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...
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...
Water Plan Deals Carson City a Good Hand?Carson City Revisited
The success of Carson City's new wastewater treatment plant is no surprise. It results from the City's Comprehensive Water Plan (CWP) for ultimate wastewater...
UV Disinfection of Wastewater: A Pilot-Scale Study of Performance
A pilot-scale study of UV disinfection under field conditions was conducted. Inactivation and photoreactivation was well correlated with UV dose. Standards of 100 coliform/100 mL were...
Evaluation of the City of Venice Urban Reuse Program
The City of Venice is located on the Gulf of Mexico in west central Florida. With a mild sub-tropical climate and coastal location, the small community is a prime target for rapid development....
EPA Guidelines for Water Reuse
The U.S. Environmental Protection Agency and the U.S. Agency for International Development are cosponsoring preparation of water reuse guidelines. The guidelines are being developed to...
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...
Chemical Composition, Physical Properties and Off-Site Migration of Municipal Landfill Gas
A sampling program of headspace gas from four monitoring wells and of off-site migration at three property line sites was conducted as part of a remedial design of a municipal landfill....
An Evaluation of Area Source Dispersion Algorithms
The correct simulation of air pollutant dispersion from area sources of pollutants has presented some unique challenges to dispersion modelers. This study employs geometric tests and sensitivity...
Inside the Manhole: New Design on a Leaky Link
Wastewater collection systems represent a major investment for every community, not only in capital dollars, but also in the well-being of community members. Though sanitary sewer manholes...
Navy Targets Effective Infiltration/Inflow Elimination
The Naval Facilities Engineering Command (NAVFAC), Chesapeake Division, retained the services of RJN Environmental Associates, Inc. to perform a Sanitary Sewer Evaluation Survey (SSES)....
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...
Environmentally Sustainable Development: A Concept in Action
Environmentally sustainable development denotes a balanced approach with appropriate consideration for environmental protection. The successes achieved in the development of five diverse...
Propositions for Packed Bed Adsorption Reactor Design
This paper states ten propositions which describe the behavior of 'wave fronts', i.e., adsorbate concentration versus distance profiles at given elapsed times,...
Toxicity Bioassay Using Nitrifying Bacteria
Monitoring water quality by the use of toxicity bioassay was studied with respect to the interrelationship between nitrifying activities, ammonium and inorganic compounds. Differential...
