A finite-element model study of the impact of the proposed I-326 crossing on flood stages of the Congaree River near Columbia, South Carolina
J. K. Lee, C. S. Bennett III
1981, Open-File Report 81-1194
A two-dimensional finite element surface water model was used to study the hydraulic impact of the proposed Interstate Route 326 crossing of the Congaree River near Columbia, SC. The finite element model was assessed as a potential operational tool for analyzing complex highway crossings and other modifications of river flood...
Magnitude and chemical quality of base flow of Otter Creek, Tongue River, and Rosebud Creek, southeastern Montana, October 26-November 5, 1977
Roger W. Lee, Steven E. Slagle, James R. Stimson
1981, Open-File Report 80-1298
Hydrologic and chemical data were collected during base-flow conditions on three streams in southeastern Montana from October 26 to November 5, 1977, to characterize groundwater discharge. Maximum measured flow of Otter Creek, an interrupted stream, was 1.2 cubic feet per second. The water chemistry was dominated by sodium, magnesium, and...
Selected drill-stem-test data from the Northern Great Plains area of Montana
Gary W. Levings
1981, Open-File Report 81-326
Selected drill-stem-test data were collected for use in the hydrologic analysis of aquifers in the northern Great Plains area of Montana. To supplement existing data defining the potentiometric surface of various aquifers, shut-in pressures recorded during drill-stem tests of oil and gas test wells were used to calculate the altitude...
Selected hydrogeologic data from the Northern Great Plains area of Montana
Gary W. Levings
1981, Open-File Report 81-534
Selected hydrologic data have been used in a 4-year study of aquifers of Cenozoic and Mesozoic age in the northern Great Plains to define the hydrologic system and to generate hydrologic maps. Records of 6,754 wells and 188 springs are tabulated in the report. The well data include site location,...
Selected hydrogeologic data from the Judith Basin, central Montana
Julianne F. Levings, Kent A. Dodge
1981, Open-File Report 81-1015
Selected hydrogeologic data from the Judith basin, central Montana, have been compiled for use as the physical basis of a ground-water model prepared as part of a 4-year study of Cenozoic and Mesozoic aquifers of the northern Great Plains area of Montana. Records of Cenozoic and Mesozoic aquifers of the...
Road log and documentary photographs for 15 significant biostratigraphic sites in Miocene-Pliocene limestone, Kingshill Seaway, St. Croix, U.S. Virgin Islands
Barbara H. Lidz
1981, Open-File Report 81-1291
Detailed examination of planktonic Foraminifera from the type section of the Miocene Kingshill Limestone and from 14 other Miocene and lower Pliocene limestone exposures in the Kingshill Seaway of St. Croix ((at 17°44' N., long 64° 46' W.; fig. 1) has led to the first publication of an in-depth biostratigraphic...
