Contraction scour at a bridge over the Iowa River
Edward E. Fischer
1994, Conference Paper, Proceedings - National Conference on Hydraulic Engineering
Flooding of the Iowa River during July and August 1993 caused extensive contraction scour at the State Highway 99 bridge over the Iowa River at Wapello, Iowa. At least 3.3 m of piling under the footing of the second pier from the right (west) abutment were exposed. The scoured streambed...

Strong ground motion generated by the Loma Prieta, Calif., earthquake (MS~7.1) of October 17, 1989, resulted in at least 63 deaths, more than 3,757 injuries, and damage estimated to exceed $5.9 billion. Strong ground motion severely damaged critical lifelines (freeway overpasses, bridges, and pipelines), caused severe damage to poorly constructed...
Prediction of structural response to large earthquakes by using recordings from smaller earthquakes
Erdal Safak
1994, Conference Paper, Structures Congress XII
The feasibility of predicting structural response to large earthquakes by using recorded responses from collocated smaller earthquakes is investigated. Records from large earthquakes can be approximated as linear combinations of records from smaller earthquakes. Two methods are introduced to predict structural response to a large earthquake by using the recorded...
National Spatial Data Infrastructure and its usefulness to the dredging community

McNair Clark E., editor(s)
1994, Conference Paper, International Conference on Dredging and Dredged Material Placement
The solution to understanding the dredging impacts is the type of scenario that lends itself to new approaches to understanding interrelationships between multiple variables within a dynamic environment. New data are becoming available to allow the examination of the consequences of dredging in a manner not done before. Efforts have...

Simulating effects of highway embankments on estuarine circulation
Jonathan K. Lee, Raymond W. Schaffranek, Robert A. Baltzer
1994, Journal of Waterway, Port, Coastal and Ocean Engineering (120) 199-218
A two‐dimensional, depth‐averaged, finite‐difference, numerical model was used to simulate tidal circulation and mass transport in the Port Royal Sound, South Carolina, estuarine system. The purpose of the study was to demonstrate the utility of the Surface‐Water, Integrated, Flow and Transport model (SWIFT2D) for evaluating changes in circulation patterns and...
Geomorphic response to channel modifications of Skuna River at the State Highway 9 crossing at Bruce, Calhoun County, Mississippi
K.V. Wilson Jr., D.P. Turnipseed
1994, Water-Resources Investigations Report 94-4000
Skuna River at State Highway 9 at Bruce, Calhoun County, Mississippi, has geomorphically responded to channel modifications by lowering of the channel bed through degradation, which heightened and steepened channel banks and induced widening. Skuna River Canal (Skuna River) has typically degraded about 16.5 feet and widened about 150 feet...

Flood discharges and hydraulics near the mouths of Wolf Creek, Craig Branch, Manns Creek, Dunloup Creek, and Mill Creek in the New River Gorge National River, West Virginia
J.B. Wiley
1994, Water-Resources Investigations Report 93-4133
The U.S. Geological Survey, in cooperation with the National Park Service, studied the frequency and magnitude of flooding near the mouths of five tributaries to the New River in the New River Gorge National River. The 100-year peak discharge at each tributary was determined from regional frequency equations. The 100-year...
Historical and potential scour around bridge piers and abutments of selected stream crossings in Indiana
D. S. Mueller, R. L. Miller, J.T. Wilson
1994, Water-Resources Investigations Report 93-4066
Historical scour data were collected by means of geophysical techniques and used to evaluate the scour-computation procedures recommended by the U.S. Federal Highway Administration and 12 other pub- lished pier-scour equations. Geophysical data were collected at 10 bridges in Indiana. For this evaluation it was assumed that the historical scour...
Effects of ion exchange on stream solute fluxes in a basin receiving highway deicing salts
J. B. Shanley
1994, Journal of Environmental Quality (23) 977-986
At Fever Brook, a 1260-ha forested basin in central Massachusetts, highway deicing salt application increased the solute flux in streamflow by 120% above background flux (equivalent basis) during a 2-yr period. Attempts to isolate the nonsalt component of stream solute fluxes have commonly subtracted salt contributions...
Lateral movement and stability of channel banks near four highway crossings in southwestern Mississippi
D. Phil Turnipseed
1994, Water-Resources Investigations Report 94-4035
Channel meandering in alluvial streams has caused localized channel instability that has resulted in bridge failure and loss of human life in Mississippi. The U.S. Geological Survey, in coopera- tion with the Mississippi Department of Transpor- tation, conducted a study to develop a better methodology for defining and estimating channel...

Application of electromagnetic logging to contamination investigations in glacial sand-and-gravel aquifers
John Williams, Wayne W. Lapham, Thomas H. Barringer
1993, Groundwater Monitoring & Remediation (13) 129-138
Electromagnetic (EM) logging provides an efficient method for high‐resolution, vertical delineation of electrically conductive contamination in glacial sand‐and‐gravel aquifers. LM. gamma, and lithologic logs and specific conductance data from sand‐and‐gravel aquifers at five sites in the northeastern United States were analyzed to define the relation of KM conductivity...
