Modified level II streambed-scour analysis for structure I-74-70-4437 crossing Eagle Creek in Marion County, Indiana
B.A. Robinson, D. C. Voelker, R. L. Miller
1997, Open-File Report 97-308
Level II scour evaluations follow a process in which hydrologic, hydraulic, and sedimenttransport data are evaluated to calculate the depth of scour that may result when a given discharge is routed through a bridge opening. The results of the modified Level II analysis for structure 1-74-70-4437 on Interstate 74 crossing...
Geomorphic changes on the Mississippi River flood plain at Miller City, Illinois, as a result of the flood of 1993
Robert B. Jacobson, Kevin A. Oberg
1997, Circular 1120-J
During the 1993 floods on the upper Mississippi and Missouri rivers, the most dramatic changes to floodplains occurred at levee-break complexes where large discharges were concentrated through narrow breaks in levees. Scour and deposition associated with levee breaks adversely affected large areas of formerly productive bottomland. This case study of...
Stream Stability and Scour Assessments at Bridges in Massachusetts
Gene W. Parker, Lisa Bratton, David S. Armstrong
1997, Open-File Report 97-558
In 1989, the Federal Highway Administration mandated that every state establish a program to evaluate the vulnerability to floods of all bridges over water. The Massachusetts Highway Department entered into a cooperative effort with the U.S. Geological Survey to comply with this mandate. Geomorphic and hydraulic characteristics were collected and...
Estimates of bridge scour at two sites on the Virgin River, southeastern Nevada, using a sediment-transport model and historical geomorphic data
M.M. Hilmes, J. E. Vaill
1997, Water-Resources Investigations Report 97-4073
A bridge-scour study by the U.S. Geological Survey, in cooperation with the Nevada Department of Transportation, began in April 1996 to evaluate the Mesquite, Nevada, and Riverside, Nevada, bridges on the lower Virgin River using a sediment-transport model and historical geomorphic data. The BRIdge Stream Tube model for Alluvial River...
Changes in cross-section geometry and channel volume in two reaches of the Kankakee River in Illinois, 1959-94
Paul J. Terrio, John E. Nazimek
1997, Water-Resources Investigations Report 96-4261
The upstream reaches of the Kankakee River in Indiana have been channelized, straightened, and ditched to facilitate agriculture; the downstream reaches of the river in Illinois have not been so altered. Concerns about the adjustments of this low-gradient river in response to these disturbances have led to studies of sedimentation...
Method for rapid estimation of scour at highway bridges based on limited site data
S.R. Holnbeck, Charles Parrett
1997, Water-Resources Investigations Report 96-4310
Limited site data were used to develop a method for rapid estimation of scour at highway bridges. The estimates can be obtained in a matter of hours rather than several days as required by more-detailed methods. Such a method is important because scour assessments are needed to identify scour-critical...
Level II scour analysis for Bridge 8, (MANCTH00060008) on Town Highway 6, crossing Bourn Brook, Manchester, Vermont
Ronda L. Burns, Robert E. Hammond
1997, Open-File Report 97-813
This report provides the results of a detailed Level II analysis of scour potential at structure MANCTH00060008 on Town Highway 6 crossing Bourn Brook, Manchester, Vermont (figures 1–8). A Level II study is a basic engineering analysis of the site, including a quantitative analysis of stream stability and scour (U.S....
Evaluation of field and laboratory research on scour at bridge piers in the United States
David S. Mueller, J. Sterling Jones
1997, Conference Paper, Proceedings, Congress of the International Association of Hydraulic Research, IAHR
The Federal Highway Administration sponsored a laboratory research at Colorado State University and field data collection with the US Geological Survey, to evaluate the effects of bed material on the depth of scour. Correction factors are compared to include the effect of bed material in the HEC-18 equation. The HEC-18...
Initial results of high-resolution sea-floor mapping offshore of the New York - New Jersey metropolitan area using sidescan sonar
W. C. Schwab, M. A. Allison, W. Corso, L. L. Lotto, B. Butman, Marilyn R. Buchholtz ten Brink, J. F. Denny, W. W. Danforth, D.S. Foster
1997, Northeastern Geology and Environmental Sciences (19) 243-262
High-resolution seismic, sidescan-sonar, multibeam bathymetry, and sediment sampling techniques were used to map the surficial geology and shallow subbottom stratigraphy of a segment of the inner shelf and nearshore region of New York-New Jersey metropolitan area. Preliminary analyses of these data provide a sedimentologic framework for addressing a wide range...
Comparative behaviour and dietary effects in early life phases of American sturgeons
R. M. Ross, R. M. Bennett
1997, Fisheries Management and Ecology (4) 17-30
Experiments were conducted with the larvae and early juveniles of three species of sturgeon to determine effects of diet and development on swimming and foraging behaviour as well as depth distribution in 100-L aquaria. About 500 hatchlings were placed in each tank with two or three replicates of three or...
