Foredune Management on a Developed Shoreline: Nedonna Beach, Oregon
Nedonna Beach and Rockaway Beach are adjoining oceanfront communities with foredunes that were developed before state policies went into effect. The foredunes in these two communities...
Numerical Solutions for Problems Related to Nearshore Morphology?!
In the development of numerical models of nearshore morphology various steps can be envisaged: 1. initial models: the initial bottom topography remains unchanged; spatial variations in...
Tractive Flows Adjacent to Site for Submarine Sewage Pipeline
Twin 3200 m long submarine sewage pipelines for the city of Vancouver are being placed across the outer tidal flats and upper slope of the Fraser River delta to a water depth of 107 m....
Coriolis and Our Land-Sea Environments
The characterizations of the Coriolis Acceleration Vector with water pile-up and circulating currents, which produce shoreline erosion or accretion were presented at the Coastal Zone 85...
Practical Application of Acoustic Doppler Profilers
This paper discusses the advantages and limitations of the acoustic Doppler current profiler (ADCP), and it reviews some of the experience gained to date with the ADCP relevant to currents...
Drift of Floatable Materials in Puget Sound
Cost-effective methods for predicting the fate of surface borne (floatable) materials and contaminants have been applied successfully within Puget Sound. Several preferred areas for the...
Hydrogeologic Investigations at a Superfund Site in Wisconsin
An estimated 10,000 drums of volatile organic wastes from a nearby manufacturing plant were dumped at a landfill site in southern Wisconsin. Chemicals released from these drums have contaminated...
Use of Vibration Measurements in Structural Evaluation
Over the past decade the capabilities for vibration measurements and analysis have advanced significantly. It is now a routine procedure to be able to measure natural frequencies of structures...
Computer Aided Simulation of Fluid-Structure Interaction Problems
The papers included in this book represent state-of-the-art developments in and applications of computer aided simulation of fluid-structure interaction problems in both the terrestrial...
Engineering Aspects of Soil Erosion, Dispersive Clays and Loess
This collection of papers deals with selected engineering aspects of soil erosion, dispersive clays and loess. Two types of erosion are considered?surface and subsurface (piping)?with...
Dynamic Response of Pile Foundations?Experiment, Analysis and Observation
In recent years, a considerable amount of attention has been paid to the dynamic response behavior of pile foundations. However, mainly because of difficulties in conducting tests and/or...
The Mexico Earthquakes?1985
Factors Involved and Lessons Learned
This publication reports initial results of study of the 1985 Mexico earthquake, one year after the event. The findings present sufficient depth of analysis to provide an understanding...
Water Jets: Concrete Yes, Tunneling Maybe
High pressure water jets are demolishing concrete from bridge and parking decks, faster and at lower cost than by traditional means. The technique is fast becoming an acceptable option....
Long Crested Weirs
A method has been developed to integrate and evaluate the head relationship between canal weirs and turnouts. The objective is to minimize flow variations through the turnout and at the...
Philosophy and Implementation of Gate Stroking
The purpose of this paper is to examine one control method - gate stroking - the philosophy which would lead to its selection and an example of its implementation. Gate stroking provides...
Physical Modeling of Contracted Flow
Experiments on steady flow over uniform grass roughness through centered single-opening contractions were conducted in the Flood Plain Simulation Facility at the U. S. Geological Survey's...
Simultaneous Releases from a Stratified Reservoir
The concept of simultaneously, selectively withdrawing water from multiple levels in a thermally, and therefore density, stratified reservoir is presented and its usefulness discussed....
Density Currents in Clarifiers
This paper discusses internal flow regimes associated with the density currents due to diurnal heat loading. The reported studies were carried out with the aid of physical models....
Riprap Stability on Channel Slide Slopes
The stability of riprap placed on a sloping bank is decreased because one component of gravity tends to displace the rock down the slope. Results of riprap stability tests on sloping banks...
Estimating Average Velocity in Cobble-Bed Channels
A data set obtained from natural channels having D//5//0 less than 64 mm and d/D//5//0 in the range of 3 to 20 is used as a basis for testing equations proposed by Limerinos, Thompson...
