Time of travel of solutes in the Tuscarawas River Basin, Ohio, August and September, 1974
Arthur O. Westfall, Earl E. Webber
1977, Open-File Report 77-23
A time-of-travel study was made on a 10.6-mile reach of the Tuscarawas River to determine average velocity and dispersion characteristics between selected points. The reach was divided into five subreaches, and a fluorescent dye used as a tracer material. At about the 50-percent flow-duration level, time-of-travel of the peak concentration...
Characteristics of thin-skinned style of deformation in the southern Appalachians, and potential hydrocarbon traps
Leonard Dorrean Harris, Robert C. Milici
1977, Professional Paper 1018
This paper is an attempt to focus attention on the more important characteristics of the thin-skinned style of deformation in the southern Appalachians by presenting a model to illustrate the regional anatomy and to identify likely structures that need additional investigation as possible prospects for hydrocarbon accumulation. Five distinct changes...
Late Quaternary depositional history, Holocene sea-level changes, and vertical crustal movement, southern San Francisco Bay, California
Brian F. Atwater, Charles W. Hedel, Edward J. Helley
1977, Professional Paper 1014
Sediments collected for bridge foundation studies at southern San Francisco Bay, Calif., record estuaries that formed during Sangamon (100,000 years ago) and post-Wisconsin (less than 10,000 years ago) high stands of sea level. The estuarine deposits of Sangamon and post-Wisconsin ages are separated by alluvial and eolian deposits and by...
