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...

Engineering Risk Assessment for Hydro Facilities
Faced with escalating property insurance premiums, the Alaska Energy Authority decided to evaluate what losses may realistically be expected due to catastrophic events at their hydroelectric...

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...

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...

Dam Safety Rehabilitation of the T.V.A. Nickajack Hydroelectric Project
Safety of its dams has always been of great concern to the Tennessee Valley Authority (TVA). The agency has throughout its history enforced conservative designs, good construction practices,...

Junction Falls Dam Rehabilitation?New Design Incorporates Vintage Concept
Junction Falls Dam was constructed in a gorge of the Kinnickinnic River in 1920 to produce hydroelectric power for the city of River Falls, Wisconsin. In 1988, the River Falls Municipal...

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...

The Replacement of Penstocks at TVA Ocoee II Power Plant
The Tennessee Valley Authority (TVA) replaced the steel penstocks at its Ocoee II power plant near Ocoee, Tennessee. A total replacement was necessary because of severe corrosion on the...

Rehabilitation of the Dams at the Crescent and Vischer Ferry Hydroelectric Projects
This paper reviews the dam rehabilitation design and construction techniques used at the New York Power Authority's Crescent and Vischer Ferry Dams. The following are the...
