Powering Your Electric Vehicle: Affordability Starts with Properly Engineered Geomembrane Liner Systems
Lithium is a vital battery component, and lithium-ion batteries are especially interesting because in addition to being rechargeable, they present a high-energy density and low self-discharge, which means...
Seepage and Transport through Anaerobic Lagoon Liners
In this chapter, the seepage and transport characteristics of lagoon liners are addressed using the soils and hydrogeology of southwest Kansas as examples....
Clogging of Animal Waste: An Overview
This chapter examines research addressing the mechanisms that play a role in the clogging of lagoon liners by animal waste....
Use of Coal Combustion By-Products as Low-Permeability Liners for Manure Storage Facilities
This chapter presents an overview of the use of compacted flue gas desulfurization (FGD) material as a low-permeability liner. It discusses the engineering characteristics of FGD materials...
Advancing Under London
Bored tunnels account for more than 20 percent of the Channel Tunnel Rail Link, the high-speed rail line that will connect the Channel Tunnel with London upon its completion in 2007. In...
Update of ASCE Manuals and Reports on Engineering Practice No.74 Guidelines for Electrical Transmission Line Structural Loads
For many months there has been doubt that the latest version of ASCE Manuals and Reports on Engineering Practice No. 74. Guidelines for Electrical Transmission Line Structural Loading,...
Effect of Aluminum Compression on ACSR Conductor Sags at High Operating Temperatures
Deregulation and restructuring are sweeping the electric utility industry in the United States. As a result, many utility engineers are analyzing, re-rating, and upgrading their most critical...
Use of New Liner In Water Distribution System
For years there has been interest in rehabilitation of water distribution systems to provide quality drinking water and to reduce breaks in the water system service. Much work has been...
Monitoring Two Tunnels
Two pilot projects for bored tunneling in soft soil have been undertaken in the Netherlands under the authority of the Centre for Underground Construction: the Second Heinenoord Tunnel...
Pushing Back
(Available on in special edition) The design for the $3.5-million Cameron Run tunnel rehabilitation project involved a tricky and relatively unproven method of pushing corrugated steel...
Liner Lessons
The County Sanitation Districts of Los Angeles County comprise 25 independent special districts that cover a service area of approximately 770 sq mi (1,990 km�). Since the early 1990s...
Stretching a Landfill
Landfill expansions can pose engineering challenges, and the Tullytown, Pa., landfill gives an example of a horizontal expansion that added 121 acres of future disposal space. The side-by-side...
Cure for Thinning Concrete
After placing 75% of the concrete liner for twin 4.6 km transit tunnels in Portland, Ore., engineers discovered areas of concrete that were thinner than the prescribed 305 mm thickness....
Putting On Your Safety Cap
Geomembranes are an important part of landfill cap design. However not all geomembrane liners are created equal, and it's best to know what a liner is made of before specifying...
Florida's Big Bellies
FPL designed and installed double reverse tapered poles, affectionately called big belly because the width gradually increases toward the middle and narrows at both ends. The poles replace...
Plumbing the Quality of a Sewer System
Consultants in Phoenix were recently charged with assessing the city's sewer system, many feet of which were laid without plastic lining to protect them. Developing a capital...
Detecting Leaks Electronically (Available only in Geo/Environmental Engineering Special Issue)
An innovative monitoring system originally developed to detect cyanide leaks at gold mines can now monitor the integrity of geosynthetic liners at municipal- and hazardous-waste landfills...
Flexible Membrane Liners
Unless there is a long-range plan for the postclosure use of a landfill--such as turning it into a golf course or a park--final grades are usually designed to be as high and as steep as...
Optical Waveguide Solar Energy System for Lunar Material Processing
This paper summarizes a study of the optical waveguide (OW) solar energy system for lunar material processing. In the OW solar energy system, solar radiation is collected by the concentrator...
Overview - Electrical Substation Structures Design Guide
The ASCE Substation Structures subcommittee of the Committee on Electrical Transmission Structures (CETS) is developing a substation structures design guide. The guide discusses the analysis...
