Wave-Induced Scour Prediction at Vertical Walls
Scour at the foot of a vertical wall is examined for the special case of normally-incident, nonbreaking irregular waves that are perfectly reflected by the wall. The bottom is initially...
Artificial Headland and Submerged Groyne for a Beach Improvement Project
The design approach that was used to determine the length and elevation of a submerged groyne as well as a system for providing adjustment to the elevation of the submerged groyne is presented....
An Artificial Perched-Gravel Beach as a Shore Protection Structure
Gravel beaches provide the backshore of coastal environments with a protective buffer from wave erosion. A case study is presented of the conceptual design and utility of an artificial...
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'....
Monitoring of a Nearshore Disposal Mound at Silver Strand State Park
The migration of an underwater disposal berm constructed in December 1988 approximately six miles south of the entrance to San Diego Bay is investigated. The berm was composed of medium...
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...
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...
Complex Principal Component Analysis of Wave-Like Sand Motions
Complex Principal Component Analysis is applied to bathymetric data from the SUPERDUCK experiment at Duck, NC. This approach is shown to describe more of the variation with fewer functions...
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...
Topographic Responses to the Construction of Large Port Structures on Oarai Coast
Large offshore breakwater and groins have been constructed at Oarai Port, Japan. As a result, the coast experienced significant topographic changes. In this paper, the responses of the...
Transport of Volatile Organic Compounds (VOCs) Through a Clay Liner
A series of tests have been performed using laboratory-scale flexible wall permeameters. A synthetic organic leachate mixture of methylene chloride, toluene, and trichloroethylene (TCE)...
PITTLEACH: A Numerical Model of Landfill Stabilization
This paper addresses the theoretical development, use and application of PITTLEACH, a computer program conceived to simulate the processes of landfill stabilization. Since the physical,...
Implementation of Vertical Landfill Expansion
Montgomery County, Maryland, proposed to implement a vertical expansion or 'piggyback' design for the County's municipal solid waste landfill. The...
An Integrated Study of Air Toxics Emissions from an MSW Landfill
An integrated approach was used for a study of air toxics emissions at a municipal solid waste (MSW) landfill (LF) consisting of field sampling, emission estimation, atmospheric dispersion...
Land Disposal Restrictions and Mixed Waste Management
The Land Disposal Restrictions, imposed by Congress in 1984 and implemented by the Environmental Protection Agency, impose constraints on the management of mixed waste. Except in very...
Combined Nitrogen and Phosphorus Removal in a Cyclic Activated Sludge System Without Anoxic Mixing Sequences
A simplified methodology for combined phosphorus and nitrogen removal through reactor configuration, cyclic sequencing and the control of aeration intensity in variable volume activated...
Remedial Planning for the Former EXPO 86 Site
This paper describes the site characterization and remedial action planning effort that is being undertaken at the former EXPO 86 site in downtown Vancouver, B.C. The 200 acre site on...
Adsorption of Lindane onto Whole Soil and Soil Organic Fractions
The work presented here investigated interactions of the subject pesticide with whole soil and select soil organic fractions and evaluated the commonly applied assumptions that adsorption...
