Junction Falls Dam Rehabilitation?New Design Incorporates Vintage Concept
Junction Falls Dam was constructed in a gorge of the Kinnickinnic River in 1920 to produce hydroelectric power for the city of River Falls, Wisconsin. In 1988, the River Falls Municipal...
Uplift Reduction Using Drains
Uplift in cracks and in rock-concrete interface plays a crucial role in dam stability. Drains can be designed to intersect these cracks to reduce uplift. This paper explains how the effectiveness...
Cone Penetration Testing: Cost Effective Soil Exploration
On reviewing the 1987 Part 12 Dam Safety Inspection Reports for the Wisconsin River Power Company's Petenwell and Castle Rock Dams, the Federal Energy Regulatory Commission...
Effects of Uplift on a Gravity Arch Dam
This paper evaluates the behavior of a gravity arch dam when subjected to normal static loads and internal hydrostatic pressure (uplift). The ability to model uplift has become necessary...
Emergency Action Plans: A Need for Comprehensive Exercises
The Federal Energy Regulatory Commission's (FERC) Guidelines for Preparation of Emergency Action Plans (EAP) require that licenses conduct periodic in-depth testing, or comprehensive...
Brule Hydroelectric Project Inflow Design Flood Study
In 1987, Wisconsin Electric Power Company (WE) was directed by FERC to provide additional spillway capacity at it's 63-foot (19 m) high Brule Dam. Original spillway capacity...
Analysis and Stabilization of Ambursen Dams?Two Case Studies
Case studies are presented about the analysis and rehabilitation of two slab-and-buttress (Ambursen) dams. The paper discusses the investigation techniques used, including sampling of...
Rehabilitation of the Dams at the Crescent and Vischer Ferry Hydroelectric Projects
This paper reviews the dam rehabilitation design and construction techniques used at the New York Power Authority's Crescent and Vischer Ferry Dams. The following are the...
Outlet Works Modifications at Abiquiu Dam
For the installation of a hydroelectric project at the Corps of Engineer's Abiquiu Dam in New Mexico, outlet works modifications that would not affect the structural integrity,...
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...
Raising of King Talal Dam
The King Talal Project is located on the Zarqa River, a Jordan River tributary, in Jordan. An existing embankment dam, 100 m high, built in the mid-seventies by the Jordan Valley Authority...
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...
Rocky Mountain Project Conceptual Design of Upper Reservoir
The 9300 acre-foot upper reservoir for the Rocky Mountain Project will be formed by an 80-ft high ring dam with a crest length of 12,800 feet. Sandstone and shale of the Pottsville formation...
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,...
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...
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...
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...
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,...
Operations and Maintenance Manual for Bradley Lake Hydroelectric Project
Bradley Lake Hydroelectric Project is located on the Kenai Peninsula of Alaska. The project consists of two 63 MVA turbine-generators fed via a single 3.5-mile-long penstock. The water...
