Comparing Results of Wave Data from Two Recorders
In this paper two sets of wave measurements made in the same region using a pressure transducer and a wave rider bouy are compared. The same methods of analysis were applied to both the...

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...

A Program to Acquire Deep Ocean Tsunami Measurements in the North Pacific
Deep ocean tsunami measurements are needed to provide open ocean boundary conditions for testing numerical models in hindcast studies, and for improving our understanding of tsunami generation...

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...

Assessment of Pore Fluid Effects Using Flexible Wall and Consolidation Permeameters
Hydraulic conductivity tests were conducted on compacted soil specimens prepared at activities of 0. 36, 0. 60, 1. 00 and 1. 39 at a fine fraction of 25 percent. Na-montmorillonite, Georgia...

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...

The Use of Cone Penetration Testing for Evaluation of Waste Disposal Alternatives
Geotechnical information derived from cone penetration testing (CPT) has been found to give increased accuracy in the siting of waste disposal facilities and in the design of remedial...

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...

The NOS Experience in Real-Time Measurements of Tidal Currents
NOAA'S National Ocean Service (NOS) uses the term RADS, Remote Acoustic Doppler Sensing, for a new class of oceanographic instruments that uses acoustic backscatter to probe...

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...
