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...

An Assessment of Environmental Costs Associated with Crude Oil Pipeline Damage Caused by Earthquakes
This paper presents a methodology for assessing the risk of environmental contamination from oil pipeline leaks caused by earthquakes. Risk is measured both as volume of oil released and...

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....

HOV Lessons
As traffic congestion worsens, transportation planners are struggling to squeeze out every last bit of available roadway capacity. High-occupancy vehicle lanes are one solution, but aren't...

Out with the Old
When the Sunshine Skyway Bridge over Tampa Bay, Fla., was partially destroyed in an accident twelve years ago, officials at the Florida Department of Transportation decided to replace...

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...

Screening Old Offshore Platforms: Previous Approaches and Further Thoughts
Several possible levels of analysis are identified, each leading to both quantitative (economic) and subjective (human) risk evaluations. These range from ratings based only on historical...

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...

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...

Boston's City within a City
The Massachusetts Water Resource Authority's 11-year effort to clean up Boston Harbor is in full swing. The nerve center of the project is Deer Island, a 210 acre site that...

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...

Waterfall Aeration Works
When they sought an alternative for instream aeration in Chicago's Calumet Waterway System, engineers at the Metropolitan Water Reclamation District of Greater Chicago (MWRDGC)...

Small Utility GIS
Geographic information systems are revolutionizing much of the civil engineering field, providing engineers and managers with a new tool to relate databases and maps. But despite the benefits...

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...
