Processes of Sediment Transport and Ebb Tidal Delta Development at a Jettied Inlet
This paper deals with the development of the ebb tidal delta following the extension of jetties at a tidal river entrance. The growth rate and morphological change are discussed using...

Residual Currents—The Variability of an Inlet Sediment Trapping Mechanism

Infragravity Wave Motion in a Tidal Inlet
Infragravity waves (20

Sorting Characteristics of Tidal Inlets
An hypothesis is presented as follows: Littoral processes at a tidal inlet remove a disproportionately higher quantity of fine grain sediment than coarse grain sediment from the littoral...

New Dredging Technology for Inlets and Beaches: Move Sand to the Pump
Conventional dredging for channel maintenance and 'mining' of offshore sand for beach restoration and renourishment 'moves the pump to the sand'....

Beach Nourishment Episodes at the Sandy Hook Unit, Gateway National Recreation Area, New Jersey, USA: A Preliminary Comparison
A chronic erosion problem at Sandy Hook resulted in two major beach nourishment operations during the 1980's, employing material dredged from nearby navigation channels. Grain...

Recent Evolution and Potential Causal Mechanisms of Cedar Island, Virginia, 1852-1986
Shoreline mapping was used to reconstruct the historical shoreline evolution of Cedar Island, Virginia in an effort to clarify the debate on barrier island response to sea level rise --...

Hydraulic Model Studies for Non-Federal Projects at Federal Dams—A Case Study
This paper will discuss the hydraulic model studies for hydropower projects developed by Arkansas Electric Cooperative Corporation (a non-federal entity) at existing Corps of Engineers...

Prefabricated Power Plants, Experience and Prospects
This paper presents the prefabrication concept applied to the Greenup (Greenup Locks and Dam, Ohio River, 72 MW, 1982) and the Sydney A. Murray, Jr. (Old River Control Structures, Vidalia,...

A Case Study, Large Versus Small
This paper will review the hydraulic comparisons between the Lock and Dam No. 13 Hydropower Project, a 33-MW, low-head generating station near Fort Smith, Arkansas, and the Murray Hydroelectric...

Determining Criteria for Operating Irrigation Systems
Operation variables involved in the management of given irrigation systems are the irrigation time and the inlet head, when sprinkling or drip methods are applied, or the time of cutoff...

Predicting Incipient Fluidization of Fine Sands in Unbounded Domains
Fluidization systems in the coastal environment consist of a water pumping system and a source pipe buried in or near a tidal inlet to maintain a channel or to aid in sand bypassing. If...

New Lessons About the Hydraulic Performance of Highway Storm Sewer Inlets
Laboratory experiments were performed with highway storm water curb inlets to 1) reduce the oblique standing wave that extends into the highway from the downstream side of the inlet and...

Issues and Challenges Facing the Effective Delivery of Scientific Visualization
The availability of economical hardware and software products for scientific visualization has stimulated implementation of scientific visualization within high performance computing environments....

Data Acquisition Systems for IBM Compatible System
Portable data acquisition systems composed of IBM compatible PC/XT/AT computers and analog to digital conversion cards can be configured with relative ease. These systems have the flexibility...

Ambient Suspended Sediment Concentration and Turbidity Levels
The temporal variation of suspended sediment concentration and turbidity is an important component of the riverine environment. The maximum rate of discrete volumetric sample collection...

Return Velocities Induced by Shallow-Draft Navigation
Return velocities are caused by the displacement effects of vessels as they travel in navigation channels. Numerous return velocity equations have been developed for relatively small channels...

A Knowledge-Based System for the Environmental Design of Waterways (ENDOW)
Knowledge-based software systems accept problem descriptions from users and apply logic in order to generate a solution or solution set. These systems function over very narrow problem...

An Engineering Analysis of Sedimentation in Tidal Inlets
The engineering comparative analysis of deposition and scour of noncohesive sediments in the neighborhood of bridges over tidal inlets is a unique problem which does not lend itself conveniently...

Partnering on the Bonneville Navigation Lock
The Portland District of the Corps of Engineers has found partnering to be a valuable technique for contract and project management. This paper presents details of the execution of the...
