Rehabilitation of the Historic Ocoee 1 Hydro Power Plant
The Ocoee 1 Hydro Plant is located on the Ocoee River 16 miles east of Cleveland, Tennessee. Built by the East Tennessee Power Company, it was placed in commercial operation in 1912. There...
Dillon Hydroelectric Project Performance Versus Expectations
The Dillon Hydroelectric Project was commissioned in 1987. Design and construction are briefly described; plant availability is compared with design expectations; and maintenance costs...
Decision Support for Colorado River Operations
The United States Bureau of Reclamation (Reclamation) uses a simulation model known as the 24-month Study Model for planning monthly and seasonal operations for the Colorado River Basin....
History of Lysimeter Design and Effects of Environmental Disturbances
A brief history of developments in lysimeter design is indicated. Disturbances introduced by the measurement system on the surrounding environment are discussed. The use of weighing lysimeters...
Development of Hanford Site Lysimeter Facilities
Lysimeters have been constructed at the Hanford Site near Richland, Washington to quantify mechanisms that affect migration of radioactive and hazardous waste in geologic media. The history...
Large, Monolithic, Weighing Lysimeters
Monolithic lysimeters preserve existing vegetation and soil properties that can be destroyed by excavation and filling. Site preparation for constructing large, monolithic lysimeters includes...
Lysimeter Use in Water Resources Research in China
The type, structure, development and application of lysimeter in China are reviewed in this paper. The construction and experimental observation of large non-weighing lysimeter in Ranzhuang...
Transpiration by Douglas Fir Using Lysimeters
During the spring of 1971 a 28 m Douglas fir tree was installed in a weighing lysimeter. Some details of construction are presented. The weighing mechanism consisted of eleven lengths...
Representativeness of Floating Evapotranspirometers
In the first part of the paper, the design, the working principle and the field installation of floating evapotranspirometer are described with the data logging system which delivers continuous...
Prefabricated Weighing Lysimeter for Remote Research Stations
After designing and constructing several precision scale system weighing lysimeters in Southern Europe and the Middle East, the need arose for a prefabricated 'turn-key'...
Determining Criteria for Operating Irrigation Systems
Operation variables involved in the management of given irrigation systems are the irrigation time and the inlet head, when sprinkling or drip methods are applied, or the time of cutoff...
Effect of Choptank Watershed Drainage Project on Suspended Sediment Concentration
Between 1974 and 1982, the Soil Conservation Service, U.S.D.A. conducted a sediment concentration study on the Choptank Watershed in Caroline County, Maryland to monitor the effects of...
Numerical Methods Used to Model Unsteady Canal Flow
Investigating the response characteristics of irrigation waer supply and distribution systems is essential if a good design is to be developed. Numerical simulation techniques have been...
Ground Water Modeling Using the Method of Lines (MOL)
The development of robust general purpose numerical algorithms for initial-boundary value ordinary differential equations (ODEs) which use the method of lines (MOL) makes the solution...
Enhanced Multi-Dimensional Modelling of Marshes and Wetlands
This paper summarizes the verification and application of a two-dimensional finite element model capable of simulating the complex circulation characteristics in marshes and wetlands for...
Testing a Method-of-Characteristics Model of Three-Dimensional Solute Transport in Ground Water
A new three-dimensional model of solute transport in groundwater that is based on a widely used two-dimensional method of characteristics model and is coupled to a modular finite-difference...
Predicting Incipient Fluidization of Fine Sands in Unbounded Domains
Fluidization systems in the coastal environment consist of a water pumping system and a source pipe buried in or near a tidal inlet to maintain a channel or to aid in sand bypassing. If...
Sensitivity Analysis of a Ground-Water-Flow Model
A sensitivity analysis was performed on 18 hydrological factors affecting steady-state groundwater flow in the Upper Floridan aquifer near Albany, southwestern Georgia. Computations were...
Monte Carlo Simulation of Transport from Reserve Pits
A mathematical modeling study was performed to evaluate potential health and environmental risks due to contaminant transport from exploration and production well freshwater drilling mud...
Slug Test: Double-Porosity, Linear Boundary, and Variable Storage Effects
The intention of this paper is to focus on three aspects of the slug test that are not as familiar as the main analysis techniques: the effects of double-porosity formations, the effects...
