Expanding Groundwater Production in Southern California
The incentive to achieve greater conjunctive use in Southern California has been provided by the Metropolitan Water District of Southern California through a special pricing mechanism...
A Reservoir Yield Evaluation in an Arid Climate
Yield calculations rarely can be more accurate than roughly plus or minus twenty percent. The same uncertainty is dramatically greater in arid climates where the average annual runoff...
Conservativeness in Hydraulic Engineering Studies
Hydraulic engineers routinely make a variety of assumptions during the course of a study. Assumptions, once made, usually become incorporated into the fabric of the study and are seldom...
Variational Method in Fluvial Hydraulics?A Review
The theoretical base of the principle of minimum energy dissipation rate and other related stationarity hypotheses have been reviewed. Recent applications of the theory to the calculation...
Mt. Elbert Pumped Storage Trashrack Failure
The failure of three trashrack sections for unit 2 at the suction-draft tube intake occured after one year in service. However, the trashracks for unit 1 had five years of service with...
On the Problem of Sediment Deposition in Large Reservoirs
Sediment deposition and its accumulation in a large reservoir depends on the inflow and reservoir storage content, respectively. This fact is used to model the cumulative deposition of...
Experimental Study on the Hydraulic Characteristic and Trapping Efficiency of a Vortex Tube Sediment Trap
In this paper, an expression of water extractor ratio of a vortex tube has been obtained according to the principle of energy conservation and transformation; based on the feature of sediment...
A Study on Estimation of Aquifer Parameters in Unsteady Seepage Flow
A method which automatically identifies aquifer parameters is proposed in this paper. The aim of this investigations is to estimate transmissivities and storage coefficients of unsteady...
Overview of International Ocean Energy Activities
An overview is presented of international research and development activities in four energy conversion areas: ocean thermal energy conversion (OTEC); wave energy conversion; tidal energy...
An Update on the U.S. DOE Ocean Energy Program
This paper summarizes recent research accomplishments of the program and provides a synopsis of planned activities leading to a Net Power-Producing Experiment (NPPE), to be conducted at...
Ocean Energy Activities in China
The ocean energy will perform an important action to compensate for energy consumption. In China tidal energy was utilized early, building tidal power plants began from the nineteen fifties....
Ocean Energy Activities in Europe
This paper reviews European research and development in wave energy, ocean thermal energy conversion (OTEC), and ocean tidal power. For each technology, a country-by-country summary (in...
Theoretical Study on Capture Chamber with Lateral Entrance
A capture chamber with lateral entrance can be used in a pneumatic wave energy conversion system. In this paper, the output power coefficients of the capture chamber have been calculated...
Research and Development of Wave Pump
A new device, 'Wave Pump' is introduced here. The authors present the mechanism of the system, the analytical method for discharge rate, the hydraulic model test...
Wave Power Development in Taiwan
The feasibility study of wave power development in Taiwan was performed in two phases. The first phase included the calculation and assessment of the available wave energy along the coasts...
Planning a Full Scale Wave Power Conversion Test 1988-1989
The paper describes the design of the wave power converter and the principal of working. The results from a tank test on a scale model are presented with the main emphasis on design loads...
Use of Scrap Tires to Harness Wave Energy
A 2.5 meter diameter wave powered pump, fabricated from scrap tires was tested from May 24, 1988 to October 1988 in the Atlantic Ocean at the North Carolina Army Corp of Engineers Waterways...
Some Novel Concepts in Approach to Harnessing Tidal Power
The worldwide tidal energy potential remains undeveloped because of its low power density and high cost of constructing conventional hydroturbine power plants. The objective of this paper...
Review of Garolim Tidal Power Project
The feasibility study of Garolim tidal power project made in 1981 was reviewed in 1986 and updated in 1988. The review study generally confirmed the result of the 1981 study. The generator...
