologic techniques were used; and the 100-year flood stage was estimated to be at an elevation of 2,849.3 feet above mean sea level. Channel dimensions were measured at 59 sites...

Documentation for subroutine REDUC3, an algorithm for the linear filtering of gridded magnetic data
Richard J. Blakely
1977, Open-File Report 77-784
Subroutine REDUC3 transforms a total field anomaly h1(x,y) , measured on a horizontal and rectangular grid, into a new anomaly h2(x,y). This new anomaly is produced by the same source as h1(x,y) , but (1) is observed at a different elevation, (2) has a source with a different direction of...
Sediment transport to the Fox Chain of Lakes, Illinois
Timothy P. Brabets
1977, Open-File Report 77-867
Two main tributaries to the Fox Chain of Lakes, the Fox River and Nippersink Creek, were sampled twice weekly and during periods of high runoff to determine the amount of suspended inorganic sediment being transported into the Chain of Lakes. Sediment yields were determined by using the transport-duration technique. It...

Analyses of native water and dredged material from southern Louisiana waterways, 1975-76
Charles R. Demas, Patricia C. Higgins
1977, Open-File Report 77-503
From June 1975 to July 1976 the U.S. Geological Survey conducted nine dredging and seven postdredging studies related to water quality in selected reaches of major navigable waterways of southern Louisiana. Samples were collected from the Mississippi River-Gulf Outlet, Mississippi River at Southwest Pass, Mississippi River at New Orleans, Bayou...

Calculation of gravity and magnetic anomalies along profiles with end corrections and inverse solutions for density and magnetization
John W. Cady
1977, Open-File Report 77-463
An equation derived for the vertical gravity field due to a body with polygonal cross section and finite strike length. The equations consists of the 2-dimensional equation of Talwani, Worzel, and Landisman (1959), with the addition of end corrections. Equations for the magnetic field due to a similar body were...
