New Pavement from Old Concrete
Recycling portland cement concrete has gained momentum as an alternative to resurfacing aging highway and airfield pavements. Recycling cuts down rawmaterial requirements, reduces the...
Building on Muck
The Craney Island Disposal Area at Norfolk, Va. is a 2,500 acre depository for material dredged from ports and channels in the Hampton Roads. The U.S. Army Corps of Engineers extended...
Personnel Policies for Operations Management in the Computer Age
The human factor is an essential ingredient and the key element in successful computer applications for water resources or any other field. Engineers in general, and engineering managers...
A Riverine Toxic Spill Model
In the event of a spill of toxic material reaching the main stem of the Potomac River, predictive information regarding its location and concentration would aid in the minimization of...
Fluidization of Biomas Covered Sand Particles
The expansion behavior of the fluidized bed reactor support medium is important in its design and analysis. Steady state and dynamic behavior of fluidized bed expansion were compared with...
Modular Plastic Media for Shallow Bed Trickling Filter Applications
Little specific data is available for less sophisticated trickling filter systems which employ recent plastic media designs for shallow bed filters without the added cost of subsequent...
Method Development for Evaluating Radionuclide Emissions from Incineration of Low Level Radioactive Waste
The implementation of an incineration monitoring program for low level radioactive waste is a complex task, especially in the area of obtaining environmental permits. Emissions monitoring...
Direct Filtration of Colored Water Supplies
The effects of raw water quality, chemical treatment, and filtration variables on the performance of direct filtration are examined. Cationic polyelectrolytes as sole coagulants are effective...
Optimization of Design and Operating Parameters for Single-Media, Unstratified-Bed Filters
The potentially successful use of filters containing large grain-size single media for water filtration has prompted investigation of the parameters controlling the performance of these...
Age-Specific Cancer Risk Analysis for a Population Exposed to Contaminated Drinking Water
Recent developments in the methodology for estimating cancer risk for environmental contaminants exhibit promise for improved predictability of risk analyses based on EPA risk guidelines....
A Study of River Foaming and its Possible Causes
Foaming has been observed on uncontaminated upland streams draining watersheds having no human related development. Because water alone will not foam when agitated, the presence of these...
Design of a GAC Water Treatment System for Radon
The author describes the design of a granular activated carbon (GAC) treatment system for the removal of radon from a public water supply....
Issues in Dam Grouting
Although perhaps the largest number of individual grouting projects do not involve dams, by far the largest volume of grout used is for grouting of new or existing dams. This volume presents...
Roller Compacted Concrete
Roller compacted concrete has emerged recently as an economical material and rapid method of construction for use in gravity dams, overflow structures and heavy duty pavements. The economics...
The Engineering Aesthetics of Tall Buildings
The Proceedings of a session on the Aesthetics and Design of High-Rise Buildings at the ASCE Convention in Denver is included in its entirety. The session was chaired by Lynn Beedle and...
The Analysis of the Environmental Impact
Oil serves mankind. Winning such a valuable and necessary energy resource demands for stringent rules. It is not the oil which threatens the environment on earth, but the negligence of...
Oil Spill Detection by NOAA/AVHRR on Persian Gulf
An area of oil spills on the Persian Gulf was detected by the thermal-infrared channels of Advanced Very High Resolution Radiometer (AVHRR) on NOAA-7. AVHRR gives the temperatures of the...
Oil Spill Risk Assessment for Marine Vessels
An oil spill risk assessment study should show the estimated relationship between the magnitude of an adverse environmental impact and the probability of equaling or exceeding that impact....
Report: Persian Gulf Conference, May, '84
The First International Conference on the Impact of Oil Spill in the Persian Gulf was held at the University of Tehran, Islamic Republic of Iran (I. R. I. ), from 20 May to 27 May, 1984....
Who's Minding the Beach?...The Virginia Experience
Virginia entered the realm of statewide funding for the enhancement of public beaches on July 1, 1980 with the creation of the Commission on the Conservation and Development of Public...
