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...
Structural Safety Studies
Structural engineers are most concerned with the safety aspect of structures. The primary objective of structural engineers is to produce structures which are satisfactory in meeting certain...
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....
Texas Hiplex Experimental Design
Research into rainfall enhancement in Texas expanded rapidly during the 1970's with the Texas HIPLEX program. More recently, the states of Texas and Oklahoma and the United...
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...
Oil Spill Risk Assessment for Marine Vessels
An oil spill risk assessment study should show the estimated relationship between the magnitude of an adverse environmental impact and the probability of equaling or exceeding that impact....
Prior Planning for Post-Hurricane Reconstruction
Planning for hurricane emergencies has focused upon the period immediately before and after the storm's arrival, emphasizing evacuation and disaster relief. Mitigation of...
Managing the Dunes and Wetlands of Norfolk, Va.
The Code of the City of Norfolk was amended in 1982 to establish a procedure for permitting and preservation of the city's saltmarshes and sand dunes. A Wetlands Board was...
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...
Geological Processes and Conservation Management Strategies for Barrier Islands of the Virginia Coast Reserve
A barrier island is a sandy deposit that is located immediately offshore and parallels a mainland coast. It is the principal environment of six interactive environments that make up the...
A Tidal Gauge System in New York Harbor
For over a year, a Real Time Wind and Water Level Telemetry System (RTWLTS or Tidal Gauge System) in New York Harbor has been generating real time data 24 hours per day on actual harbor...
Beach Erosion Mechanics
Beach erosion along the coasts affects economic, political and conservation conditions. This paper defines the mechanics of the Coriolis Effect, caused by earth spin, along with storm...
The Statistics of Storm-Induced Sediment Resuspension
The passage of a storm increases the wind stress applied to the sea surface. This surface stress is partially dissipated as it is transmitted through the water column. Some fraction of...
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...
