An Alternative to the Peripheral Canal
The present mode of water transfer through the Sacramento—San Joaquin Delta is not adequate to meet both future export requirements and maintain desired water quality. A 42-mile long Peripheral...

Hydraulic Regime and Activated Sludge Performance
The standard bio-kinetic theory used to describe the activated sludge process predicts that the soluble organic matter (SOM) concentration in the effluent of plug flow aeration tanks will...

New Structural Systems for Zero-Maintenance Pavements
Unique and infrequently used concepts and systems suitable for zero-maintenance pavements are identified. For this study, a zero-maintenance pavement is defined as one that will provide...

One Uses His Umbrella When It Rains
The engineering profession unity movement is reviewed, with a brief explanation of the reasons for forming the American Association of Engineering Societies. A brief historical background...

Water Law Primer
An overview of legal principles controlling water resources use and development is provided. The body of legal principles is a combination of federal and state law, with federal law generally...

Selection of Pavement Joint Sealant Material
A review of literature shows joint sealant selection should be based on the design, construction and environmental variables. Satisfactory performance for one set of conditions does not...

Exact Involute Bodies of Revolution
Involute construction is an approach used in contemporary rocket nozzle technology for the fabrication of exit cones and other bodies of revolution and consists of laminating identical...

Piping Potential of Weak Zones Under Concrete Dams
A method is presented for evaluating the piping potential of shear zones crossing the foundation of a concrete dam from upstream to downstream. The steps described for this method involves...

Finite Beams on Elastic Foundation with Restraints
A solution is presented of the differential equation of finite beams with elastic restraints, resting on a Winkler foundation in terms of the initial conditions at one end of the beam....

Postbuckling of Rings under Two Uniform Loads
The interaction effect of the normal and centrally directed pressures on the initial postbuckling behavior of a thin elastic circular ring buckling freely in its own plane is investigated...

Symmetrical FFT for Migrating Waves
A Fast Fourier Transform (FFT) technique is developed to analyze migrating waves for phase relationships as well as spectra. The problem of phase leakage, which arises through the use...

Supervisory Problems in International Construction
The success of supervisors on construction projects is, to a large extent dependent upon their ability to develop effective interpersonal relationships with their subordinates. The task...

The Resident Engineer: Intermediary Between Owner and Contractor
The resident engineer must possess significant talents other than the necessary technical abilities that qualify him for his position. The tactful and diplomatic handling of project interrelationships...

Sampling with Decomposed Variance
In many problems of statistical sampling in civil engineering a prior distribution reflecting some global population is available and a small sample of observations is made on a particular...

Quality Control During Construction of Power Plants
The need for quality control during the construction of power plants has always been recognized as beneficial. Federal law requires a comprehensive program be provided to control and assure...

Approximate Solution of First-Passage Problem
The first-passage time probability is approximated for Markovian processes of diffusion type from the mean crossing rate of random sequences or moving averages obtained from these processes...

The Effect of Contract Wording on Inspector Liability
Design professionals should endeavor not to write burdensome or inaccurate contracts; i.e., those that inaccurately describe duties. Inspector...

Piling in Frozen Ground
Recent construction in northern regions has emphasized the need for economical and reliable foundations, particularly in areas having permanently frozen ground. In many permafrost areas...

Computer Applications in Water Resource Planning
Due to the complexity and inter-disciplinary nature of water resource planning and management, and because many of the problems are site and situation-specific, general-purpose computer...

Infrequent Earthquake Regions: Seismic Resistance
The earthquake damage experienced by electric power systems is briefly reviewed. Low cost methods for improving the seismic response of five categories of equipment damage are discussed....
