Discharge Zone Classification System for Southern Puget Sound
This paper identifies marine areas where new or expanded discharges are unacceptable based on existing knowledge; e. g. , water quality standards are currently not met, and impairment...
Priorities for Federal Marine Pollution Research
To provide guidance for the national marine pollution research and monitoring program, a workshop was held recently to identify and assign priorities to the marine pollution issues facing...
Anadromous Fish Impacts at Proposed Hydroelectric Plants
This paper describes a series of field techniques successfully used by the authors to determine a minimum flow downstream of hydroelectric plants. The minimum flow of water required for...
Zooplankton Entrainment Evaluation in a Power Plant Station
The impact study on the Setubal thermal plant included an evaluation of the plant's effects on zooplankton in the outlet area. After entrainment in the cooling system there...
Beneficial Use of Municipal Sewage in the Ocean
When sewage sludges and effluents are introduced in a properly controlled manner, they can be of benefit to large areas of the ocean. For example, benthic biomass and growth rates of commercially-valuable...
Monitoring Environmental Impacts from Waste Disposal in the Deep Ocean
Deep ocean sites are presently being considered for the permanent disposal of wastes. Their environmental acceptability can only be assessed by an efficient and effective monitoring plan....
Transition in the Nuclear Industry
Significant changes have occurred within the utility industry within the past 10 years. Projected growth in electric power demand has not materialized. Nuclear power plants, with long...
Waste Cleanup: Lessons Learned
Since hazardous waste mitigation is a new science, engineers need to pass on their experiences. The U. S. Army Waterways Experiment Station, seeking to expand the hazardous waste knowledge...
Helms Pumped Storage Project
The powerhouse at California's Helms Pumped Storage Project is 1,200 ft below the surface of the Sierra Nevada mountains. Linking existing reservoirs, the project provides...
Project Mixes Oil and Water
The Prudhoe Bay Seawater Treatment Plant was nominated for an OCEA award, for its potential to coax from Alaska's north slope 1 billion barrels of oil which otherwise would...
Hydropower Surveys with Microcomputers
A microcomputer program, HYFEAS, has been written in BASIC for use in pre-feasibility assessments of a given site. HYFEAS uses a flow duration curve, headwater and tailwater curves, information...
Reliability Analysis of Water System Capacity
The paper presents, by means of an application, a few promising analytical methods for estimating bulk water system capacity reliability. In particular, this paper examines the applicability...
Browns Ferry Nuclear Plant: Twenty Years Experience with Changing Thermal Criteria
This paper and its companion papers focus on one aspect of the environmental impact of Browns Ferry - the discharge of heated water. The paper provides a description of the site and the...
Browns Ferry Nuclear Plant Thermal Compliance Monitoring Network: Utilization of Data
An automated water temperature monitoring network was designed to measure ambient and downstream heated river temperatures at Browns Ferry Nuclear Plant (BFN) in Wheeler Reservoir. The...
Applications of a Diffuser Performance Model at Browns Ferry Nuclear Plant
An unsteady flow model and a diffuser performance formulation were combined to more accurately determine plant-induced temperature effects. This model has been applied to several aspects...
Field Evaluation of a Diffuser-Induced Mixing Model
Early physical model studies of the diffusers at Browns Ferry Nuclear Plant qualitatively document the mixing characteristics of the thermal effluent. Based on these studies, the dilution...
Simulation of Far-Field Thermal Effects from Browns Ferry Nuclear Plant
A computer model was used to evaluate the far-field effects of revised thermal discharge limitations at the Tennessee Valley Authority's Browns Ferry Nuclear Plant (BFN)....
Integrated Hydrothermodynamic Study of Browns Ferry Nuclear Plant
The results of hydrothermodynamic analyses and computer models discussed in previous papers are combined to present an integrated study supporting a request for alternative thermal limits...
Physical and Chemical Behavior of Chrysotile Asbestos Particles in Natural Waters
The paper reports on research to develop a better understanding of the chemical behavior and the influence of surface chemistry on the physical behavior of chrysotile asbestos and other...
Computer Simulation of Coagulation
Coagulation, the process of collision and coalescence of particles, modifies the size distribution of the suspended mass, continuously creating larger particles which may settle out of...
