Lake Siskiyou Power Project
The Lake Siskiyou Power Project was constructed at the foot of the existing Box Canyon Dam on the Sacramento River in Northern California. Major project features included the construction...
Net and Hydroacoustic Monitoring of Fish Passage
In 1986 EPRI published a review of available fish protection technologies for use at hydroelectric facilities. One major conclusion of that study was that fish protection systems were...
Screening Data with an Expert System (PDAS)
The performance of a three-mile long penstock, constructed in an active landslide area in northern California, is monitored using 138 vibrating wire-strain gauges. Readings are taken daily,...
Design of Powerhouse Spiral Case Considering Three-Dimensional Action
A commonly used approach of designing semi-spiral cases for Kaplan turbine installation using two-dimensional frames becomes unsuitable for large diameter turbines and/or high heads. The...
Optimal Real-Time Control of Hydroelectric Power Plant Using Dynamic Programming
In this paper, an approach of optimal real-time control of hydroelectric power plant operations is presented. The methodology is based on a dynamic programming technique where the original...
Measurements of Time Lag in Concrete Gravity Dam Foundations
Uplift measurements from eight large concrete gravity dams show that the time lag between an increase in headwater level and a corresponding increase in uplift pressure is insignificant....
Geotechnical Aspects of the Underground Excavations at the Kemano Completion Project
The Kemano Completion Project is the addition of four generators of 540 MW installed capacity to an existing eight-unit underground hydroelectric generating station owned and operated...
Soil Nails as Temporary Powerhouse Support
Newcastle Powerhouse was constructed as an underground structure with its top deck at the finished ground surface. The powerhouse is three-quarter circular and one-quarter square in plan....
An Alternative Approach to the Maximum Flood Concept
This paper outlines an alternative to the current approach for determining the maximum flood of river basins. The condition of the maximum flood is derived from the convolution integral...
Streamflow Gaging in a Remote Area Using Cellular Telephone Telemetry
A case study will be presented describing the utilization of cellular phone technology in a remote sensing situation. Because expected annual energy estimates are vital in planning small...
Case Study: Steele Creek Dam Safety Analysis, Bristol, Tennessee
Steele Creek Dam creates a small recreational park lake before discharging into Beaver Creek a few hundred yards below the dam. Existing homes and trailers downstream from this junction...
Risk Analysis Applications for Dam Safety
Dam safety modifications are intended either to reduce the likelihood of the adverse consequences of dam failure or the magnitude of adverse consequences. For instance, widening a spillway...
The Stabilization of Minidoka Powerplant and Dam
The rehabilitation of structures can pose numerous challenges to the engineer. The structure historical preservation, the benefit cost ratio of the rehabilitation, and the stability of...
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...
Estimating Uplift in Cracks in Concrete Dams
Results are presented of a three year research program on the modeling of uplift pressures in cracks in concrete gravity dams, and the effectiveness of drains in reducing those pressures....
Dam Stabilization/Modification at Lighthouse Hill and Schuylerville Hydropower Developments
Remedial measures including posttensioning of concrete structures, earth dike armoring, tainter gate modification and replacement of deteriorated concrete to meet federal and state hydraulic...
Cone Penetration Testing: Cost Effective Soil Exploration
On reviewing the 1987 Part 12 Dam Safety Inspection Reports for the Wisconsin River Power Company's Petenwell and Castle Rock Dams, the Federal Energy Regulatory Commission...
Effects of Uplift on a Gravity Arch Dam
This paper evaluates the behavior of a gravity arch dam when subjected to normal static loads and internal hydrostatic pressure (uplift). The ability to model uplift has become necessary...
Brule Hydroelectric Project Inflow Design Flood Study
In 1987, Wisconsin Electric Power Company (WE) was directed by FERC to provide additional spillway capacity at it's 63-foot (19 m) high Brule Dam. Original spillway capacity...
Analysis and Stabilization of Ambursen Dams?Two Case Studies
Case studies are presented about the analysis and rehabilitation of two slab-and-buttress (Ambursen) dams. The paper discusses the investigation techniques used, including sampling of...
