Chemical and physical characteristics of coal and carbonaceous shale samples from the Salt Range coal field, Punjab Province, Pakistan
Peter D. Warwick, T. Shakoor, Shahid Javed, S.T.A. Mashhadi, H. Hussain, M. Anwar, M.I. Ghaznavi
1990, Open-File Report 90-524
Sixty coal and carbonaceous shale samples collected from the Paleocene Patala Formation in the Salt Range coal field, Punjab Province, Pakistan, were analyzed to examine the relationships between coal bed chemical and physical characteristics and depositional environments. Results of proximate and ultimate analyses, reported on an as received basis, indicate...
Electromagnetic, magnetic, and gravimetric surveys at the Bi'r Jarbuah gold prospect, Kingdom of Saudi Arabia
C.H. Miller, A.A. Showail, M.A. Bazzari, J.A. Khoja, M.O. Hajour
1990, Open-File Report 90-327
Bi'r Jarbuah is a potential gold-bearing site located east of the Ishmas gold district in the southeastern part of the Arabian Shield. Surface rocks are mostly diorite and granodiorite plutons and the metavolcanic and metasedimentary rocks they have intruded. Extensive thin alluvial deposits cover approximately 40 percent of the area...
Flood of December 1987 in central and eastern Arkansas
B.L. Neely Jr.
1990, Water-Resources Investigations Report 89-4188
Heavy rain fell across Arkansas during December 24-28, 1987. During this period, 6 to 12 inches of rain fell in a 100-mile wide belt extending roughly from Texarkana to West Memphis, Arkansas. The intense rainfall produced flooding throughout much of central and eastern Arkansas. Peak discharges associated with the flood...
An enhanced digital line graph design
Stephen C. Guptill
Stephen C. Guptill, editor(s)
1990, Circular 1048
In response to increasing information demands on its digital cartographic data, the U.S. Geological Survey has designed an enhanced version of the Digital Line Graph, termed Digital Line Graph - Enhanced (DLG-E). In the DLG-E model, the phenomena represented by geographic and cartographic data are termed entities. Entities represent individual...
Reconnaissance investigation of water quality, bottom sediment, and biota associated with irrigation drainage in the American Falls Reservoir area, Idaho, 1988-89
Walton H. Low, William H. Mullins
1990, Water-Resources Investigations Report 90-4120
Increased concern about the quality of irrigation drainage and its potential effects on human health, fish, and wildlife prompted the Department of the Interior to begin a program during late 1985 to identify irrigation-induced water-quality problems that might exist in the Western States. During `988, the Task Group on Irrigation...
Levels at streamflow gaging stations
E.J. Kennedy
1990, Techniques of Water-Resources Investigations 03-A19
This manual establishes the surveying procedures for (1) setting gages at a streamflow gaging station to datum and (2) checking the gages periodically for errors caused by vertical movement of the structures that support them. Surveying terms and concepts are explained, and procedures for testing, adjusting, and operating the instruments...
Technique for estimating depths of 100-year floods in Pennsylvania
Herbert N. Flippo Jr.
1990, Water-Resources Investigations Report 86-4195
Techniques are developed for estimating 100-year flood depths in natural channels of unregulated Pennsylvania streams that drain less than 2,200 square miles. Equations and graphs are presented relating the depth of the 100-year flood above median stage and drainage area in five defined hydrologic areas in the State. Another graph...
