Making Amends with Nature
The U.S. salmon population has been decimated in the last half-century, principally because of hydropower. In the nation's focus on alternate and clean energy sources, fish...
An Evaluation of Pile Design in Fraser River Delta Using In-Situ Tests
Modern methods of pile design often take advantage of in-situ test data. Thirteen axial pile capacity design methods have been evaluated using the results from eight full-scale pile load...
Analysis of Pile Load Tests at Lock and Dam 26
This is a summary of the results collected during the extensive load test program performed by the U.S. Army Engineer District, St. Louis, during the construction of the new Lock and Dam...
Performance of a Large Ribbed Mat on Cohesive Soil
The performance of a 678-ft by 304-ft (207-m by 93-m) ribbed concrete mat was studied to provide improved soil input parameters for design. The mat was constructed on a low plasticity...
Interpretation of Instrumented Driven Steel Pipe Piles
This paper presents the results of a series of studies on the behavior of driven close-ended steel pipe piles. Extensive field explorations and geotechnical analyses have been carried...
Cost Effective Pile Foundation Supports Fast Track Paper Mill
This paper decribes the generalized subsurface conditions, pile evaluation and load test program, pile and piling contractor selection, production pile installation, and quality assurance...
Innovative Foundation Designs for Permafrost Conditions in the Arctic
This paper describes the engineering solution to restore the structural properties of permafrost at a site location in the Western Operating Area of the Prudhoe Bay Field. Steel pile supports...
Steel Structures
The seventy-eight papers included in this volume cover the fifteen sessions generally associated with steel structures presented at the Seventh Annual Structures Congress held on May 1-5,...
Pressure Relief Design Around Pumping Plants
Hydraulic transient protection for an irrigation pipeline pump station can include optimized operating procedures, or design of surge relief equipment such as surge relief valves, and...
Locating and Sizing Air Release Valves on Irrigation Systems
This writing is directed to persons involved in irrigation systems and describes the usage of air release and vacuum valves. Principles described are applicable to many other piping systems,...
TVA: A Half-Century of Sedimentation Experience
The Tennessee Valley Authority (TVA) is a regional resource development agency, created by the United States Congress in 1933 and charged with bringing to the Tennessee River watershed...
Hydraulic Mechanisms of Riverbank Erosion
Recent efforts are described to develop an improved understanding of bank failure due to piping in noncohesive layers in riverbanks. The efforts included field surveys and laboratory tests....
Analysis of Pumping Station and Force Main Networks
A computer program to simulate the performance of wastewater pumping station and force main networks is discussed. Results are presented which compare system performance for steady and...
Closed Conduit Vapor Lock
Closed conduit vapor lock can occur when a cross country liquid pipeline is displaced with a gas and the gas is allowed to get ahead of the liquid/gas interface. A simple hydraulic model...
Water Distribution System Design Considering Component Failure During Static Conditions
A continuous hydraulic availability relationship is presented which more realistically models minimum pressure requirements for water distribution systems. This relationship is used in...
Challenging Site Conditions Lead to Unusual and Innovative Powerhouse Design Features
Pacific Gas & Electric Company's recently completed Newcastle Powerhouse is located on the shore of Folsom Lake near Auburn, California. The $26 million facility uses...
Design of Steel Tunnel Liners
The paper presents a detailed development of the fundamental equations for internal pressure design, considering an elastic interaction between the steel liner and the surrounding rock...
Managing the Columbia River to Meet Anadromous Fish Requirements
According to northwest fishery agencies and Indian tribes the protection for juvenile salmon and steelhead is not adequate. The Northwest Power Planning Council, formed as the result of...
The Construction of the Sidney A. Murray, Jr. Hydroelectric Power Plant
The project, consisting of eight 8.2m bulb turbines rated at 192MW, is located in the State of Louisiana and will use a portion of the water diverted from the Mississippi River to the...
Vibration Problems of Penstock Piping for a Vertical Tubular Hydraulic Turbine
