An Evaluation of the Applicability and Cost of Polyester Resin and Cementitious Grouts for the Installation of Rock Anchors at Hydro Projects
The success of two proposed hydropower projects in the States of Virginia, and West Virginia depended on the ability of a rock anchor system to support the penstocks at the crown of the...

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...

Considerations to Be Taken in the Design of Speed Increasers for Hydroturbine Service
The paper discusses the incorporation of a speed increaser specification that is primarily functional yet one that will address the cost, reliability, efficiency, and life requirements...

Hydro Turbine Submergence
The elevation of a hydro-electric turbine above or below tailwater is based on hydraulic model studies to determine the critical sigma, defined as the ratio of barometric pressure plus...

Pit Turbines, an Economical Solution for Low Heads
The paper describes the experience with pit turbine design and construction at the 8 MW St. Cloud facility located on the Mississippi River in Minnesota. Major topics in the paper include...

Design and Efficiency Testing of a Cross-Flow Turbine
An inexpensive American-made cross-flow turbine was designed, manufactured, and installed at a remote run-of-river site in Northern California. The 400 kW unit includes an innovative automatic...

Harnessing the Allegheny: Four Low-Head Projects
The navigable portion of the river, extending northeast of Pittsburgh approximately sixty miles, contains eight lock and dam systems under the jurisdiction of the U.S. Army Corps of Engineers...

Turbine Conceptions for Low Heads and Their Application in US Hydro Power Stations
To improve the feasibility of small power plants standardized units were developed. The bulb turbine technology as well as the pit-type conception improve the feasibility of larger plants....

Visual Scheduling
This paper presents a look at new innovative way to provide project schedule. The primary target is in visual scheduling presentation techniques. The systems presented include a system...

Movable Dam?Gate Selection Procedure
Very few new dams are now being considered, particularly for waterpower and even more specifically for low head waterpower in the lower reaches of major rivers. The City of Harrisburg,...

Fish Mortality at a New Low-Head Hydroelectric Plant
A study was developed for the Morrow Plant to investigate the potential for turbine related mortality of entrained fish. Morrow Lake supports a small sport fishery, mainly for smallmouth...

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...

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...

Status and Prospectives of Small Hydro Power Development in Egypt
The paper describes the current status of hydropower development in Egypt and its future prospects. Emphasis is made on reviewing the potentialities for small, mini and micro-hydropower...

Large Capacity Rock Anchors Stabilize Bagnell Dam
Evaluations of spillway discharge capacity and stability of structures for the Osage Hydroelectric Project indicated that the Project was unsafe during the occurrence of the Probable Maximum...

The Rehabilitation of Lake Harriet Dam
In 1984, the decision was made to rehabilitate the Lake Harriet Dam. The existing arch dam structure was encased with a rockfill buttress. The downstream buttress, which also acts as a...

Design of Siphon Penstocks for Low Head Hydros
Siphon penstocks have been designed and constructed at Jim Falls and Winter, Wisconsin at existing dams. Both hydropower projects are located on the Chippewa River. The design of these...

Civil Design of Underground Hydro Power Projects
Various reasons exist for the development of underground schemes. Limited space at dam sites in deep and narrow river valleys makes it favourable to separate the power house from the dam...

Rock Engineering at Cat Arm Hydroelectric Development
Cat Arm Hydroelectric Development in Newfoundland, Canada, develops 129 MW from 384 m of head. The project was constructed between 1981 and 1984 and comprises 5 large dams, 5 small dams,...

The Effect of Geology on the Dinkey Creek Project
The proposed Dinkey Creek Project is located about 40 miles northeast of Fresno, California. The project consists of a 360-foot high rockfill dam, two powerhouses, 41,600 feet of power...
