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

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...

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...

Examples of Risk Assessment in Dam Safety Decision Making
Three examples of risk-based dam safety evaluations performed for dam users or operators are summarized. These studies were conducted by major U.S. engineering firms and involved experienced...

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...

Stability Analysis of Gravity Dam Foundations with Horizontal Seams
Determination of the overall factor of safety against sliding is an important aspect in concrete dam design. Limit equilibrium methods have serious limitations. A method for determining...

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...
