Characteristics of Flow Pressure Pulsation and Similitude Law of Model
As described in this paper, the characteristics of flow pressure pulsation and similitude law of model are derived from experiments on some prototype dam and serial scales models....
Effects of Spillway Operation on Cavitation Damage to Hugh Keenleyside Dam Spillway
The Hugh Keenleyside Dam (also known as Arrow Dam) is located on the Columbia River, at the outlet of Lower Arrow Lake, 53 km north of the Canada - U.S.A. border. The project has been...
Chute Design Using Concrete Building Blocks
Chutes constructed using concrete building blocks for erosion control on ephemeral streams have performed successfully. The chutes consist of a layer of blocks placed on a geotextile over...
CCM Overtopping Protection on Three Parkway Dams
Cellular concrete mat (CCM) overtopping protection systems have been designed for and will be installed on three small embankment dams along the Blue Ridge Parkway. Based on recent field...
Overtopping Protection for Embankment Dams
Modifications that allow safe overtopping during large flood events can be made to existing embankment dams. These modifications are on the leading edge of technology and require special...
Utilization of Stormwater Runoff to Recharge Underlying Aquifer
The expanding economy in Oman has led to rapid development in the Capital area. Water is critical to sustaining this rapid growth, and new sources of water are being sought to meet the...
Spillway Gates for the El Naranjero Dam in Spain
In June 1986 Zwag Zschokke Wartmann Ltd received the order from Hidroelectrica Espanola S.A. in Madrid, Spain for the design and model testing of 5 radial gates on the 'El...
Diversion Closure Gate Schemes Used on B.C. Hydro Dams
Over the last 25 years B.C. Hydro has designed, built and has operated a number of large dams and continues to do so. This paper describes the design, erection and operating experiences...
Field Installation of Strain Gaged Geotextiles
High-strength polyester geotextiles were used in two major Corps of Engineers projects: Wilmington Harbor, Del. and New Bedford, Mass. To verify design assumptions and as part of monitoring...
Thermomechanical Damage Due to Hydration in Large Concrete Dams
This paper presents the bases of a thermomechanical model able to describe the main evolution of concrete properties with aging. The model is based on the 'maturity'...
Leveling the Playing Field
As professional sports grow, so does the market for elaborate multi-use sports arenas. The new Target Center in Minneapolis features a unique movable floor, 68 luxury suites and a state-of-the-art...
Anchoring a Dam
To comply with Federal Energy Regulatory Commission requirements with regard to stability under a postulated Probable Maximum Flood, an extensive foundation investigation and stability...
Development of Hydraulic Structures
The Bureau of Reclamation was established in 1902. Since that time, Reclamation has constructed more than 220 dams. Each dam, depending on its function, has two or more principal hydraulic...
Geosynthetic Shields For Dams
A series of large dams in Europe, waterproofed by geosynthetics, may become U.S. prototypes. In Europe, the faces of more than 30 large dams now contain geotextiles and geomembranes. In...
An Optimal Design of Steel Pipe Pile Foundation
This paper presents an optimal design method for the steel pipe pile foundation of bridge pier using a nonlinear programming. It is firstly assumed that an imaginary wall model behaves...
BABE: An Expert System for Structural Design of Bridge Abutments and Piers
A knowledge-based expert system named 'BABE' (Bridge and Building Evaluation) has been developed for the purpose of helping the user in planning, analysis and...
Current Research and Future Developments
A review of current research projects at the National Science Foundation on bridge engineering are reviewed and discussed with respect to immediate and future impacts. A look into the...
Effects of Vertical Motion on the Inelastic Behavior of Highway Bridges
The response of typical highway bridges to the vertical component of earthquake ground motion has a significant effect on their elastic behavior. When vertical motions are considered along...
System Identification of Earth Dams Using Seismic Records
A technique to identify the elasto-plastic dynamic properties of earth dams and, therefore to asses the capabilities and limitation of their models, is developed. The technique is based...
Characteristics of a Structure-Foundation System
The dynamic characteristics of the structure-foundation system of a 1/4 -scale nuclear power plant containment model is studied using seismic records. The model structure is treated as...
