Characteristics of the Flood Release-Induced Vibrations with Qianshui Thin-Arch Dam
In this article the prototype observations and design analyses are described regarding the flood release-induced vibrations of the Qianshui thin-arch dam and its foundation; and their...

Hermite-Galerkin Model for Dam-Break Floods
A model based on the finite element method using cubic Hermite basis functions and Galerkin weighting was formulated to solve the partial differential equations that govern unsteady one-dimensional...

Hydraulic Modeling of Boating Hazards and Sedimentation?Union Avenue Dam, Denver Colorado
Hydraulic jump type energy dissipators are a hazard to recreational boaters. Many white water boaters have been trapped in 'reverse roller' hydraulic jumps. Numerous...

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...

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'...

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...

American Experiments with Laminated and Multiple-Membered Arches
This chapter explores the history of laminated and multiple-membered arches in America....

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...

Beautiful Bridges and Highways in the West
This paper recounts 75 years of progress in the design of aesthetic bridges and highways in the west. Not a new idea, there are numerous existing examples showing that the goal of good...

Two-Level Optimization of Nonlinear Structures
This paper presents several optimization design problems and their applications to both cable structures and geometrically nonlinear braced-rib arches. The sum of squares of residuals...

Looking at the Past
The story of bridge building is related through a look at the bridges of the past, from earliest bridges of record to the latest cable-stayed successes. Progress in bridge development...

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...
