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...

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,...

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...

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...

Characteristics of Colloids in Landfill Leachate
Leachate was collected from a municipal landfill which has been closed for about 15 years. The sample was collected (under a N₂ atmosphere) only...

High Level Radioactive Waste Management 1991
The proceedings of the second annual international conference on High Level Radioactive Waste Management, held on April 28 - May 3, 1991, Las Vegas, Nevada, provides information on the...

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...

Consideration of Sedimentation on Hydropower Projects
Experience gained by analysis of a number of hydropower projects throughout the world leads to the conclusion that it is necessary to consider sediment related aspects in the design and...

Estimation of Loading via Fingered Flow
Results of experimental investigations of fingered preferential flow are combined into a concise, conservative engineering methodology for predicting pollutant transport through fingered...

Impact of Grid Orientation on Groundwater Contaminant Transport Modeling Using the U.S.G.S. MOC Model
The U.S.G.S. method of characteristics (MOC) model was enhanced to include the input of measured contaminant concentrations, the calculation of computed and measured contaminant plume...

Pitfalls Associated with the Assumption of a Constant Partition Coefficient in Modeling Sorbing Solute Transport Through the Subsurface
This paper presents several case studies where the estimation of the adsorption coefficient, K_d, by means of the K_oc-f_oc...

Modeling of Reactive Chemical Transport of Leachates from a Utility Fly-Ash Disposal Site
Fly ash from fossil-fuel power plants is commonly slurried and pumped to disposal sites. The utility industry is interested in finding out whether any hazardous constituents might leach...

2-D Groundwater Transport of Reactive Solutes with Competitive Adsorption
This paper presents a 2-D model, with applications, for the groundwater transport with competitive adsorption of a metal, a ligand and a complex. The model, called METLI, computes advection-dominated...

Monte Carlo Simulation of Transport from Reserve Pits
A mathematical modeling study was performed to evaluate potential health and environmental risks due to contaminant transport from exploration and production well freshwater drilling mud...

Simulation of Leachate Discharge from a Small Island into a Tidal Bay
A small island in a tidal bay was considered as a potential site for depositing large volumes of excavation material from a transportation project. The island is located in the inner part...
