Brief Summary of National Bridge Scour Data Base
This paper briefly summarizes more than 470 measurements of local channel scour at bridge piers from 58 sites in 14 States. Relations between local scour and selected deterministic parameters...

Ultimate Depth of Scour Around Bridge Piers
A design equation for estimating ultimate depth of local scour at bridge piers has been proposed which is based upon the envelope curves drawn to published field data covering a wide range...

Kent, Edward
In order to perform conservative scour analyses for coastal bridge sites it is necessary to develop realistic hydraulic simulations which provide worst case estimates of depth and velocity....

Bridge Pier Scour Equations - An Assessment
A comparative assessment of various bridge pier scour equations has been reported on the basis of analyzing a set of published prototype data from Indian rivers and other countries covering...

Hydrodynamic Modeling of San Diego Bay
A two-dimensional vertically-averaged finite element model was adapted to study the hydrodynamics of San Diego Bay. The hydrodynamic model was interfaced with pre- and post-processors...

Spectral and Parametric Wave Models of Lake Erie
The GLERL-Donelan parametric wave model and the SHALWV spectral wave model are presently being used as modules of the Great Lakes Forecasting System in order to determine which best fits...

Short-Term Forecasts for Lake Erie
Short-term forecasts for Lake Erie were generated by coupling a mesoscale atmospheric prediction system with a lake forecast system. The modeling systems used were The Pennsylvania State...

West Columbus, OH LPP Gate Closure Analysis - A Study of the Requirements for Multiple Closures
Providing flood protection by levees and/or floodwalls often requires the use of temporary closures, in lieu of the more expensive relocation of highways and railroads, in order to maintain...

Hydraulics and Sediment Transport Processes in a Pool-Riffle Rocky Mountain Stream
Sediment transport processes related to varying channel-bed morphology were investigated from April to November, 1993 along a 1 km pool-riffle and step-pool reach of North Saint Vrain...

Analysis of Selected Prototype Wave and Runup Data
An investigation of wave runup using video camera technology at Duck, N.C. is discussed. Results are provided from a subset of the runup experiment and wave runup level probability density...

Sheet Flow Resistance of Asphaltic Pavements
A statistical study has been conducted by the authors using 400 points of experimental data taken in the 1970's at Texas A&M for sheet flow runoff during artificial rainfall on...

Theoretical study of unstable waves in the rapids of the river
This paper examines how the velocity distribution in free-surface flow affects the kinematic and dynamic velocities of disturbance waves on hillslopes or in high-gradient rivers, thereby...

Numerical Analysis of High Velocity Flow with Zero-Depth Line and Oblique Shock Wave in Steep Open-Channels
This paper deals with the numerical analysis of 2D steady high velocity flows with the zero - depth line and the oblique shock wave in steep open channels by means of the method of characteristics....

Considerations in 2-D Modeling of Hydraulically Steep Flow
Simplifications in the equations used to describe shallow water flow lead to some difficulties in modeling supercritical flow. The hydrostatic assumption produces two significant differences...

Ocean Wave Measurement and Analysis
This proceedings, Ocean Wave Measurement and Analysis, consists of papers presented at the Second International Symposium on Ocean Wave Measurement...

Alternatives for Overtopping Protection of Dams
Prepared by the Task Committee on Overtopping Protection of the Hydraulics Division of ASCE. This report summarizes the results of an inventory and...

Bearing Capacity of Soils
Technical Engineering and Design Guides, as adapted from the U.S. Army Corps of Engineers, No. 7 This U.S. Army Corps of Engineers engineering manual...

Coastal Dynamics `94
During the past decade, numerical models of coastal dynamics have provided far more information than could be validated with field and laboratory measurements. Lack of data has restricted...

Reconstruction of the West Breakwater at Port Sines, Portugal
This volume, Reconstruction of the West Breakwater at Port Sines, Portugal, is a collection of papers presented at a seminar held at Sines,...

Factors Controlling Strong Ground Motion and Their Associated Uncertainties
Of special interest in strong ground motion modeling is a quantification of the degree of influence specific physical parameters have on the computed motions. Associated with the model...
