The Bridge StreamTube Model for Alluvial River Simulation (BRI-STARS) is a semi-two-dimensional model capable of computing alluvial scour/deposition through subcritical, supercritical,...

Practical Comparison of One-Dimensional and Two-Dimensional Hydraulic Analyses for Bridge Scour
The Kentucky Transportation Cabinet, Department of Highways is working with the Indiana Department of Transportation and the Federal Highway Administration to plan, design, and construct...

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...

Debris Flow Initiation and Termination in a Gully
A comprehensive simulation model predicting the debris-flow discharge hydrograph, solids concentration in it and the process of variation of the channel due to vertical as well as lateral...

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...

Methods for Prediction of Maximum Scour at Coastal Structures
The most common coast scour-related problems are toe scour at rubble mound structures and vertical seawalls, and scour at the base of piles and horizontal pipelines. Existing scour prediction...

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...

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...

Structural and Non-Structural Debris-Flow Countermeasures
Debris-flow can potentially occur for almost any torrents whose gradient is steeper than a given critical value and the frequency at which the debris-flow occurs depends on geological...

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,...

Hydrologic Design: Extending Traditional Methods
A review of traditional hydrologic design shows that it is inadequate. The continued adaptation of manual techniques into computer software without a major change in fundamental assumptions...

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...

Large-Scale Embankment Overtopping Protection Tests
