Model Study of Local Scour Downstream Bridge Piers
A deep scour hole downstream of a large circular pier has been developed at Imbaba bridge, which is considered one of the major bridges across the Nile River in Cairo, Egypt. At that location...
Effect of Fenders on Local Pier Scour
Physical model experiments were performed in the Hydraulics and Sediment Research Institute, Delta Barrage, Egypt, to determine the effect of fenders on the scour depth around circular...
Hydraulic Modeling and Mapping of Mud and Debris Flows
The prediction of hyperconcentrated sediment flows on alluvial fans was advanced through the development of a two-dimensional, finite difference flood routing model FLO-2D. The model simulates...
Application of Environmental Regulations on Design of Hydraulic Structures for Open Cooling Water System
Design of intake and discharge structures for an open cooling water system for a thermal power plant requires that the design of hydraulic structures meets the federal, state, and local...
Design of a Curved Baffle Energy Dissipation Structure
A curved baffle energy dissipation structure was designed and constructed based on the results of hydraulic and analytical models. Field tests of the prototype demonstrate close comparison...
Scour at a Bridge Over the Weldon River, Iowa
Contraction scour at the State Highway 2 bridge over the Weldon River in south-central Iowa was caused by a flood of record proportions on September 14 and 15, 1992. The peak discharge...
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...
Evaluation of Hydraulic Structure Reliability Considering Uncertainties in Hydrologic Models
Uncertainties in a hydrologic model give rise to uncertainty in model outputs which, in turn, can be used for reliability-based design and /or evaluation of hydraulic structures. This...
Analyzing Uncertainty of IUH of Nash
Uncertainties in hydrologic modeling are the primary factors affecting the reliability of hydraulic structures. Among various hydrologic rainfall-runoff models for engineering applications,...
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...
