Seattle Plays It Safe
To ensure the reliability of its aging water system in a major earthquake, the Seattle Water Department commissioned a comprehensive assessment of the system's seismic reliability...
Migration of Spilled Oil from Ruptured Underground Crude Oil Pipelines in the Memphis Area
This study evaluated the impact of an oil pipeline rupture in the recharge area of a West Tennessee aquifer. Two potential break locations were chosen in the alluvial valley of a main...
The Superposition Approach to Pile Group Dynamics
A general three-dimensional boundary integral formulation for pile groups is used to obtain a set of dynamic interaction factors for a number of soil profiles and for a wide range of pile...
Dallas Goes Trenchless
Dallas Water Utilities (DWU) has stopped relying solely on traditional open-cut trenching methods. Instead, we look to trenchless technologies to minimize costs and disruption to the public....

A Numerical Study of Kinematics of Nonlinear Water Waves in Three Dimensions
We present a new method for analyzing the kinematics of nonlinear water waves in a three-dimensional domain. This method is based on our extension and generalization of the mixed-Eulerian-Lagrangian...
A Simple Method to Compute Wave Loads on a TLP
In this paper, analytic diffraction (Linton and Evans, 1990) and radiation (Kim, 1992) solutions for arrays of bottom-mounted vertical circular cylinders are used to compute hydrodynamic...
Computer Aided Design for Deep Water Offshore Risers
This paper describes a software package (OTRC-Riser-91) that was developed under the sponsorship of the Offshore Research Technology Center that is funded by the National Science Foundation...
Sea Floor Wave-Induced Water Kinematics for Design of Pipeline
A statistical model is presented for horizontal velocity and acceleration of water particles beneath storm seas near the sea floor. An expansion of the kinematics with basis functions...
Spectral and Statistical Characteristics of Wind Waves Off Canary Islands
Wave climate around Canary Islands is studied by means of statistical and spectral techniques. Maximum Entropy Method is used for obtaining the spectral density function. Autocorrelation...
Effects of Freezing on Impact Properties of RTM Composites, and Their Applications in Offshore Structures
Resin transfer molding is rapidly being acknowledged as the process with potential to create perhaps the purest form of a composite material as representative of the concept of `material-by-design.'...
Internationalization of Engineering Professions
The most salient features impacting the development of our deepwater frontier areas are considered. The areas of higher potential for deepwater reserves are identified. The integrated...

Utilization of Waste Materials in Civil Engineering Construction
Industrial growth has increased the volume of wastes generated from energy production, mining, industrial processes and civil works. For economic and related reasons, the use of waste...
RCC at 10
Tens years after the first roller-compacted concrete (RCC) dam in the U.S.�the 169 ft high Willow Creek Dam in Oregon�was completed, the method has gained wide acceptance around the world...
Instrumenting the `Y'
Segmental bridges are still relatively new to the U.S. and questions persist about their design and behavior. To expand the knowledge base, a number of laboratory and field studies have...
Put to the Test
In the construction industry, the concept of life-cycle cost applies not only to the infrastructure itself, but to the materials that go in to building that infrastructure. To improve...
Settling Down Easy
In order to more fully participate in the international and Asian Pacific aviation network, it was decided to establish a highly efficient 24-hour a day operation at the New Kansai International...
Underground Research: Here and There
Geotechnical research in Europe, Japan and the U.S. were compared in a study funded by the National Science Foundation. Visits to research facilities and several surveys resulted in two...
Rethinking the Competitive Bid
Concern that the U.S. construction industry is losing its competitive edge is nothing new. Ironically, the problem is not so much rooted in foreign technical expertise as it is in our...
