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...

Coastal Process Study on Beacon Shoreline
A sediment budget was developed for the Santa Barbara and Ventura County shoreline in Southern California as part of an overall coastal planning effort. The budget was analyzed primarily...

The Santa Cruz Littoral Cell: Difficulties in Quantifying a Coastal Sediment Budget
Beach compartments or littoral cells form the framework for our understanding of the sources, transport, sinks, and storage of sand in the nearshore zone. In general, along the California...

Waenhuiskrans: Sediment Budget and Reactivation of a Sediment Pathway
Erosion of beaches due to historical dune stabilisation work carried out at Waenhuiskrans, a holiday village on the south-east coast of South Africa, prompted the need for the reactivation...

The Ebro Delta Project: A First Sediment Budget
In this paper, a sedimentary budget for the Ebro delta coast in the Western Mediterranean is presented. Calculations have been performed after one year of field campaign. The main result...

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 --...

North Fork Feather River Erosion Control Program
PG&E, an investor owned gas and electric utility serving northern and central California, has been engaged since 1984 in the development and implementation of a regional erosion...

Cavitation Noise Investigation of a Pump-Turbine
The results from cavitation noise detection measurements on a 35 MW pump-turbine are presented. Detailed information about the cavitation noise is determined including three-dimensional...

Erosion Potential of Pacific Basin Precipitation
Average annual erosivity (EI) values were developed using 20 years of hourly precipitation data from weather stations located on each of 10 Pacific Basin islands. Average annual erosivity...

Irrigation Management to Control Sediment Pollution
Unchecked serious irrigation erosion occurs on 20% or 10+ million irrigated acres in the U.S. It may cause water use impairment from sediment pollution. Serious erosion in many areas can...

Hydraulic Aspects of Grade Control Structures
This paper describes the function of grade control structures. The primary purpose of a grade control structure is to maintain or establish a desired bed elevation in a channel. Basically...

Relationship Between Scour Depth and Bend Radius of Curvature on the Red River
Studies of bank and bend processes were undertaken on the Red River between Index, Arkansas and Shreveport, Louisiana in connection with the navigation project on the river downstream...

Riprap Design Criteria for the ARS Low Drop Structure
The ARS low drop grade control structure has proven to be an effective means to stabilize incised channels in Mississippi. However, field inspections and laboratory testing have indicated...

Operational Procedures for Estimating Bottom Exchange Rates
After briefly reviewing the terminology of the various bottom and water column exchange fluxes, the body of this paper summarizes five possible procedures for establishing operational...

Evaluation of Embankment Erosion at TVA's Chickamauga Project
Studies were made to evaluate the extent of erosion to be expected under probable maximum flood (PMF) conditions. The erosion studies were made using the EMBANK computer program. The results...

Rio Moquino Stream Stability and Erosion Protection, Jackpile Uranium Mine
The uniqueness of the Jackpile Reclamation Project and the changes in reclamation technology over the past few years have prompted a reexamination of some of the design criteria specified...

Temperature Rise, Bank Erosion, and Jet Velocity Effects of Submerged Multiport Diffusers in an Estuary
Temperature distributions, potential bank erosion, and jet velocity and trajectory of submerged multiport diffusers were predicted as part of the permitting process for an fossil fuel...

Loose Riprap Grade Control Structure Design
The Soil Conservation Service has been using loose riprap grade control structures based on the equal energy concept for several years with mixed success. Previous model studies resulted...

Pavement Materials for ASTOVL Aircraft Application
Jet blast impingement on concrete is a problem today and will worsen when the new vectored-thrust aircraft become operational. Ground erosion has already been observed under the auxiliary...

Working Breakwaters
Along the Virginia portion of the Chesapeake Bay, shoreline erosion has erased about 40,000 acres of land since 1850. Now a series of headland breakwater systems stems erosion up and down...
