Failure Analysis of a Buried Pipeline Transporting Gas
(American Society of Civil Engineers, 2012)The purposes of this study are to present a general analysis for the failure of a buried steel pipeline and to apply the results to a case study. Energy methods and classical beam theory are employed to model the pipeline ... -
Discoloration Material Accumulation in Water Distribution Systems
(American Society of Civil Engineers, 2011)Despite a significant ongoing investment in asset renewal and rehabilitation and high compliance rates for drinking water quality standards, water companies continue to receive customer contacts relating to water quality, ... -
Prioritizing Water Main Renewals: Case Study of the Denver Water System
(American Society of Civil Engineers, 2011)The condition of a water distribution system has strong correlations with community health and economic development. However, studies indicate an urgent need to upgrade the nation’s aging and deteriorating distribution ... -
Dynamic Deterioration Models for Sewer Pipe Network
(American Society of Civil Engineers, 2011)One of the key components in successfully implementing asset-management programs is to have accurate and reliable deterioration models for the assets because the deterioration models are the core computational basis for ... -
Sewer Blockage Management: Australian Perspective
(American Society of Civil Engineers, 2011)The functions performed by sanitary sewers can be disrupted by blockages in the pipeline, especially in cities with aging systems and deteriorating pipes. The problem is acute in Australia, where the principal blockage ... -
Thermoplastic Pipe Deep Burial Study in Ohio: Further Analysis of Field Performance Data
(American Society of Civil Engineers, 2011)In 2002, the Ohio Research Institute for Transportation and the Environment completed one of the most comprehensive field studies ever undertaken on thermoplastic pipes, involving 18 instrumented test pipes in a variety ... -
Novel Approach in Pipe Condition Scoring
(American Society of Civil Engineers, 2011)A major challenge in sewer and water pipe infrastructure management is determining structural condition scores for pipe assets. The methodology used to determine the condition of pipes should be relevant, repeatable, and ... -
Tribute to Dr. Reynold K. Watkins: Pioneer in Pipeline Technology Advancement
(American Society of Civil Engineers, 2011) -
Pipeline Dredge Analytical Program with Comparison to Field Data
(American Society of Civil Engineers, 2011)A clear understanding of pipeline dredge production capacity provides dredge operators and dredging project planners with the capability to accurately and effectively determine a project’s cost and duration. Dredge pump ... -
Maxi-HDD Pull Loads for Nonlevel Grade for Polyethylene Pipe
(American Society of Civil Engineers, 2011)ASTM -
ANFIS-Based Approach for Predicting the Scour Depth at Culvert Outlets
(American Society of Civil Engineers, 2011)The processes involved in the local scour at culverts are so complex and that makes it difficult to establish a general empirical model to provide accurate estimation for scour. This paper describes the use of adaptive ... -
Pipeline Alignment Optimization: Automated GIS-Based Approach
(American Society of Civil Engineers, 2011)The shortest route from home to work may not be the best alternative, and a longer route may be fastest or safest. Hence, the best route reflective of one factor may not be the ultimate best alternative. This paper discusses ... -
Integrating Global Positioning System with Laser Technology to Capture As-Built Information during Open-Cut Construction
(American Society of Civil Engineers, 2010)The construction industry is continuing to face the challenge of properly identifying existing underground utilities prior to engaging in new construction or renovation projects. Contractors need to know the precise location ... -
Biodeterioration of Concrete Sewer Pipes: State of the Art and Research Needs
(American Society of Civil Engineers, 2011)Biodeterioration of concrete sewers is a common problem that results in concrete disintegration and significant damage. Two stages are normally identifiable in the process: an initiation stage, during which the concrete ... -
Rational Design of a Pump-Sump and Its Model Testing
(American Society of Civil Engineers, 2011)Water pumps used in pumped storage plant, drainage, agriculture, and industrial process experience operational problems such as vibration, impeller damage, and wear of bearing caused by nonaxial inflow of water in the ... -
Gene-Expression Programming for Sediment Transport in Sewer Pipe Systems
(American Society of Civil Engineers, 2011)Old sewerage systems were designed based on empirical rules to minimize sediment problems and a list of codes for self-cleansing sewers. These codes were applicable to noncohesive sediments (typically storm sewers). This ... -
Criticality Analysis of Water Distribution Pipelines
(American Society of Civil Engineers, 2011)An approach to evaluate the relative criticality of different pipes in a water distribution system is presented. To quantify the relative criticality of pipelines, a term, relative criticality index (RCI), has been defined ... -
Pipe Efficiency Analysis at a Water Utility
(American Society of Civil Engineers, 2011)A water utility company has many actions and decisions to take in order to run operations efficiently and effectively. One of them is to decide which types of pipe(s) to install as they do not all perform the same. Because ... -
AC Pipe in North America: Inventory, Breakage, and Working Environments
(American Society of Civil Engineers, 2010)Asbestos cement (AC) pipe constitutes a significant portion of the water distribution pipes still in service in many North American cities. To understand the state of the AC pipe inventory in North America, a survey was ... -
Kalman Filtering of Hydraulic Measurements for Burst Detection in Water Distribution Systems
(American Society of Civil Engineers, 2011)Automatic burst and leak detection in water distribution systems plays an important role in water saving and management. This research develops a novel burst detection method of using adaptive Kalman filtering on hydraulic ...
