Hydraulic Profile Computation Using CADD
The data preparation can also be performed by directly recording onto a computer tape the aerial survey cross section ground points and the field survey work. A computer program can then...
Setup and Usage of Multitasking Microcomputers for Water Management Problem Solving
Software and hardware that were developed in the evolution of the microcomputer from the Altair to today's state of the art multitasking systems are discussed. The rationale...
Hydrologic Work Group System Using Distributed Task Processing
The notion behind work group systems is that a collection of co-workers, numbering from a few to a few tens of people, is the logical unit around which to build a centralized microcomputer...
Computer Control of Lift Station Operations
A unique computerized control system to supervise the operation of several lift stations has been designed by Boyle Engineering Corporation (Boyle) and constructed by the City of Orlando,...
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...
Wetland Protection Regulations: A Technical Perspective
This paper summarizes the technical basis for the application of wetland protection regulatory schemes upon a number of typical environmental engineering and related projects. A number...
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....
Saving Time and Money with Archaeology
In the past 20 years, archaeology has become a necessary part of many engineering projects. However, this aspect of a project is often regarded as an obstacle in terms of costs and time....
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...
Environmental Infrastructure: Does Civil Engineering Education Meet the Challenge?
The author explores some avenues for re-direction of the civil engineering education process to become more responsive to the needs of infrastructure re-development in the areas of water...
A Stepwise Approach to Environmental Systems Maintenance Management
This paper provides a systematic approach to establishing a maintenance management program for environmental infrastructure. It begins by discussing the definition of program objectives,...
Health Effects Evaluation?Ocean Disposal of Sludge
Court rulings have recently allowed the ocean disposal of municipal wastewater sludge in certain cases. This paper describes a methodology which was developed to determine acceptable loadings...
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...
