Physical Hydraulic Modeling for Construction of New York State Dam Hydroelectric Project
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 four main channels as the water...
Hydraulic Design and Development of Propeller Replacement Runner for R. H. Saunders
This paper outlines the hydraulic design for the R.H. Saunders replacement runner. The six-bladed propeller runner was numerically optimized based on 3-dimensional flow simulation. After...
Hydraulic Transients in the Operation of Small Hydro Plants
Adequate governing stability is a primary consideration for most large hydroelectric generating units. However, almost all small units installed recently in the United States are intended...
Manasan Ice Control Structure Rehabilitation & Bypass Designs
Ice control works built on the Burntwood River at Manasan Falls were damaged during the 1985 spring break-up. The ice boom had broken and the lowered pond level indicated that the rockfill...
Through-Flow Analysis for Rockfill Dam Stability Evaluations
Existing rockfill dams may have spillways that are not adequate to pass the current probable maximum flood (PMF), having been designed prior to the publication of the latest Hydrometeorological...
Frazil Ice Problems and Solutions at Hydro-Power Intakes
Active and passive frazil ice effects on hydroelectric plant intake design and operation are described and references are provided. The most frequently encountered problems and the basic...
A Case Study, Large Versus Small
This paper will review the hydraulic comparisons between the Lock and Dam No. 13 Hydropower Project, a 33-MW, low-head generating station near Fort Smith, Arkansas, and the Murray Hydroelectric...
Sidney A. Murray, Jr. Hydroelectric Power Plant Turbine Hydraulic Design and Testing
This paper describes the project design concept, highlighting the choice of turbine type and capacity. Model testing and analysis of control by downstream gate is an important feature...
Modernization of Hydroturbines?New Approach to Effectiveness, Reliability, Environment
Renovation of hydraulic turbines is one of the major lines in LMZ production and is aimed at rehabilitation of hydroturbines and increasing efficiency, rated output and energy production....

Ontario Hydro's operating philosophy is to operate all of its facilities in an optimum manner. The basic rationale for upgrading this plant is to maximize its energy potential...
Robert Moses Procurement and Model Tests ? A Contractor's Perspective
This paper discusses (1) the need to provide realistic cost/benefit evaluation criteria in turbine bid specifications and (2) the benefits of competitive model testing. Recent procurement...
Challenges in the Design and Manufacture of Small Replacement Runners
The increasing trend within the hydro industry to achieve additional capacity and/or energy through runner replacement has brought with it new challenges for the turbine manufacturer....
Dillon Hydroelectric Project Performance Versus Expectations
The Dillon Hydroelectric Project was commissioned in 1987. Design and construction are briefly described; plant availability is compared with design expectations; and maintenance costs...
Hydropower Research: The University Perspective
University hydraulic laboratories have provided applied research services for the hydropower community for many years. It is the contention of this paper that only limited technology transfer...
Waterpower 91?Laboratory Investigation of Syphon Intakes
The Federal Department of Energy, Mines and Resources (Canada) has funded four separate investigations of syphon hydro technology. These study phases, which were carried out by Acres Hydraulic...
