The TMA Wave-Energy Constraint and Cohesive Shore-Profile Shapes
A relation by Andreanov between wave-energy loss and nearshore slope, when combined with the TMA wave-energy constraint, is shown to closely approximate the classical Bruun/Dean shape....
Experimental Study of Undertow and Turbulence Intensity Under Irregular Waves in the Surf Zone
Experiments are performed in a two-dimensional wave tank with a sloping beach. Irregular waves are generated and the water particle velocity is measured in the surf zone with a laser Doppler...
Waves Propagating on an Adverse Jet
A laboratory investigated was conducted of the propagation of waves on an adverse three-dimensional jet. The problem which was simulated was the ebb-tide flow from a tidal inlet into a...
The Time Dependent Ray Method for Calculation of Wave Transformation on Water of Varying Depth and Current
This focuses on an aspect of the numerical calculation of wave refraction using the ray tracing or the semi-Lagrangian approach. the conventional ray method for steady state depth and...
Second Order Irregular?Wave Generation in Flumes - Computation of Transfer Functions by an Asymptotic Summation Method
Recently the theory for second order irregular-wave generation (including superharmonics as well as subharmonics) has been rederived for a variety of different types of wave board motion....
Kinematics of Wave Overtopping on Marine Structure
Kinematics of transient wave overtopping on coastal breakwaters has been studied both experimentally and numerically. For the laboratory experiments, solitary waves with moderate wave...
Optical Remote Sensing of Wave Surface Kinematics
The measurement of the directional properties of surface slopes, velocities and accelerations is difficult, even in the laboratory, under conditions of steep, random and short-crested...
Strategic Ship Routing Impacts of Temporal Coverage with Real-time Satellite Altimeter-Based Current Information
We investigate strategic ship routing impacts of temporal coverage with real-time satellite altimeter-based current information. We sample underlying daily `true' current patterns along...
The Tip Displacement of Drilled Shafts in Sands
The design load of large diameter drilled shafts is determined so that the settlements do not exceed the values associated with the ultimate and serviceability limit states. Based on the...
Assessing Roughing Filtration Design Variables
Rural communities are affected by the surface water treatment rule and are looking for inexpensive filtration options which are easy to operate and maintain. This paper evaluates roughing...
Formation and Propagation of Steep Waves: An Investigative Experimental Interpretation
From the end of the last century, many Authors have studied experimentally the formation and the propagation of steep waves on dry flume bottom. Up to the present time, however, some aspects...
Laboratory and Field Evaluation of Acoustic Velocity Meters
A project is currently underway to evaluate the performance of 27 acoustic flowmeters used at Hoover, Davis, and Parker Dams on the lower Colorado River. Field surveys and laboratory testing...
Mapping 2-D and 3-D Velocity Components in Circular Conduits Using an Electromagnetic Current Meter and a 5-Hole Pilot Probe
The techniques presented in this paper facilitate the visualization of the two-dimensional and three-dimensional flow fields at arbitrary sections in a conduit. They have been used to...
Velocity and Turbulence Measurement from the Illinois and Mississippi Rivers
This paper presents a data measurement program that was used for collecting the velocity data associated with barge-tow traffic on the Illinois and Mississippi Rivers and includes a discussion...
Velocity Measurements by the One-Orange Method
Application of the most sophisticated instrumentation - so called state-of-the-art equipment - is not always necessary nor even desirable for measurement of mean velocities in verticals,...
On Measurements of Particle Spinning Motion
Investigation of particle saltation motion is crucial to the development of the theory of bed load transport. Due to the combination effects of the bed roughness and the velocity gradient,...
Hot-Film Response in Three-Dimensional Highly Turbulent Flows
A methodology is described for accurate turbulence measurements with hot film or hot wires even at turbulent intensities as high as 100%. The assumptions involved and the approximations...
Response of Velocity and Turbulence to Abrupt Changes from Smooth to Rough Beds in Open-channel Flows
Response of velocity distribution and turbulence characteristics to abrupt changes of bed roughness have been investigated experimentally with two-component laser Doppler anemometer (LDA)....
Optical Methods for Sediment-Laden Flows
A method of distinguishing between the signals from the liquid-seed particles and sediment particles, while using LDV in sediment-laden flows, is described. The validity of the method...
Estimation of Mean Velocity for Flow Under Ice Cover
Methods of estimating mean velocity in a vertical from point velocity measurements are compared for an ice-covered channel. The comparison is based on velocity profiles obtained from a...
