Computerized Operation Models of Oroville Reservoir
Two monthly computer operational models, OROTHM1 and OROTHM2, were developed to provide more detailed operation and maintenance studies for the Oroville facilities. Currently another computer...

Hydrologic Dispatch Model for a Hydropower System
A hydrologic dispatch model was developed for an 11 plant, six reservoir hydroelectric system. The model incorporates load forecasting, system dispatching strategy, and database management...

Optimal Operation of the Savannah River System
This paper presents an application of a stochastic control method to the real time operation of the Savannah river system which includes three reservoirs and is expected to meet energy...

Development of Hydroelectric Scheduling Model
This paper presents the proposal preparation, pre- and post-award negotiations, and the engineering and computer software development of an hourly generation scheduling model. The Western...

Hydrologic Studies for Dinkey Creek Hydro-Electric Project
The economic analysis and final design of the 120 MW hydro-electric development on Dinkey Creek, a tributary of the North Fork of the Kings River in the Central Valley of California, requires...

Hydrologic Design Methodologies for Small-Scale Hydro at Ungauged Sites
IMP is a microcomputer package for evaluating small-scale hydroelectric power sites in British Columbia. With IMP it should be possible for an experienced hydroelectric engineer to make...

Estimating Streamflow Characteristics for Micro-hydro Sites in Northwestern Oregon
Assessing hydropower potential requires knowledge of the streamflow characteristics at prospective sites. Gaging stations are often unavailable. A method for estimating streamflow characteristics...

DURAPLOT: A Flexible Approach to Hydropower Site Optimization
The U. S. Army Corps of Engineers, North Pacific Division Office has over the past six years performed reconnaissance and feasibility level hydropower studies at a variety of sites throughout...

The Use of Time Series Analysis to Estimate Flow Duration Curves to Assess Energy Potential for Low Head Hydro Redevelopment
The proposed hydroelectric site location has a low head potential making discharge the primary energy production component. A flow duration curve (FDC) study was commenced to generate...

The Role of Headwater Benefits in Hydropower Planning
Headwater benefits are the power benefits that accure to owners of downstream hydroelectric plants as a result of the operation of headwater improvements. The retention of water in upstream...

Using Fall Streamflows as Predictors of Spring Runoff at the Dalles, Oregon
The Northwest hydropower system is characterized by a drawdown season when normally full reservoirs are drafted to meet firm obligated loads, and a refill season in which the reservoirs...

The Effect of Sedimentation on Hydro-Developments
This paper will discuss two major impacts which are the hydro construction on natural stream sedimentation and the sedimentation related problems during hydro operation. The two types...

A Case for Selecting Only Deterministic Spillway Design Floods for High Hazard Dams
The Federal Energy Regulatory Commission has under license or exemption from licensing more than 2000 hydroelectric dams. The Office of Hydropower Licensing published, in September 1986,...

Performance of Draft Tubes for Small-Hydropower Turbines
Tests of several conical and elbow-type draft tubes were conducted with varying degrees of upstream swirl. This swirl was generated by variable-geometry vanes. Draft tube efficiencies...

Small-Scale Hydro Power in Cold Climates
Small-scale hydro power is mostly developed under more pressing economical conditions than large hydro. It is therefore of great importance that the operation and maintenance costs are...

Innovative Intake Protects Both Aquatic Life and Turbine Equipment
The successful operation of small hydro projects requires an intake system with the ability to screen fish and debris from the water taken into the turbine. This separation may be required...

Appropriate Design and Construction of Conduits for Small and Mini Hydropower
The success of smaller hydro schemes often lies in identifying feasible and economic waterway systems to develop relatively high heads between low intake weir and powerstation. This paper...

Marginal Small Hydro Can be Made Viable
This paper presents the design and construction aspects of a 1,235 kW small hydro power development, comprising a new dam, gated spillway, intake canal, intake, penstock, tunnel, in-ground...

Designing a Modern Small-Scale Hydroelectric Plant
STS Consultants, Ltd. (STS) and Skidmore, Owings & Merrill (SOM) successfully teamed on four hydropower sites in Michigan during the 1980's. Three of the four sites...

Improving Design of Small Hydro Plants
One objective of this paper is to show why certain features of many small hydro plants have given poor operational performance or experienced expensive maintenance problems. A second objective...
