Mobile-Bed Physical Model Tests for the 1992 Olympic Harbour
The undistorted physical model is described which allowed the measurement of the wave induced velocity field along the main breakwater, and also in Somorrostro Beach (Barcelona). The current...

Radiocolloid Transport in Saturated and Unsaturated Fractures
Studies have shown that radionuclides and toxic materials can attach to colloidal particles in groundwater or are themselves colloids. Since these contaminated particles can migrate several...

Correlation of Hydraulic Conductivity and Sonic Velocity in Water-Saturated Tuff
A laboratory study was conducted to investigate the correlation of hydraulic and sonic properties of water-saturated tuff. The hydraulic test used a new rock block testing machine, which...

Nondestructive Testing Using Borehole and Surface Seismic Techniques to Evaluate Rock Mass Damage Zones
A suite of seismic tests was performed at the U12g tunnel at the Nevada Test Site. The methods include borehole (crosshole and downhole) and surface (Rayleigh wave and refraction) tests....

An Expert System for the Planning and Design of Flood Control Channels
The planning and design of flood control channels often calls for the evaluation of a unique set of physical conditions which do not lend themselves to standard designs. Consequently,...

A Comparison of Accuracies of Steady Water Surface Profiles
The author compares the effect of varying boundary conditions and cross sectional spacing on one dimensional steady water surface profiles. Six streams are modeled using both the 10 and...

On the Transformation of Wave Spectra by Currents and Bathymetry
Application of the conservation principle for action spectral density along rays, frequently described in literature, is not sufficient to specify the refracted wave spectrum. In order...

A Turbulence Model for Transverse Mixing in Rivers
A two length-scale turbulence model is developed to simulate transverse mixing prosesses in rivers. The dispersion of the effluent from the MUC (Montreal Urban Community) sewage treatment...

The Moving Contact Line
The flow field around the moving contact line, generated by an impulsive, horizontal motion of a vertical plate, is studied numerically. The two-dimensional, unsteady Navier-Stokes equations,...

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...

Numerical Modeling of Storm-Induced Beach Erosion, Folly Beach, South Carolina, Beach Fill Alternatives
The U.S. Army Engineer District, Charleston (SAC), is developing a National Economic Development (NED) Plan for providing northeaster and hurricane storm protection for the municipality...

Long Term Assessment of Beach Nourishment Project Performance
Long-term data on profile response, sediment distribution and wave information have been collected and analyzed for the Indialantic/Melbourne Beach beach nourishment project in order to...

Effect of Shell on Beach Performance: Examples from the West-Central Coast of Florida
Time-series analysis of beach profiles and sediment analysis along the Pinellas County coast of Florida over a 2-yr. period shows that shell abundance has an influence on beach performance....

Marsh Erosion by Wave Action
This paper summarizes an analysis of salt marsh shoreline erosion, wind velocities and wave energy in Corte Madera Bay during an abnormally calm period in 1989. Winds during the study...

Beach and Cliff Erosion Processes at Solana Beach, California, 1984-1990
Observations of back beach elevation changes, profiles and cliff erosion over a 7-year period from 1984-1990 provide a detailed local view of these processes and rates at a typical Southern...

Saline Intrusion in Marine Effluent Outfalls
The paper presents an experimental investigation of saline intrusion in long sea outfalls. This intrusion is caused by the influx of sea water that may occur during periods of low discharge,...

Infragravity Driven Suspended Sediment Transport in the Swash, Inner and Outer-Surf Zone
Nearbed suspended sediment concentration and velocity measurements from 3 field sites in the mid-outer surf zone (low energy), inner surf zone (high energy) and swash (high energy) are...

Monitoring the Response of the Inter-Tidal Beach Profile to Tidal and Wave Forcing
The need for sets of beach profile and wave data of one year duration, sampled at sub-weekly intervals, is well recognised in the literature. Some of the initial data from a macro-tidal...

Sediment Transport by Strong Wave-Plus-Current Flows
A prediction formula is derived for the suspended sediment transport rate in coastal regions when the current speed and/or wave orbital velocity is large. It is based on generalised forms...
