Model Study of Center Hill Fuse Plug Spillway
Model tests of a fuseplug spillway mounted on the fixed crest of an embankment dam were conducted to develop a satisfactory design that would fail in a orderly fashion at a prescribed...

Laboratory Study of the Characteristics of Shallow Open Channel Flow Using Fiber-optic Laser Doppler Velocimetry
An experimental study was proposed to investigate the characteristics of shallow rain-impacted flow using a recirculating flume and an artificial rainfall simulator. The fibre-optic Laser...

Hydraulic Model Studies of Y-Branch
Hydraulic model studies were made for the Y-branch steel penstock located in a vertical bend. The model tests were performed for various modes of pumping and generating operation. The...

Confirmation of Seismic Safety at Stafford Dam
A critical aspect of the North Marin Water District's mission to maintain reliable water supply facilities and water service is periodic assessment and re-evaluation of the seismic safety...

Pier Scour on the South Saskatchewan River
A continuing program to measure river bed scour near bridge piers and abutments on the Alberta rivers has been on going for over thirty years. The objectives are to verify the existing...

Bridge Scour Prediction Methods Applicable to Streams in Pennsylvania
The Pennsylvania Department of Transportation, PennDOT, currently owns or maintains in excess of 28,000 bridges over 8 feet in length. The most common type of damage sustained by these...

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...

Large-Scale Embankment Overtopping Protection Tests
The U.S. Bureau of Reclamation (Reclamation), Colorado State University (CSU), and the Electric Power Research Institute (EPRI) have an ongoing cooperative research effort to determine...

Ballast Water Treatment Effluent Dispersion Studies
Treated tanker ballast water is discharged form Alyeska Pipeline Service Company's ballast water treatment facility through a multiport diffuser into Port Valdez, Alaska. The discharge...

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...

Using Geophysical Data to Assess Scour Development
The development of scour holes in the Connecticut River near the new Baldwin Bridge has been documented by comparing geophysical records collected before (1989), during (1990), and after...

Local Scour Measurements at Bridge Piers in Alberta
A summary of local pier scour data collected by Alberta Transportation and Utilities (AT & U) over the past 30 years is presented. Several methods used to gather this data are...

Reference Surfaces for Bridge Scour Depths
Depth of scour is measured as the vertical distance between scoured channel geometry and a measurement reference surface. A scour depth measurement can have a wide range depending on the...

Uncertainty of Bridge Scour Estimates
Pier scour is the erosion of a streambed in the vicinity of bridge pier foundations. In this paper, fuzzy regression is used to develop two pier scour models, one based on crisp laboratory...

Three-Dimensional Variable Resolution Hydrodynamic and Transport Modeling of the Chesapeake Bay System
This paper describes a domain decomposition methodology used in the application of the three-dimensional environmental fluid dynamics code, EFDC, to model hydrodynamics and transport in...

Field Examination of a Distribution System Water Quality Model
In the aftermath of the Safe Drinking Water Act (SDWA) of 1974, numerous models have been established to assess the quality of water and simulate its deterioration in distribution systems....

Evaluation of Historical Scour at Selected Stream Crossings in Indiana
Geophysical data were collected by means of ground-penetrating radar and tuned transducer systems to estimate the historical scour at ten bridges in Indiana. These geophysical data were...

Shale Scour at BNRR Yellowstone River Bridge, MT
Both the Burlington Northern Railroad and Montana Department of Transportation bridges across the Yellowstone river just south of Laurel, Montana, are founded on spread footings placed...

Analysis of Local Scour at Bridge Piers
Many studies have been performed on the cause and effects of local scour at bridge piers, and various prediction equations have been generated based on these studies. The general approach...

Hydraulic Performance of a Flexible Curtain Used for Selective Withdrawal ? A Physical Model and Prototype Comparison
Reclamation (U.S. Bureau of Reclamation) studied a 1:120 scale undistorted density stratified physical model to develop a lightweight flexible curtain barrier that would control the outflow...
