Friction Losses in Large-Diameter Pipes
(American Society of Civil Engineers, 2015)There is evidence in literature that friction factors -
Demonstration and Evaluation of State-of-the-Art Wastewater Collection Systems Condition Assessment Technologies
(American Society of Civil Engineers, 2014)Condition assessment of wastewater collection systems is a vital part of a utility’s asset management program. Reliable information on pipe condition is needed to prioritize rehabilitation and replacement projects, given ... -
Decision Analysis of Preferred Methods for Locating Underground Conduits
(American Society of Civil Engineers, 2014)The New Jersey DOT (NJDOT) operates and maintains a network of thousands of kilometers of conduits, many carrying fiber-optic cables that are vital to the state’s communication system. These primarily nonmetallic conduits ... -
Simulation of Behavior of In-Service Metal Culverts
(American Society of Civil Engineers, 2014)As part of an experimental program, a large number of in-service culverts were tested to investigate the influence of several parameters on field performance of culverts. These parameters included cover depth, load ... -
Construction Monitoring of a Municipal Gas Pipeline during Horizontal Directional Drilling
(American Society of Civil Engineers, 2013)Horizontal directional drilling (HDD) is an important technology for the placement of municipal pipelines, including water and sewer lines. This paper describes the in situ monitoring of the installation of a gas pipeline ... -
Tribute to Lynn Osborn, P.E., M.ASCE: An Industry Leader
(American Society of Civil Engineers, 2013) -
Gene Expression Models for the Prediction of Longitudinal Dispersion Coefficients in Transitional and Turbulent Pipe Flow
(American Society of Civil Engineers, 2014)Longitudinal dispersion in pipelines leads to changes in the characteristics of contaminants. It is critical to quantify these changes because the contaminants travel through water networks or through chemical reactors. ... -
Evaluating Fitness-for-Service of Corroded Metal Pipelines: Structural Reliability Bases
(American Society of Civil Engineers, 2014)This paper presents a methodology for evaluating fitness-for-service (i.e., safety, serviceability, and reliability) of corroded metal pipelines. A model for predicting pipe failure pressure is developed from a series of ... -
Analysis of Cross-Bores in Unmarked Sewer Service Laterals
(American Society of Civil Engineers, 2014)With an increase in trenchless methods being used for the installation of natural gas lines in urban areas, unmarked sewer service laterals present a risk of accidental and unknown cross-bores with these distribution lines. ... -
Optimal Design of Pumping Mains Considering Pump Characteristics
(American Society of Civil Engineers, 2014)The total cost of a pumped water supply system includes the capital costs of the pipeline and pumping units, the replacement costs of various components included, and the energy costs related to the system’s operation. The ... -
Modification of Hunter’s Curve in the Perspective of Water Conservation
(American Society of Civil Engineers, 2014)Plumbing-system designers, who routinely use Hunter’s curve for estimating domestic demand, actually solve complex problems based on the probabilistic approach. Recently, serious questions have arisen about the accuracy ... -
Integer Discrete Particle Swarm Optimization of Water Distribution Networks
(American Society of Civil Engineers, 2014)The integer discrete particle swarm algorithm is used as an optimization technique for the design of water distribution networks in order to minimize its total cost. Because the particle swarm is highly sensitive to its ... -
Vertical Uplift Resistance of Pipes Buried in Sand
(American Society of Civil Engineers, 2014)By incorporating the variation of peak soil friction angle ( -
Modeling Deterioration in Concrete Pipes as a Stochastic Gamma Process for Time-Dependent Reliability Analysis
(American Society of Civil Engineers, 2014)Concrete sewer pipes encounter corrosion as a predominant form of deterioration that reduces the service life of the pipeline system and increases the costs of maintenance and rehabilitation. Reliability analysis can help ... -
Discussion of “Genetic Programming to Predict River Pipeline Scour” by H. Md. Azamathulla and Aminuddin Ab Ghani
(American Society of Civil Engineers, 2013) -
Maxi-HDD Pull Loads for Entry and Exit Points at Different Elevations
(American Society of Civil Engineers, 2015)ASTM guidelines provide a procedure for estimating pull loads and stresses on polyethylene pipe as primarily a function of the drilled path and buoyant weight of the pipe in the drilled hole. The equations were initially ... -
Response of Underground Pipelines Subjected to Partially Coherent Seismic Excitation
(American Society of Civil Engineers, 2013)Analyses on the basis of seismic array records have confirmed that spatially distributed earthquake ground motions are neither fully coherent nor independent, but partially coherent. It has not yet been fully addressed how ... -
Water Main Breaks: Risk Assessment and Investment Strategies
(American Society of Civil Engineers, 2013)Replacement to sustain the integrity of water mains in the United States is on a cycle of approximately once in 200 years, a slow rate that contributes to the current grade of D- on the Infrastructure Report Card. The main ... -
Modeling the Effects of Backfilling and Soil Compaction beside Shallow Buried Pipes
(American Society of Civil Engineers, 2013)Compaction of the soil placed beside culverts (the side-fill) can have a significant effect on the behavior of flexible and rigid structures. This is particularly true for shallow buried structures when the stresses resulting ... -
Experimental Investigation of Longitudinal Bending of Buried Steel Pipes Pulled through Dense Sand
(American Society of Civil Engineers, 2014)North America is traversed by many high-pressure oil and gas transmission pipes and the stability of that essential buried infrastructure must be maintained under a variety of earth-loading conditions. In the research ...
