The Impact of Drought on Hydropower Generation-Case Study of Bureau of Reclamation Hydropower Plant
The paper explores the effects of extended drought on power generation at Shasta hydropower plant, a Bureau of Reclamation facility in Northern California. Statistical measures of water...
Evaluating the Dynamic Operating Benefits of Hydro Power Plants
In 1986, the Electric Power Research Institute asked Decision Focus to develop a new planning model to quantify the dynamic operating benefits of power technologies that offer operating...
Small and Low Head Pumped Storage Projects
With the recent completion of several very large pumped storage projects, the perception of a hydroelectric pumped storage project in some power industry circles may be that of a project...
Calculation of Three-Dimensional Turbulent Flow in Francis Turbine Runner
A numerical scheme, based on MacCormack's predictor-corrector explicit finite volume method, for solving three-dimensional weakly compressible inviscid, laminar, and turbulent...
Optimising Electric Power From a Small Scale Hydro Plant
The paper summarizes new development in electrical power generation from small scale hydro prime movers. It describes various methods of power generation such as CSCF (Constant speed constant...
Standard Safety and Control Concept for Double Regulated Small and Medium Hydro Turbines
The paper proposes a standard control concept for double regulated small and medium hydro turbines. The concept is based on minimum protection requirements for safe and reliable quick...
Operation of Hydropower Plants Considering Daily Streamflows
Operation of hydropower plants is a sequential decision process often modeled as a dynamic programming problem. Typically, such formulations consider monthly stages assuming that monthly...
Seismic Analysis of the Bonneville 1st Powerhouse
The Bonneville 1st powerhouse monoliths were constructed during the period of 1938 to 1942 and were designed against seismic loads using the old lateral coefficient method. The Corps of...
Uplift Reduction Using Drains
Uplift in cracks and in rock-concrete interface plays a crucial role in dam stability. Drains can be designed to intersect these cracks to reduce uplift. This paper explains how the effectiveness...
Penstock Rehabilitation
The deterioration of aging penstocks is a common problem at many existing hydroelectric plants. A comprehensive understanding of the physical condition and functional limitations of an...
A Rocky Mountain Project Intake/Discharge Channel Flow Simulation Study
A two-dimensional depth-integrated finite element flow model was applied to evaluate pumping and generating flow conditions at the Rocky Mountain Project powerhouse intake/discharge channel....
Evaluation of Turbine Intake Velocity Criteria
The paper addresses the effect of intake flow distribution on turbine performance at low-head projects. Field and model test data are used to raise the question of whether typical turbine...
Through-Flow Analysis for Rockfill Dam Stability Evaluations
Existing rockfill dams may have spillways that are not adequate to pass the current probable maximum flood (PMF), having been designed prior to the publication of the latest Hydrometeorological...
A Case Study, Large Versus Small
This paper will review the hydraulic comparisons between the Lock and Dam No. 13 Hydropower Project, a 33-MW, low-head generating station near Fort Smith, Arkansas, and the Murray Hydroelectric...
Performance Analysis of Multipath Acoustic Flowmeters Under Various Hydraulic Conditions
Multipath, crossed plane acoustic flowmeters are being increasingly used for hydroelectric turbine efficiency measurement both for acceptance testing and efficiency mapping of units in...
Turbines and Pump Turbines for Ultra High Heads
The paper describes the turbine development in Norway as background for high head turbine technology and shows a typical Norwegian high head Francis as an example. High head reversible...
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...
Measurement and Analysis of Hydraulic Conductivity Variability of a Heterogeneous Aquifer
The spatial variability of hydraulic conductivity of a shallow alluvial aquifer was investigated using borehole flowmeter measurements. The study was conducted at the site of a large-scale...
An Energy Approach to the Analysis of Partially-Saturated Flow
When fluid passes into or out of an aquifer, work is done at the boundaries which is partly used to change the internal energy of the system and partly to overcome resistance to flow....
