INTRODUCTION: In the U.S. Geological Survey's (USGS) 1995 National Assessment of United States oil and gas resources (Gautier and others, 1995), the Appalachian basin was estimated to have, at a mean value, about 61 trillion cubic feet (TCF) of recoverable gas in sandstone and shale reservoirs of Paleozoic age. Approximately...
Water-Quality Assessment of the Trinity River Basin, Texas - Pesticides in a Coastal Prairie Agricultural Area, 1994-95
M.F. Brown
1996, Open-File Report 96-124
Agriculture is a major land use in the coastal prairie area located in the southern part of the Trinity River Basin. Crops grown in the area include rice, sorghum, and soybeans. Pesticide- use estimates for the area show that compounds with the highest use are the herbicides: molinate, propanil, thiobencarb,...

Flood-frequency and detention-storage characteristics of Bear Branch watershed, Murfreesboro, Tennessee
G.S. Outlaw
1996, Water-Resources Investigations Report 96-4005
The U.S. Geological Survey's Distributed Routing Rainfall-Runoff Model [DR3M] was applied to a 2.27-square-mile portion of Bear Branch watershed at Murfreesboro, Tennessee, to demonstrate the application of this model to small urban watersheds in central Tennessee. Kinematic wave theory was used to route excess rainfall overland and through a branched...
Feasibility of using acoustic velocity meters for estimating highly organic suspended-solids concentrations in streams
Eduardo Patino
1996, Open-File Report 96-137
A field experiment was conducted at the Levee 4 canal site below control structure G-88 in the Everglades agricultural area in northwestern Broward County, Florida, to study the relation of acoustic attenuation to suspended-solids concentrations. Acoustic velocity meter and temperature data were obtained with concurrent water samples analyzed for suspended-solids...
Geohydrology of the shallow aquifers in the Denver metropolitan area, Colorado
Stanley G. Robson
1996, Hydrologic Atlas 736
The Denver metropolitan area is underlain by shallow layers of water-bearing sediments (aquifers) consisting of unconsolidated gravel, sand, silt, and clay. The depth to water in these aquifers is less than 20 feet in much of the area, and the aquifers provide a ready source of water to numerous shallow,...
