Energy Efficient Pump Station Operation with a Pump Switching Constraint
Pump operation scheduling has become a significant practical and research concern as utilities increase their computer usage. This paper presents an integer programming algorithm which...

Planning, Assessing and Implementing Pipeline Rehabilitation Options
The methods of investigation for determining pipeline rehabilitation options for design and construction are directed chiefly toward: a) cost minimization of necessary rehabilitation projects;...

Simplified Design of Multi-Stage Outfalls for Urban Detention Basins
This paper presents a simple method for designing multiple stage outlets for detention basins. The method is based on formulas which were derived for the rational and modified rational...

Site Impact Traffic Assessment
Problems and Solutions
Transportation needs have traditionally derived from land use decisions. Site impact traffic analysis is a formalized process that attempts to quantify the need for transportation improvements...

The OCEA Awards of Merit
Submerged rock weirs help tame the Mississippi River, high head pump storage provides power to a community safely and inexpensively, and the world's largest cantilevered hangar...

OCEA, American-Style
A truly All-American contingent, the nominees for this year's Outstanding Civil Engineering Achievement award span the continental U.S., Alaska and Hawaii. The scope of the...

Durability Failure of a Concrete Block Port Pavement
A concrete block port pavement began showing distress after 7.5 years of use. Initial repair attempts found extensive areas of deterioration. The concrete blocks were cracking, spalling,...

Standard Methodologies for the Forensic Investigation of Pavements
The high costs of new construction have made the preservation and restoration of existing pavements an attractive alternative to replacement structures. Existing pavements that are to...

Use of the Break-Off Method for the Evaluation of High Performance Concrete
The Break-Off test is one of the recent developments for testing in-place concrete strength. This research was undertaken to investigate the reliability of the Break-Off test as a measure...

Successful High Traffic Chip Seal Construction
Chip seal coats are used to extend pavement service life by reducing water and air infiltration and improving skid resistance. Application of chip seals is usually limited to low-traffic...

Seismic Hazard Analysis for Crude Oil Pipelines in the New Madrid Seismic Zone
The seismic vulnerability of three crude oil pipelines in and around the New Madrid Seismic Zone (NMSZ) is evaluated for a repetition of the 1811-12 New Madrid events. The seismic hazard...

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...

Earthquake Countermeasures for Lifelines in the Central and Eastern United States
Seismic hazards affecting petroleum transmission systems in the Central U.S. and water and gas distribution systems in the Eastern U.S. are discussed. Experience during previous earthquakes...

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...

Radiation Energy Treatment of Water, Wastewater and Sludge
A State-of-the-Art Report
Since ionizing radiation is one of the more technologically advanced forms of energy available to society, it has been applied to a great many activities such as: the sterilization of...

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...

Feasibility Study of Petroleum Development in the Ross Sea, Antarctica
This paper discusses the viability of Antarctic petroleum development and estimates when Antarctic oil production could become economically feasible. The analysis is based on a hypothetical...

Predicting Fate and Effects of Hydrocarbons in the Oceans
Three major sources of hydrocarbons exist in the oceans. One is from oil spills related to the production and transportation of hydrocarbons. The second, while generally not spectacular,...
