Unique Design Used for Collapsible Gate
The collapsible gate on the Wausau Dam is unique; there is only one known that is similar in design. The collapsible gate, which looks like an inverted V, was designed by Mead and Hunt...
Double Radial Gates for the Brunau Ice-Retention Weir in Switzerland
During the springtime thaw, the River Sihl, which flows from the south into the city of Zurich, Switzerland, carries large quantities of ice flow. In 1968, to protect the footings of a...
Three Dimensional Modeling of Concrete Dams with Cracks Using Boundary Element Methods
Determining uplift pressure distributions in cracks in a concrete dam requires coupling between crack hydraulics and the stresses and displacements occurring in the rock and the concrete...
Avoiding Vibration in Penstocks
One objective of this paper is to indicate the potential sources of pressure pulsations within a hydraulic conduit system and the range of forcing frequencies associated with these sources....
Prefabricated Power Plants, Experience and Prospects
This paper presents the prefabrication concept applied to the Greenup (Greenup Locks and Dam, Ohio River, 72 MW, 1982) and the Sydney A. Murray, Jr. (Old River Control Structures, Vidalia,...
Hydraulic Model Studies?Pak Mun Hydroelectric Project (Thailand)
The paper presents briefly the hydraulic problems related to the project which were successfully solved by the 1 to 100 scale hydraulic model study carried out at the Asian Institute of...
Hydraulic Aspects of West Delaware Tunnel Hydroelectric Development
Construction of a 7,500 kilowatt hydroelectric plant at the end of a 70 kilometer long water supply tunnel posed unusual hydraulic conditions that needed special consideration. Cooperation...
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...
Modernization of the Schoolfield Dam Hydroelectric Powerhouse
This case study describes the retrofitting of a turn-of-the-century powerhouse with modern turbine/generator equipment. The structure consists of numerous turbine bays separated by massive...
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...
Rehabilitation of Dams, Spillways, and Hydroplants
Many older dams are in need of rehabilitation as a result of aging, deterioration, and more stringent safety standards. Concerns include deterioration of original construction materials,...
Dewatering Using a Floating Bulkhead Proves Flexible, Reusable and Cost Effective
Going beyond a traditional bulkhead dropped in place with a barge crane or crane hoist, a steel floating bulkhead was conceived to dewater powerplant intakes, gated spillway bays or outlet...
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....
R. H. Saunders GS?Propeller Turbine Runner Replacement Project Outline and Model Development
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...
