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...
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...
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...
Complete Recyling in the Organics Chemicals Industry
Regulations for both direct and indirect discharges have become so stringent in order to protect the environment that wastewater treatment and effluent levels in the organics chemicals...
Case Studies of POTW Air Toxic Emission Tests and a Proposed Emission Control Strategy
Air toxic emissions and associated human health risk at wastewater treatment plants can be reduced with a phased implementation strategy. An evaluation of major conventional secondary...
Using Multiple Water Quality Models for Determining Variable Emission Levels for Wasteload Allocation
We present a methodology for determining the least-cost wasteload allocations from multiple point sources discharging into a single water body. The system of point sources is modeled as...
Performance Analysis of Remedial Alternatives
This paper demonstrates how remedial action alternatives for a Superfund site can be evaluated using a health-risk basis. The case history for this demonstration is a Feasibility Study...
An Analysis of Modeling Techniques in Pollution Management of Natural Water Systems
This paper will focus on various models to demonstrate the difficulties with modeling techniques. The difficulty with developing a valid model for a system is explored through the study...
Trihalomethane Control: A Case Study
Controlling trihalomethanes (THMs) has been an important part of many utilities' water treatment programs since THMs were first regulated in 1979. The increased disinfection...
A Case Study in Sludge Handling
When the Wyoming Valley Sanitary Authority (WVSA) converted its operation to a secondary treatment plant in 1988, something important was missing. That something was a method to handle...
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...
Hydroproject Risk Analysis
Traditionally, feasibility studies performed for potential hydropower sites have included either no uncertainty or at best an ad hoc value associated with estimated benefits. However,...
Renovation and Uprating of Seven Hydropower Plants in Java
The Indonesian Power Authority is planning to renovate and uprate seven hydropower stations in Java to expand plant life expectancy, ensure operating safety and reliability, and increase...
Fish Entrainment and Mortality at the French Landing Hydroelectric Powerhouse
This case study explains the fish mortality study performed and results obtained at an existing hydroelectric powerhouse in Michigan. Undertaken in 1989 and 1990, this study provides data...
