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...

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...

Controls on Sand Resources: Cape Canaveral Area, Florida
Analysis of Holocene stratigraphy and sediments of the continental shelf off Cape Canaveral Florida shows that three basic factors control the quality of sand resources. Antecedent topography...

Cross-Shore Sediment Transport Determined by EOF Method
Laboratory and field data of beach profile changes are used to study the cross-shore transport rate. The Empirical Orthogonal Eigenfunction analysis is applied to separate the temporal...

Higher Frequency Acoustic Measurements of Coarse Bedload Transport
Although sensors have been developed which provide high temporal resolution for the measurement of wave profiles, flow fields and suspended sediment concentrations within the coastal system,...

Standing Wave Measurements of Bedload Thickness: Feasibility in an Air System with Model Sediment
A novel technique would yield information about bedload thickness from measurements of a standing wave pattern produced by a sound source insonifying the bottom at normal incidence. The...

Integrated Photogrammetric and Geophysical Monitoring of Shoreline Instability in Littoral Cells in the Pacific Northwest, USA
Several factors have recently focused on the attention of government agencies, academic researchers, and the general public on coastal erosion and beach resource management in the Pacific...

Coastal Sediment Budget Analysis Techniques
Sediment budget analysis techniques developed by the U.S. Army Corps of Engineers Wilmington District are described. The basic procedure combines information on shoreline and tidal inlet...

Sediment Budget at Oceanside, California, Calculated Using a Calibrated Shoreline Change Model
A quantitative sediment budget analysis was made for the shoreline segment extending from 4 miles north to 4 miles south of Oceanside Harbor using a calibrated shoreline change model....

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...

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...

Modifications for Extending the Treatment Capacity
An approach for minimizing influences of increasing raw wastewater flow rates is proposed, based on modifying existing primary sedimentation units, by transforming them to flocculation...

Pilot-scale Trickling Filter Nitrification at the Longmont WWTP
Nitrification rates in trickling filters can be affected by influent organic matter, filter length, and hydraulic loading rate. The effects of these parameters on nitrification rate were...

Inventory of Constructed Wetlands for Municipal Wastewater Treatment in the U.S.
The U.S. EPA's Risk Reduction Engineering Laboratory is conducting an inventory of constructed wetlands (CW) for municipal wastewater treatment in the U.S. The inventory is...

Vacuum Anaerobic Treatment: A New Approach
Anaerobic processes have an organic loading limit that when exceeded leads to process failure. The research summarized in this paper demonstrates that both organic removal rate enhancement...

LRFD: Still Waiting
Introduced in 1986, load and resistance factor design (LRFD), has a way to go before it becomes standard practice for steel design. LRFD-based design typically results in savings on gravity...

Probing the Golden Gate
The Golden Gate Bridge has just come through the most detailed analysis ever attempted in its 53-year-old history. This analysis was squeezed into a desktop computer that calculates twice...
