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...

The Importance of Large Landsat Data Sets for Isolating Sediment Resuspension Processes
An optical density analysis of Landsat film transparencies would show spatial variations of suspended sediment concentrations. The residual optical density profile inversely shows above...

Protecting the Reservation Environment Under the Coastal Zone Management Act
Current federal law and practice does not provide direction for the development of Indian tribal coastal zone management programs. The relationship between state, federal and tribal governments...

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....

Forecasting Currents in Coastal Waters
A service for current and temperature forecasts has been developed for the coastal waters along the west coast casts has led to several improvements. Future modeling efforts are expected...

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...

Sea Level Changes: A Corps of Engineers Perspective
The purpose of this discussion paper is to review current Corps of Engineers policy in relation to a possible significant increase in general sea level. A significant relative sea level...

Armor Protection for Rubble Mound Breakwaters
A brief summary of past practices in breakwater armor system design is presented. The limitations of current design procedures for rubble mound breakwaters are discussed and improved methods...

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....

Satellites Monitor Eutrophication of Estuaries
In a study on eutrophication of estuaries, NOAA/AVHRR satellite data have been analyzed for the Changjiang River plume and the adjacent coastal areas. The different regimes identified...

Measurements of Near-Survface Current in Inlets and Bays with Synthetic Aperture Radar
Synthetic Aperture Radar, SAR, provides images of land and ocean surfaces irrespective of solar illumination, and practically under all weather conditions. Developed originally for land...

Coastal Zone '87
Coastal Zone '87 is the fifth in a series of multidisciplinary meetings on comprehensive coastal and ocean management. The papers included in this publication review technical...

The Evolution of a Factory Insulated Piping System
This paper reviews the developments over the past fifteen years in a factory insulated high density polyethylene piping system that has become a standard for sewage and water piping systems...

Sediment Penetration in Lakes as a Result of Dredged Material Disposal and River Sediment Loads
Pollutant transport within the coastal boundary layer is highly sensitive to the vertical current structure and to the magnitude of the vertical current, especially during upwelling and...
