The Wisconsin River System Operations Model: WIRSOM
The passage of the Electric Consumers Protection Act of 1986 requires the Federal Energy Regulatory Commission to give equal consideration to non-power as well as power values in hydroelectric...

A Flow Forecasting System for Hydro Power
The flow forecasting system comprises a network of meteorological stations, a weather forecasting model, and a watershed hydrologic model, implemented in a microcomputer. The meteorological...

Pressure-Time Flow Measurements Under Adverse Conditions
Theoretical analyses suggest that the pressure-time method is capable of accurately determining flow rate in the short, varying cross section, 'semi-scroll' penstocks...

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...

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....

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...

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...

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...

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...

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...

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...

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...

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...

Colorado River Probable Maximum Floods
Upper limit design rainstorms (ULDRS) were developed for three locations in the Colorado River drainage above Hoover Dam. For each location, the rainfall magnitudes, spatial and temporal...

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...

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...
