Waste Disposal in Coastal Waters
The increasing concentration of population and industry on coastal areas, is making greater demands for coastal disposal. However, the coastal waters are also used for recreation, and...
Quantification of Net Shore-Drift Rates in Puget Sound and the Strait of Juan de Fuca
The objective in this study was to determine the annual rate of net shore-drift at selected sites within Puget Sound and the Strait of Juan de Fuca. These sites were selected based on...
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...
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...
Pressure Fluctuations on the Floow of Hydraulic Jumps
This paper presents the results of an experimental investigation regarding the variation of r. m. s. value of pressure fluctuations on the floor of free and forced hydraulic jumps formed...
Plume Underflow Interaction in Natural Enclosures
A preliminary investigation into the feasibility of using a hot-water plume to intercept and entrain a cold underflow is presented. The investigation involved an adaptation of existing...
Open Channel Flow Resistance in Horseshoe Conduits
An experimental study of open channel flow resistance in horseshoe-shaped conduits is reported. The friction factor is shown to increase approximately 20 percent in comparison to values...
Experiments on Culvert Flow
Laboratory experiments are described which were performed on small-scale models of smooth circular culverts of length-to-diameter ratio varying between 13 and 52, and longitudinal downward...
Flume Measures Ultra-Wide Discharge Range
Advances in mathematical modeling in the mid-1970's have led to accurate modeling of discharge and energy loss characteristics of long-throated flumes. A complex long-throated...
