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...

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...

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...

Bishop Intake #2 Spillway Modifications: A Case History
This paper covers the history of the events leading to the modification of Southern California Edison's (SCE) Bishop Intake 2 to pass a site specific design flood. From the...

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...

Unique Design Used for Collapsible Gate
The collapsible gate on the Wausau Dam is unique; there is only one known that is similar in design. The collapsible gate, which looks like an inverted V, was designed by Mead and Hunt...

Double Radial Gates for the Brunau Ice-Retention Weir in Switzerland
During the springtime thaw, the River Sihl, which flows from the south into the city of Zurich, Switzerland, carries large quantities of ice flow. In 1968, to protect the footings of a...

Raising of King Talal Dam
The King Talal Project is located on the Zarqa River, a Jordan River tributary, in Jordan. An existing embankment dam, 100 m high, built in the mid-seventies by the Jordan Valley Authority...

Avoiding Vibration in Penstocks
One objective of this paper is to indicate the potential sources of pressure pulsations within a hydraulic conduit system and the range of forcing frequencies associated with these sources....

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...

Rocky Mountain Project?Overview
The Rocky Mountain Project, in Northwest Georgia, will be a three unit hydroelectric pumped-storage project with 850,000 kW installed in an above ground powerhouse. The gross water volumes...

Hydraulic Model Studies?Pak Mun Hydroelectric Project (Thailand)
The paper presents briefly the hydraulic problems related to the project which were successfully solved by the 1 to 100 scale hydraulic model study carried out at the Asian Institute of...

Hydraulic Aspects of West Delaware Tunnel Hydroelectric Development
Construction of a 7,500 kilowatt hydroelectric plant at the end of a 70 kilometer long water supply tunnel posed unusual hydraulic conditions that needed special consideration. Cooperation...

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....

Physical Hydraulic Modeling for Construction of New York State Dam Hydroelectric Project
The New York State Dam is located on the Mohawk River near its confluence with the Hudson River. Downstream from the dam, the river flow is divided into four main channels as the water...

Field Tests of a Lewiston Pump-Generating Unit
An extensive field test program was undertaken on a Lewiston Pump-Generating Plant (LPGP) unit at the Niagara Power Project, owned and operated by the New York Power Authority. The objective...

Hydraulic Design and Development of Propeller Replacement Runner for R. H. Saunders
This paper outlines the hydraulic design for the R.H. Saunders replacement runner. The six-bladed propeller runner was numerically optimized based on 3-dimensional flow simulation. After...
