Center Pivots: Iron Dinosaurs of Ogallala Aquifer
In mid-1983, USDA's Soil Conservation Service (SCS) staff in Colorado began a 5-year project aimed at reducing the amount of water the state extracts from the Ogallala aquifer....
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...
Water Quality Impacts From a Flood Control Reservoir
Both qualitative and quantitative approaches were used to evaluate the impact of a flood control reservoir located on the Des Moines River in central Iowa on seven water quality parameters:...
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...
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...
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...
Bath County Pumped Storage
The Bath County Hydroelectric Pumped Storage Project provides 2,100 Mw of peak power to Virginia Electric & Power Co. and Allegheny Power Co. Called a bargain at $1.6 billion,...
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...
Microcomputers in Domestic Water System Evaluation
Water system hydraulic network analysis can be accomplished rapidly and accurately using microcomputer systems affordable by engineering firms and staffs of major water utilities. Simulations...
Computerized Information for Selecting Protected Streamflow
For developing criteria for protected flow (the flow below which water withdrawals for offstream uses are not permitted) for streams in a relatively hydrologically homogeneous region,...
Energy Dissipation in Tidal Waterways
Energy dissipation in tidal waterways is estimated analytically by a harmonic method. Calibration of harmonic parameters is done through numerical simulation. Relations between tidal energy...
Encoder for Flood and Irrigation Data Transmission
This paper covers the design and use of a new dual parameter encoder for real time telemetry in the fields of flood forecasting and irrigation. Some history and background is presented...
Evaluation of Water Distribution Network Reliability
This paper briefly describes six techniques developed for evaluating reliability of systems with complex configuration. Also, a brief comment about the computational aspects and applicability...
