Rehabilitation and Replacement of Slab and Buttress Dams at the Wissota Hydroelectric Project
The Wissota Hydroelectric Project is a 70 year old slab and buttress dam which required rehabilitation due to deteriorating concrete. Due to restrictions imposed by the FERC and Owner,...

Rocky Mountain Project Seepage Cutoff in Solutioned Limestone
The right abutment of the main closure dam for the Rocky Mountain Project required extensive treatment of deeply weathered shale and solutioned limestone to assure control of seepage and...

Potholes East Canal Headworks Project
The construction of 6.5 MW Potholes East Canal Headworks in Washington required near vertical excavation of about 100 ft (30 m) through the existing earthfill dam founded on columnar basalt....

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...

Rocky Mountain Project Power Tunnel Filling Test
The Rocky Mountain Project, a pumped storage development located in NW Georgia, is owned jointly by Oglethorpe Power Corporation and Georgia Power Company. Initial construction included...

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....

Sungai Piah Hydroelectric Project (Malaysia)
The Sungai Piah Hydroelectric Project is located in the State of Perak in Peninsular Malaysia. It is a run-of-river project on steep mountain streams in dense tropical jungle. Nine intakes,...

Rocky Mountain Project?Probable Maximum Floods
Probable maximum floods (PMF's) were estimated for use in designing spillways for the lower reservoir main dam and two auxiliary pool dams at the Rocky Mountain pumped-storage...

Validation Studies on Indexed Sequential Modeling for the Colorado River Basin
A method called indexed sequential modeling (ISM) has been developed by the Western Area Power Administration to estimate reliable levels of project dependable power capacity (PDC) and...

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...

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...

Implications of the 1987-1990 Droughts for Hydropower Generation at Reclamation Powerplants
Droughts in the western United States beginning in 1987 have caused water supply shortages and required rationing of water in some areas. The reductions in water supply have also impacted...

Assessment of Changes at Glen Canyon Dam
This paper describes the complexity associated with the assessment of financial impacts of proposed and actual short-term restrictions at Glen Canyon Dam. The reasons for these restrictions...

An Artificial Intelligence Approach to Multiple Reservoir Operation
The modeling of complex river basins using symbolic computer languages, object-oriented programming and knowledge-based reasoning facilitates, the application of optimization techniques...

Evaluating Hydro Project Benefits with the POWRSYM Production Cost Model
The contribution that a hydro peaking project or pumped-storage project makes to reducing system operating costs can be determined only by modeling the project's operation...

Consideration of Sedimentation on Hydropower Projects
Experience gained by analysis of a number of hydropower projects throughout the world leads to the conclusion that it is necessary to consider sediment related aspects in the design and...

Columbia River System Operation Review
For many years hydroelectric power has been a surplus commodity in the Pacific Northwest. However, this picture has been changing rapidly in recent years. Increasing pressures for use...

An Improved Incremental Economic Dispatch Method for Hydroelectric Generators with Nonconvex Energy Production Cost Curves
The Bureau of Reclamation (Reclamation) has undertaken a program to improve water resource management at its hydroelectric powerplants. One feature of the resource optimization program...

Development of the Collett Reservoir Addition to the Muck Valley Hydroelectric Project
The existing 26 MW Muck Valley Hydroelectric Project is located on the Pit River, 90 miles east of Redding in Northastern California. The Project was licensed by the Federal Energy Regulatory...
