Monte Carlo Simulations of the Dynamic Response of Pile Groups
A study is presented on the effect of variations of relevant parameters within a pile group on the vertical dynamic response of the group. These parameters include the shear wave velocity...

Data Base of Seismic Body Wave Velocities and Geotechnical Properties
A data base of seismic velocities measured in soils and standard geotechnical engineering material properties has been established at the U.S. Army Engineer Waterways Experiment Station...

Hugo 1989 - The Performance of Structures in the Wind
The performance of buildings in the Carolinas during Hurricane Hugo, 21-22 September 1989, is reviewed. Wind speeds in most locations were below the design levels specified in the local...

Hydrodynamic Behavior of Cohesive Sediments in Turbulent Flow
To meet both engineering and basic research requirements, a series of experiments on the deposition of cohesive soil were conducted in an annular rotating fiberglass channel-ring system...

Dynamic Flushing of Pocket Marinas
The expanding demand for marina space combined with just concerns for the coastal environment has developed an urgent need for methods for evaluation of the flushing characteristics of...

Basic Physical Models in Sediment Transport
Basic particle dynamics and cellular automata micromodels of clastic sediments are described and applications are illustrated in the areas of aeolian saltation, bedload transport, size...

Review Notes on Cohesive Sediment Erosion
Comments are made on issues related to surface and mass erosion phenomena associated with cohesive sediment beds, and the entrainment of fluid mud. The rate process theory is recapped...

Shear Velocity and Eolian Sand Transport on a Barrier Island
Nearly 18 months of simultaneous measurements of atmospheric shear velocity, sand transport quantity, and beach erosion survey were made to investigate the rate of eolian sand transport...

Sand Movement by Wind?Optimising Predictive Power
The aim of the work reported here was to develop a model for the efficient utilisation of standard anemometer data for the prediction of potential sand movement. Accurate aeolian sand...

The Effect of Beach Vegetation on Aeolian Sand Transport
The effect of coastal vegetation on aeolian sand transport is examined through consideration of the governing aerodynamic processes. Local scale processes without the effect of ground...

The Vertical Structure of Cross-Shore Currents from Wind-Induced Setup
Most of the storm surge models presented in the literature are vertically averaged and calculate only the sea-surface elevation and mean flow. Whereas these models may be adequate for...

Infragravity Wave Motion in a Tidal Inlet
Infragravity waves (20

Analysis of Transport Processes on Ocean Disposal Mound
Disposal site 'F', an ocean disposal site for dredged sediments from Coos Bay, Oregon was designed to be a dispersive site. The site has not demonstrated high...

Effects of Hydroelectric Turbine Passage on Fish Early Life Stages
Turbine-passage mortality has been studied extensively for juveniles and adults of migratory fish species, but few studies have directly quantified mortality of fish eggs and larvae. An...

B.C. Hydro's Practice for Assessing the Foundations of Existing Dams on Rock
Since the early 1980's B.C. Hydro has carried out dam safety reviews which included 33 gravity and embankment dams founded on rock. The foundations include moderately jointed,...

Foundation Investigations of Concrete Dams
This paper discusses a series of foundation investigations conducted on concrete dams by Pacific Gas and Electric Company. The paper focuses on investigative techniques, equipment, appropriate...

Cone Penetration Testing: Cost Effective Soil Exploration
On reviewing the 1987 Part 12 Dam Safety Inspection Reports for the Wisconsin River Power Company's Petenwell and Castle Rock Dams, the Federal Energy Regulatory Commission...

Operational Procedures for Estimating Bottom Exchange Rates
After briefly reviewing the terminology of the various bottom and water column exchange fluxes, the body of this paper summarizes five possible procedures for establishing operational...

Turbulence and Reynolds Stress Distribution in a Natural River
Turbulence characteristics of ambient flow velocities and their comparison with those generated by the movement of barge traffic within the channel border area in a navigation waterway...

Hydrodynamics and Mass Transfer in a Jet-Agitated Vessel
Experiments of carbon dioxide absorption in water have been carried out in a turbulent vessel presenting a zero mean shear stress value at the gas-liquid interface. Liquid-phase turbulence...
