Municipal Harbor Management Plans?A Solution for the 1990's
The concept and application of the Municipal Harbor Management Plan (MHMP) is one borne out of the Federal Coastal Zone Management Program. Harbor management, as a planning 'genre',...
A New Panama Canal?
Based upon the 1977 treaty between the United States and Panama and an exchange of diplomatic notes among Panama, Japan and United States, a trinational feasibility study is being conducted...
Coordinated Management of Coastal Waters in the New York-New Jersey-Connecticut Region
The U.S. Environmental Protection Agency Region II is currently funding three major water quality planning efforts for the coastal waters in the New York-New Jersey-Connecticut region....
Cross-Shore Sediment Transport Modelling and Comparison with Tests at Prototype Scale
A series of prototype scale laboratory experiments have been performed at the Large Wave Channel (GWK) in Hanover to investigate the process of sediment transport over a horizontal bed...
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...
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...
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...
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...
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...
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...
Changing Legal Issues Regarding Transfer of a Plant Up for Relicensing
Part I of the Federal Power Act ('FPA') includes a little understood, but potentially powerful mechanism for encouraging the efficient development and prudent...
Feasibility of Adding Small Hydro to Federal Hydraulic Structures in the Upper Ohio River Basin
A national hydropower program exists in which non-Federal interests may develop power at Federal hydraulic structures which have that potential. This paper discusses associated considerations...
