Seismic Probabilistic Risk Assessment for Critical Facilities
Probabilistic Risk Assessment (PRA) for seismic events is currently being performed for nuclear power plants. The background on seismic PRA is presented along with a basic description...
Electric Utility Noise Emissions
Environmental regulations require that impact statements for new electric utility and industrial power plants include an evaluation of noise emissions. Variations in equipment sound power...
Environmental Noise Control for Industrial Facilities
The authors present a brief discussion of the criteria used to evaluate environmental noise control problems. Then, they discuss environmental noise control in the power, petroleum, gas...
Design and Operating Rules for Reservoir Storage to Offset Future Consumptive Use
The Washington Metropolitan Area (WMA) relies largely on the Potomac River for water supply. After many years of study, a coordinated regional operating plan was adopted by the water supply...
Software Authoring for the Rest of Us
Extensive use of high resolution graphics, form-oriented full screen data entry, and contextual help messages have proven to be an effective means of structuring the dialogue between the...
HEC5 Hydropower Simulation Enhancements
Acres version of HEC5 possesses enhancements in the logic governing conventional hydropower, pumped-storage, and system power simulation. This paper demonstrates the conventional hydropower...
Computerized Operation of California State Water Project
Hydraulic and electrical schedules for the California State Water Project are determined and dispatched from the Project Operation Control Center (POCC) in Sacramento. The dispatched schedules...
Optimization in Water Resources Planning
Recently developed optimization software represents significant first steps toward the application of the digital computer as a design and planning tool. This software has recently been...
Environmental Auditing?TVA's Experience
TVA has conducted 70 audits of various TVA operations including construction projects and power plants since 1981. In general, TVA's experience with environmental audits has...
Geothermal Salt Recovery From Evaporating Ponds
The water from geothermal reservoir 'Los Azufres' in Michoacan, Mexico, is characterized by its high content of chloride, silica, borum and arsenic. Due to the...
Estimating Transmission Losses
Infiltration or transmission losses in ephemeral stream channels are an important part of the water balance in arid and semiarid regions. The governing equations for movement of flood...
Effect of Wetted Perimeter on Infiltration in Furrows
Five empirical infiltration equations were evaluated using data from blocked infiltrometer tests with wetted perimeter values ranging from 28 to 49 cm. The results indicate that the Kostiakov...
Development and Management of the Northern Colorado Water Conservancy District
This paper discusses and explains the Northern Colorado Water Conservancy District. The purposes, accomplishments, operation and management, and financing of the District are mentioned....
Incorporating Crop Water Use in Drainage Design in Arid Areas
A method of drainage design for use in arid areas was developed by combining procedures proposed by D. B. McWhorter along with plant uptake functions developed by D. W. Grimes and D. W....
Appropriated Water Rights in Utah
The appropriated water rights system used in Utah is discussed. The historical background for establishing this allocation process is reviewed. The process of changing the location and...
Channels and Groundwater: The Hydraulic Connection
Hydraulic connection between surface and groundwater implies that surface water can seep into the ground (transmission losses from open channels, for example) and eventually become or...
Modeling the Fate and Transport of Biocides in Estuarine Power Plant Cooling Water Discharges
This paper presents a framework with examples for understanding the fate and transport of cooling system discharges into estuaries through the use of modeling. The modeling of biofouling...
Coastal and Ocean Resources for Energy Development
There has been a growing interest in renewable alternative sources of energy. An increasing effort is being directed towards the problem of extracting energy from the world's...
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...
