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...
Suspended Sediment Load at Three Time Scales
Suspended sediment loads were examined at the three time scales of time-series-averaged, wave-by-wave and instantaneous during the wave cycle. Field measurements recorded on a natural...
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
Regional Sediment Transport in the Coastal Boundary Layer of the Central Alaskan Beaufort Sea
The characteristics of regional sediment transport in the Central Alaskan Beaufort Sea Coastal Ocean are defined by sources, marine sediment dynamics, and areas of net sedimentation. These...
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...
Three Dimensional Modeling of Concrete Dams with Cracks Using Boundary Element Methods
Determining uplift pressure distributions in cracks in a concrete dam requires coupling between crack hydraulics and the stresses and displacements occurring in the rock and the concrete...
Slug Test: Double-Porosity, Linear Boundary, and Variable Storage Effects
The intention of this paper is to focus on three aspects of the slug test that are not as familiar as the main analysis techniques: the effects of double-porosity formations, the effects...
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...
Measurement of Air Entrained Flow Properties
The paper discusses conventional methods used in the field to measure bubble size, air concentration, intermittency, and velocity of air entrained flows in chutes....
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...
Properties of Small-Scale Waves in Sheared Gas-Liquid Flows
Small wind-generated waves are examined theoretically and experimentally in a small laboratory flow system, at conditions close to neutral stability in an attempt to better characterize...
