Nonlinear Earthquake Analysis of Concrete Gravity Dams Including Sliding
The sliding stability of a concrete gravity dam during a design earthquake must be investigated to assess the seismic safety of the dam. A new numerical procedure for solving the equations...

Application of Computer-Aided Structural Engineering
From as early as 1988, the Civil/Structural Group of Bechtel Corp.'s Houston Regional Office has viewed its automated production tools as components of a production system. Intergraph's...

Design, Construction, and Maintenance of Relief Wells
Technical Engineering and Design Guides, as adapted from the U.S. Army Corps of Engineers, No. 3 This engineering manual provides guidance and information...

Tailwater Fishery Management Using a Fish Bioenergetics Model
Water releases from TVA reservoirs exert great influence on downstream water quality. Analytical tools to quantify biological response to altered environmental conditions, such as dissolved...

Changing Dam Operating Criteria to Accommodate Aquatic Biological Diversity
The Colorado squawfish, bonytail chub, humpback chub, and razorback sucker, now threatened with extinction, were once the dominant fishes in the river. Recovering these native species...

Nakajima Subsurface Dam
A new water resource is generated by a subsurface dam. This paper presents the design, construction, and monitoring of a test subsurface dam in an alluvial valley of an island for both...

Simulating Hourly Hydropower Operations for the Assessment of Environmental and Economic Impact
Generation of peaking power at Glen Canyon Dam causes river flow and stage to fluctuate on an hourly basis. This has been shown to impact the downstream physical and biological environment....

Dam Safety Issues Related to Urban Detention Ponds
Detention ponds located within or adjacent to individual residential developments provide significant benefits by improving water quality and preventing damages from floods up to the design...

Evaluating the Steady State Stochastic Dynamic Programming Model for the High Aswan Dam
The paper describes the results of a study to critically evaluate and test the Steady State Stochastic Dynamic Programming model (SSDP). Whenever a reservoir computer model is developed,...

Locking Into Success
In 1961, at Wheeler Lock in Alabama, crews with the Tennessee Valley Authority tried to incorporate an existing lock wall into a new cofferdam. A major portion of the land wall slid about...

Roller Compacted Concrete IV
This engineering manual Roller-Compacted Concrete from the U.S. Army Corps of Engineers provides information and guidance on the use of roller-compacted...

Retaining and Flood Walls
The engineering manual Retaining and Flood Walls from the U.S. Army Corps of Engineers provides guidance for the safe design and economical...

Computer Applications in Structural Analysis and Design
The computer programs have been increasingly used in structural analysis and design to improve productivity. The computer applications in areas of automatic member and foundation design...

Estimating Sediment Relative Density Using an Impact Core Sampler and Wave Equation-based Pile Analysis
This paper presents a case history in which soil sample drive resistance was modeled with a wave equation-based pile analysis computer program to estimate in situ sediment relative densities...

Computerized Building Settlement Analyses for a Contaminated Groundwater Remediation Project
The use of spreadsheets is becoming ever more popular in the practice of civil engineering. Engineers are able to use this tool to meet deadlines which were once insurmountable. This paper...

Application of Fuzzy Logic in Civil Engineering in Japan
In various engineering fields, many applications of fuzzy logic have been attempted, some of which have been applied for practical use. In this paper, civil engineering applications of...

A GIS Foundation Example
A primary network of geodetic control monuments was developed with static GPS measurements. These monuments are tied to the existing Florida High Precision Network....

Settlement of Tanks on Clay
Steel tanks for storage of water, oil, and other liquids are capable of withstanding large, but not unlimited, settlements without damage. In most cases shallow foundations provide adequate...

Mat Foundation Design: An Historical Perspective
Nearly a half century ago, Karl Terzaghi rationalized the analysis and design of mat foundations with the conclusion that subgrade reaction was the most important variable. Soon after...

Effects of SPT Equipment and Procedures on the Design of Shallow Foundations on Sand
The effect on our computations of bearing capacity and settlement of shallow foundations suggests that as more efficient SPT hammers and procedures are used, our shallow foundation designs...
