Riparian-vegetation controls on the spatial pattern of stream-channel instability, Little Piney Creek, Missouri
Robert B. Jacobson, Aaron L. Pugh
1998, Water Supply Paper 2494
The role of riparian vegetation is assessed quantitatively by using a five-decade record of valley bottom vegetation and channel dynamics developed from historical aerial photography. A 12-kilometer reach of a typical Ozarks stream was mapped using aerial photographs from 1938, 1948, 1955, 1965, 1976, and 1989; maps were then analyzed...

C. W. Schalk
1998, Water-Resources Investigations Report 98-4108
Pesticides have not been found frequently in the ground waters of Ohio even though large amounts of agricultural pesticides are applied to fields in Ohio every year. State regulators, including representatives from Ohio Environmental Protection Agency and Departments of Agriculture, Health, and Natural Resources, are striving to limit the presence...
Methyl tert-butyl ether (MTBE) and other volatile organic compounds in lakes in Byram Township, Sussex County, New Jersey, summer 1998
Arthur L. Baehr, Otto S. Zapecza
1998, Water-Resources Investigations Report 98-4264
Water samples were collected from four lakes in Byram Township, Sussex County, N.J., in the summer of 1998 as part of an investigation of the occurrence of volatile organic compounds (VOCs) in domestic wells of lakeside communities. Cranberry Lake and Lake Lackawanna are surrounded by densely populated communities where the...
Aggregates from natural and recycled sources; economic assessments for construction applications; a materials flow study
David R. Wilburn, Thomas G. Goonan
1998, Circular 1176
Increased amounts of recycled materials are being used to supplement natural aggregates (derived from crushed stone, sand and gravel) in road construction. An understanding of the economics and factors affecting the level of aggregates recycling is useful in estimating the potential for recycling and in assessing the total supply picture...
Depth-duration frequency of precipitation for Texas
William H. Asquith
1998, Water-Resources Investigations Report 98-4044
The U.S. Geological Survey, in cooperation with the Texas Department of Transportation, conducted a study of the depth-duration frequency of precipitation for Texas. Depth-duration frequency is an estimate of the depth of precipitation for a specified duration and frequency or recurrence interval. For this report, precipitation durations of 15, 30,...

Recharge-area delineation and hydrology, McCraken Springs, Fort Knox Military Reservation, Meade County, Kentucky
Charles J. Taylor, Gregory K. McCombs
1998, Water-Resources Investigations Report 98-4196
McCraken Springs, consisting of three perennial springs - Main, Bat Cave, and Rocky Springs—and several intermittent springs, are used as a source of public water by the Fort Knox Military Reservation in Meade County, Ky. The water supply provided by McCraken Springs is potentially vulnerable to natural and induced stresses...

Simulation of ground-water flow, Dayton area, southwestern Ohio
D.H. Dumouchelle
1998, Water-Resources Investigations Report 98-4048
A numerical model was used simulate the regional ground-water-flow system in the Dayton area in southwestern Ohio. Ground water is the primary source of drinking water for the Dayton area. The aquifer consists of glacial sands and gravels in a buried bedrock valley. The shale bed rock in the area...
