Decision Support for Short Term Export Sales From a Hydroelectric System
A stochastic dynamic programming (SDP) model was recently developed and implemented at British Columbia Hydro and Power Authority (B.C. Hydro) to provide decision support for short term...
Hydropower Stochastic Forecasting and Optimization
A microcomputer package was implemented to support real-time decisions for weekly and month-end water management at an industrial complex in the mountains of British Columbia. The rolling...
Application of Principal-Component Analysis to Long-Term Reservoir Management
Determining the optimal long-term operating policy of a multireservoir power system requires solution of a stochastic nonlinear programming problem. The paper presents a very efficient...
Computerized Decision-Guidance System for Management of the Trent River Multireservoir System
A computer simulation model has been implemented for a complex multireservoir system, composed of 44 reservoirs and 52 channels. The model is designed in modular form to forecast inflows,...
Brief Description of Castor Software for Management of Reservoir Systems
The CASTOR group, started in 1984 at Ecole Polytechnique de Montreal (Canada), is a major software development project for an integrated CAD system related to hydro projects. Based on...
Heuristics and Network Flow Algorithms for Multireservoir System Regulation
A generalized model employing a network flow algorithm and a heuristic database is being tested on the Qu'Appelle River basin in Canada. The heuristic database consisting...
Ports '89

Design, Construction and Testing of Repairs to the Low Level Outlets at Terzaghi Dam
Operation of the low level outlets (LLOs) at Terzaghi Dam in southwestern British Columbia resulted in severe cavitation at operating heads significantly lower than design. Modifications...
Design and Operation of Guard Gates
Guard gates for hydroelectric intakes and low-level outlets are normally intended for operation only under balanced heads. In the case of failure of regulating gates, the guard gate may...
Borden Field Data and Multivariate Geostatistics
A large-scale field experiment on natural gradient transport of solutes in groundwater was conducted in an unconfined sand aquifer in Borden, Ontario by extensive monitoring after the...
The Hydro Business: 1990 and Beyond
During the last ten years, hydroelectric generation received more and more attention as a source of reliable and economical electricity. Since the first WATERPOWER conference, the industry...
IJC Challenges in an Era of Uncertainty
Since its creation pursuant to the 1909 Boundary Waters Treaty between the United States and Canada, the International Joint Commission (IJC) has evolved into an effective mechanism for...
Economic Trade-Off between Hydropower and Other Competing Water Uses: A Case of Coteau Creek Station
Using the Coteau Creek hydropower generating station in Saskatchewan as a case study, economic trade-offs between water used for hydropower generation, and irrigation and recreational...
First 10 Years of Operation of
The first turbine of the La Grande hydroelectric Complex (Quebec, Canada) was commissioned in october 1979. Since then, five reservoirs, two rivers diversions, three power stations with...
Hydrometric Networks Serving Hydropower Needs
The Water Resources Branch is the national agency that collects, interprets and disseminates standardized surface water quantity and sediment data and information in Canada. The Branch...
Tunneling through an Existing Concrete Masonry Dam
The Gregory B. Jarvis Hydroelectric Project is located in Upper New York State on the West Canada Creek. Existing facilities include a non-overflow concrete gravity dam, 65 feet long and...
A Comparative Hydraulic Model Study of an Orifice Spillway
The results of a hydraulic model study to investigate the feasibility of using an orifice spillway at a generating station in northern Manitoba, Canada are presented. It has been suggested...
Ghost Dam Safety Evaluation
Ghost Development, owned and operated by TransAlta Utilities, is near the eastern margin of the Rocky Mountain Foothills, approximately 33 km northwest of Calgary, Alberta. The development...
Mitigation of Ice Effects at Hydroelectric Intake Structures
The design and operation of hydroelectric facilities throughout the northeast United States and Canada must contend with winter conditions for a large part of their yearly operation. During...
Effects of the Environmental Approval Process on Project Scheduling and Economics
