Simulations of Multireservoir System Operation
Simulation modeling has evolved from a direct examination of operating policies into operational decision support systems, integrated multiple use expansion planning systems and special...
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...
Uplift Pressure below Gravity Dams on Rock
The magnitude of the uplift force at the base of a concrete gravity dam founded on rock is strongly dependent on the properties of the discontinuities within the rock mass. This paper...
Effect of Seepage in Cracks in Older Gravity Dams
One of the many problems encountered by dam designers is that of estimating uplift pressures in cracks within older concrete dams. As part of ongoing research, we are investigating this...
Tunnels and Vertical Shafts for Pumped-Storage
Economic considerations are of primary importance to the planning and designing of pumped-storage in an electrical generation and distribution system. This paper deals with the optimum...
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...
J. C. Boyle Hydroelectric Project Spillway Model Study
The J.C. Boyle Hydroelectric Project is an 80 MW facility near Klamath Falls, Oregon. The project consists of a concrete canal, tunnel, parallel penstocks and two Francis turbines. Upstream...
Flow Characteristics in an Irregular Spillway Model
A physical model of the spillway for a proposed water supply reservoir near Meridian, Texas, was constructed to determine the optimum spillway design which would maintain an acceptable...
Freeboard Allowances for Chute Spillways
Allowances must be made for the physical phenomena which cannot be modelled, such as wave action, air bulking, splash and spray; the simplifications of behaviour implicit in the calculations;...
Modeling a Small Side Channel Spillway-Model Testing Need Not Be Expensive or Time-Consuming
Effective hydraulic modeling can often be done without sophisticated laboratory equipment and instrumentation, yet provide adequate design information in less time and at less cost than...
Hydraulic Model Studies - Sidney A. Murray Jr., Hydroelectric Plant
The power plant is located at the Old River Control of the Lower Mississippi River (Louisiana). It consists of an intake channel about 5000 ft long, a power plant with eight bulb units...
Physical Model Study of New York State Dam
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 six channels as the water passes...
Moose River Air Chamber Design and Performance
The Moose River Hydroelectric Project is a 12.5 MW development located in upstate New York. It employs an underground air chamber to protect the unit and power tunnel from pressure surges...
Hydraulic Model Tests of Flow around Penstock Suspended inside the Tunnel for Design of a Small Hydro
The proposed hydropower project in the State of Virginia involves design and construction of a steel penstock hung from the crown of an existing outlet tunnel at this U.S. Army Corps of...
HYOPS?Maximizing the Value of Your Hydro River System
This paper presents a microcomputer based software system, HYOPS, to optimize the operations of a series of hydro plants on a river system. The model can accommodate up to 10 plants which...
Financing and Marketing Feasibility Tests for Proposed Federal Hydroelectric Power Projects
The Southwestern Power Administration (SWPA), an agency of the Department of Energy, is responsible for marketing the power and energy produced at Federal hydroelectric power projects...
Capital Cost Modelling for Micro-Hydro Appraisal
Empirical capital cost models for mini- and micro-hydro installations have not been validated with consistent site information. This paper reviews cost modelling techniques and describes...
The Use of Interior Guide Tube in Cross Flow Turbines
The Cross Flow Turbine has the distinct advantage of lower initial and operating costs over other small scale turbines, but it is believed to lack somewhat in efficiency. In this study...
Crest Gates Design for Upper Mechanicville
This paper describes the design of flap-type spillway crest gates for the Upper Mechanicville Project, located on the Hudson River near Mechanicville, New York. These gates are being provided...
Turbine Runner Procurement for the Robert Moses Niagara Power Plant Upgrade
Procurement of the new runners involved the selection of two manufacturers who have entered into a design competition in which competing models will be tested in an independent hydraulic...
