House Handily Approves Water Resources Development Act
The House passes the Water Resources Development Act, putting pressure on the Senate to advance its water resources bill....
Review of Climate Science for Engineering Practice
Weather and climate are a factor in civil engineering design and practice. Weather is defined as the state of the atmosphere with respect to wind, temperature, cloudiness, moisture, pressure,...
Pipe Characteristics
Microtunneling pipe should meet the following general requirements: Circular shape with a flush outside surface (including at the joints); Strength sufficient to withstand both the installation...
Pipe Design
The pipes and joints, once installed, must be capable of safely withstanding, for the project design life, all in-use service loads, including those associated with the following factors:...
Performance Limits for Deepwater Pipelines
This paper highlights the differences between onshore and offshore pipeline design. It then summarizes the results of combined external pressure, tension, and bending testing on full scale...
Estimation of Consolidation Properties of Clay from Field Observations
Analyses to obtain theoretical time-settlement curves for embankments typically make use of soil properties measured in the laboratory on small disturbed samples subject to strain rates...
Behaviour of Open-Ended Pipe Piles in Sand During Installation and Loading
An experimental study was performed to investigate the physical processes which influence the axial load capacities of open-ended steel pipe piles in sand. A double-walled pipe pile was...
Pore Water Pressures in Unsaturated Soils
Unsaturated soils are three-phase systems composed of solid mineral matter, water, and air. Such soils may be formed by either natural or artificial means. Except in moist environments,...
Sinkhole Investigation and Grouting: Novel Recommendations for a Pipeline Right-of-Way
In 2009, numerous sinkholes developed within and adjacent to a 400-ft-long section of high-pressure, petroleum pipeline right-of-way that crosses under a local creek in Plymouth Meeting,...
Non-Destructive Strength Evaluation of a Continuous, Reinforced Concrete Slab Bridge
In the state of New Mexico, a significant number of reinforced concrete slab (RCS) bridges provide service on interstate highways I-10, I-25, and I-40 that are subjected to large amounts...
Application of TOPNET in the Distributed Model Intercomparison Project (DMIP)
This paper describes the application of a networked version of TOPMODEL, TOPNET, as part of the Distributed Model Intercomparison Project, DMIP. The model implementation is based on a...
Pressure Relief
When the two basins making up a 90 acre reservoir in New York needed to be emptied and cleaned, engineers decided to use the 2,750 ft (840 m) long concrete wall dividing them as a dam....
A Paradigm Shift in Irrigation Management
In coming decades, irrigated agriculture will be called upon to produce up to two thirds of the increased food supply needed by an expanding world population. But the increasing dependence...
Impact of Chemically-Induced Clay Transport and Deposition on the Hydraulic Conductivity of a Natural Sand
The purpose of this paper is to understand in part the dynamic impact of surfactants on hydraulic conductivity for designing enhanced pump and treat operations. This paper has two aims:...
Leakage Control?Finding a New Resource from the Existing One
It is estimated that by the year 2005, one person in two will have an insufficient supply of one of the world's most precious elements: water. Worse still, it is predicted that this shortage...
Control of Microorganisms in Drinking Water
Prepared by the Water Supply Engineering Technical Committee of the Infrastructure Council of the Environmental and Water Resources Institute of ASCE. ...
Deep Freeze
In engineering, overcoming a failure can sometimes be more instructive than completing a project with unqualified success. Such was the case with the collapse and repair of a force main...
Comparison of Hydrodynamic Parameters for a Floating Breakwater
The U. S. Army Engineer Research and Development Center is in the process of developing a Rapidly Installed Breakwater System (RIBS) for use in Joint Logistics Over the Shore Operations...
Quality Control Test for Prestressing Wires in Concrete Pressure Pipe
Prestressed concrete cylinder pipe (PCCP) was introduced in 1942 as a high pressure capacity conduit for water transmission. The principal element of the design and construction that imparts...
Tunnel with Vision
Two tunnel boring machines that are being used to bore a pair of 6.6 km long tunnels under the Westerschelde estuary in the southern Netherlands must dig through loose sand and sticky...
