Articifical Nourishment at Varadero Beach, Cuba
Following severe storm damage at Varadero Beach during the winter of 1986-87, beach nourishment was carried out at Punta Blanca (17,000 m³), Hotel...

Littoral Environmental Considerations of a Barrier Island in Beach Fill Design: Key Biscayne, Florida
An analysis and understanding of morphodynamic and littoral processes along a coastal shoreline is important in design of a beach fill project. Morphodynamic analysis should include a...

Performance of a Beach Nourishment Project Based on Detailed Multi-Year Monitoring: Redington Beach, FL
A recent monitoring project of a beach nourishment project includes closely spaced profiles and sediment analysis which provides data on nourishment performance which can be used in management...

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...

The Use of Aragonite as an Alternate Source of Beach Fill in Southeast Florida
The first full-scale use in the United States of imported aragonite sand for beach restoration was initiated at Fisher Island, Florida, in December, 1990. The project involved placement...

Dredging & Nourishment Bulk Determination by Sediment Budget
'Ria' is the Spanish name for a sea flooded valley, whatever its origin and evolution. This paper discusses a project involving the regeneration and protection...

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...

Performance Analysis of Multipath Acoustic Flowmeters Under Various Hydraulic Conditions
Multipath, crossed plane acoustic flowmeters are being increasingly used for hydroelectric turbine efficiency measurement both for acceptance testing and efficiency mapping of units in...

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...

Rheological Properties of Simulated Debris Flows in the Laboratory Environment
Steady debris flows with or without a snout are simulated in a 'conveyor-belt' flume using dry glass spheres of a uniform size, 5 or 14 mm in diameter, and their...

A Hybrid Model for Sediment Concentration Profiles
The paper discusses the deficiency in the existing theories on suspended concentration profiles which is due to the variations of theories for modeling the velocity profiles. As can be...

Comparison of Correction Factor for Dispersion Coefficient Based on Entropy and Logarithmic Velocity Profiles
Recently, new velocity distribution equations have been developed by Chiu (1987, 1989) through the use of maximum entropy principle. A comparison will be made of the correction factor...

Compact Pump Sump Design
This paper details the design criteria chosen to construct a pump sump within several on-site constrictions. The physical size restrictions of the site necessitated the construction of...

Hydraulic Analysis for the Shot Tower Subway Station Beneath the Jones Falls
The objective of the hydraulic analysis is the formulation of a strategy to safely accommodate the construction of the Shot Tower Metro Station beneath the existing Jones Falls. The hydraulic...

Effect of Barrier Beach Breaching on Harbor Dynamics and Storm Surges
This paper presents a summary of the flood insurance study, commissioned by the Federal Emergency Management Agency, to determine the 100-year flood elevation for Chatham, a seacoast town...

Shell Island Restoration
Shell Island is a barrier island along the Louisiana coast that protects back bays and marsh land south of New Orleans. In 1979, the island was breached by a hurricane, exposing the back...

Beach Evolution in Sulphur Island
Seasonal variation of shore area of Sulphur Island is studied by analyzing aerial photographs of the island taken seasonally for the past two years. Analysis reveals that shore area in...

Effects of Tide on Variation of Beach Profile
Effects of tide on variation of beach profile are examined experimentally. It is clarified that tidal effect appears differently when it acts on beach of different profiles. Namely, in...

Momentum and Kinetic Energy Coefficient Research?Ramp Flumes
In October 1984. Reclamation Hydraulic Branch staff members investigated the operation of the A-Canal ramp at Klamath Falls, Oregon. The ramp flume was completed in 1983 as a water measurement...

Patterns of Erosion Along the Atlantic Coast
Shoreline erosion data are needed in the implementation of recent legislation that authorizes the National Flood Insurance Program (NFIP) to provide advance insurance payments for the...
