Using Sediment-Threshold Theories in Waves and Currents
Fundamentally different threshold-of-motion theories were applied to sand transport in two different coastal environments. Several recommendations for threshold application were reached....

Compendium of International Ocean Energy Activities
This Compendium of International Ocean Energy Activites has been designed as a resource directory of ocean energy projects in the United States...

Routing a Cold Water Release Through TVA Reservoirs to Control Intake Temperatures at a Power Plant
A volume of cold water was routed some 160 miles through the TVA reservoir system to keep a nuclear plant intake temperature within safety limits. Mathematical modeling of the operation...

Effects on Reservoir Water Quality Caused by Changes in Inflow Plume Hydrodynamics
In this paper, the effects of environmental changes on the hydrodynamic behavior of the Las Vegas Wash inflow into Lake Mead are discussed from the view-point of water quality. It is hypothesized...

Coastal Zone '89
Coastal Zone '89 is the sixth in a series of multidisciplinary meetings on comprehensive coastal and ocean management. The papers included in this publication review technical...

Intrusion of Turbid Water into a Two-Layer Stratified Environment
The horizontal intrusion of a turbid water with some intermediate density spreading on the interface of a two-layered homogeneous body of water is investigated. The study is directed towards...

Sedimentology of a Composite Inner-Shelf Sand Body Resulting from the Resuspension of Nearshore Sediment by Episodic, Storm-Generated Currents: Oceanside, California

RCC Pavement Construction and Quality Control
In October 1986 a 16,500 sq yd (14,300 sq m) roller-compacted concrete (RCC) pavement tank hardstand, the first of its kind in Europe, was built for the U. S. Army at Harvey Barracks in...

Initiation of Density Currents in Diverging Channels: Comparison of Field and Laboratory Data
The transition from free surface channel flow to a submerged density current has been investigated in the laboratory. A set of field data has been collected at a wastewater effluent site....

An Alternate Theory of Density Current Propagation
Density current propagation has been previously analyzed by employing a one-dimensional momentum balance in a frame of reference moving with the density current head. Experimental data...

Interfacial Instabilities Associated with Density Currents
Three-dimensional behavior of density currents flowing down a sloping surface has been analytically and experimentally investigated. Attention has been given to the presence of interfacial...

Entrainment of Bed Sediment by Density Underflows
The erosion caused by a density-driven underflow has been studied experimentally. The observations indicate that a strong density current can entrain substantial amounts of bed sediment....

Importance of Density Gradient Terms in Estuaries
In estuaries classified as well-mixed or unstratified, two-dimensional depth averaged models have often been applied with the density considered as constant. Calculations, based on measured...

Predicting Tidal Currents in San Francisco Bay Using a Spectral Model
This paper describes the formulation of a spectral (or frequency based) model which solves the linearized shallow water equations. To account for highly variable basin bathymetry, spectral...

Density Currents and Their Application in Hydraulic Engineering: Task Committee Progress Report
The Task Committee on Density Currents and Their Applications in Hydraulic Engineering operates under the Technical Committee on Hydrologic Transport and Dispersion. The Task Committee...

Slopes and Densities of Hydraulically Placed Sands

Downhole Nuclear Density Logging in Sand Tailings

Lunar Automatic Photoelectric Telescopes (LAPTs)
I propose a lunar network of modest (approximately 1 m), robust telescopes designed for and dedicated to precise, time-serial monitoring of variable sources. Unhampered by atmospheric...

An Observational Model of Far-Field Transport
Accurate numerical simulation of the transport and fate of constituents in coastal waters is made difficult by the general inability to adequately specify open-water boundary conditions...

A Survey of Selected Arctic Petroleum Drilling Locations in the Alaskan Coastal Arctic Region (abstract)
There exists in the central coastal region of arctic Alaska, a number of drill site locations which were used to explore for oil and gas in the 1960's and 1970's....
