Impact of Current Regulations on Geotechnical Practice
Enactment of the Resource Conservation and Recovery Act (RCRA), which was intended to provide 'cradle to grave' management of hazardous waste, has caused a greater...
Hydrocarbon Refining Waste Stabilization for Landfills
Mobile pollutants are generated in a landfill as a function of the waste properties and the response of the deposit to the in-situ stress, climate and biochemical conditions. Release of...
Stabilization of FGC Wastes
Presently, flue gas cleaning (FGC) wastes (scrubber sludges and flyash) are produced in large quantities, with future production likely to increase as utilities install additional stack...
Temporary Structures in Construction Operations
Temporary works have a primary influence on the quality, safety, speed and profitability of all construction projects. They provide access, support and protection of a facility under construction....
Energy Solutions Today for the Nineties
Optimal use of energy resources requires intelligent planning by all segments of society, especially the technical disciplines. Civil engineers play a key role in developing energy resources...
Infrastructure
Repairs and Inspection
Rehabilitation of a structure in general requires considerations of unique methods of inspection and repair. Since the structures have to remain in service while the repairs are done,...
Making Embassies Safe for Democracy
American interests overseas have become among the most popular targets for terrorist attacks. Once, not long ago, security was only an afterthought for such facilities. Today, $4.4 billion...
Quake Resistant Transport
An approach which begins by assessing the vulnerability of a transportation system's key components can help transportation engineers plan for and limit earthquake damage....
Historic Bridges: Conflict Ahead
The engineer who deals with historic bridges becomes the focus of controversy in the course of determining the existing condition, predicting remaining useful life, and designing the repair...
Little Bubbles, Big Payoff
Fine poor diffusers often boost the energy-efficiency of aeration in sewage plants by 25-50%. This is important because the combined energy bill of all U.S. municipal sewage plants is...
Risk Assessment and Public Policy
A governmental official charged with making solid waste policy should be careful not to allow the public policy issue to be defined as the determination of the acceptable level of risk...
Wastewater Technology Innovation for the Year 2000
The present state of wastewater technology research is on a decline because of shrinking funds. A national effort by professionals in all sectors of the wastewater establishment is encouraged...
Electronic Gymnastics
Efforts are being made to have all the parties to a project share the same, current information. In order to do so, civil engineering firms are jumping through electronic hoops to get...
Computer Scheduling: On-Line and On-Time
The Intermountain Power Plant, a coal fired, 761 MW coal fired electrica generating facility, has been completed months ahead of schedule and substantially under budget. Project managers...
Predicting Equipment Failure
At Cleveland's Westerly Water Pollution Control Center, the physical/chemical plant for treating wastewater is one of the largest of its kind, with 50 mgd average capacity....
Computers: What Do Students Need to Know?
This article is based on interviews with three professors at three universities, a recent graduate from each school, and the graduate's employer. The interviews show that...
Expert Systems for Risk Analysis
An explanation is presented on why construction risk analysis can be handled by an expert system computer program. The author offers a prototype construction risk management expert system...
Irrigation Water Management with Rotation Scheduling Policies
Rotation schedules are delivery-system oriented and represent relatively low capitol investment in system components and system management, but are not usually responsive enough to crop...
System Scheduling for Large Farming Operations
Irrigation scheduling uses evapotranspiration data to recommend the time and amount of the next irrigation on a field by field basis. System scheduling minimizes the cost of water deliveries...
Demand Irrigation Schedules
This class of schedules consists of Demand and Limited Rate Demand. They need no communication system and can satisfy the on-farm needs with negligible constraint. The Demand schedule...
