Comparison of Two Methods of Screening Bridges for Scour
Scour evaluations were performed for large numbers of bridges in two separate studies in New York and New Jersey. The two studies used different screening methods for identifying high-priority...

Case Studies of Bridge Scour in Western New York
As part of the New York State Thruway Authority's bridge hydrologic/hydraulic evaluation program, 63 structures over 42 stream crossings in western New York were assessed for scour potential...

Risk Analysis of River Bridge Failure
The proposed procedure to determine the risk of river bridge failure is based on observations and analysis of river bridge failure data of more than 300 U.S. bridges, 180 South African...

Comparison of Theoretical and Historical Scour
As part of scour assessments at approximately 120 stream crossings on the New York State Thruway, subsurface investigations were performed at all structures and, in some instances, locations...

Calibration of Manning's Roughness for a River Reach
The Albuquerque Projects Office of the U.S. Bureau of Reclamation collected water surface elevations for measured discharges for the Rio Grande and many of its tributaries to try to obtain...

Estimating Bridge Scour in New York from Historical U.S. Geological Survey Streamflow Measurements
Historical streamflow measurements by the U.S. Geological Survey an bridge-inspection reports by the New York State Department of Transportation are being used to estimate scour at 31...

Relation of Local Scour to Hydraulic Properties at Selected Bridges in New York
Hydraulic properties, bridge geometry, and basin characteristics at 31 bridges in New York are being investigated to identify factors that affect local scour. Streambed elevations measured...

Scour Inspection Using Ground Penetrating Radar
This paper examines the capabilities of Ground Penetrating Radar (GPR) for river bed scour inspection based on a study carried out by Clarkson University, Potsdam, New York in association...

Importance of Hydraulic-Model Uncertainty in Flood-Stage Estimation
The delineation of the regulatory floodplain and determination of the respective flood stage is subject to hydraulic-model uncertainty in transforming the design discharge into a flood...

Evaluation of an Existing Scour Hole at the Castleton Bridge, a Tidal Crossing
Several fathometric surveys conducted in recent years showed a large depression or scour hole on the downstream southeast corner of the central pier of the Castleton Bridge over the Hudson...

New York Bight Three-Dimensional Water Quality Model
The numerical modeling technology developed for Chesapeake Bay was applied to the Middle Atlantic Bight extending 550 km form Cape May, NJ, northeasterly to Nantucket Island, MA, and extending...

New Road Safety Initiatives in New Zealand
A considerable number of initiatives have been taken in New Zealand recently to keep pressure on the downward trend in road crashes and casualties. These have included government legislation...

Coordination of ISTEA?1991 Management Systems
Following the successful development and implementation of pavement management concepts, the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) contains the provision that...

The Application of 3 Dimensional Geographic Information Systems in Geotechnical Earthquake Engineering
The requirements and needs of Geographical Information Systems (GIS) in geotechnical earthquake engineering are described, and the use of such system in New Zealand is discussed. We have...
