Water Distribution Design with Multiple Demands
An iterative procedure for the layout and design of new looped water distribution systems is pesented. The procedure is also applicable to the expansion of existing systems. The approach...
Diagnosis of Wastewater Treatment Processes
This paper presents an approach to the development of an expert system for aiding the operation of an activated sludge wastewater treatment facility. The expert system incorporates a diagnostic...
Practical Optimization of Looped Water Systems
This paper describes one tool that might be part of a package to assist a design engineer in sizing pipes, determining ideal locations for booster pumps and their heads, determining heads...
OPNET: A Nonlinear Design Algorithm for Hydraulic Networks
The author has developed a general computer program OPNET to be used in the optimal design of hydraulic networks. The computer program can be used to optimize three basic variables; tank...
Integrated Operation of the Ottawa River System
Several years ago, an integrated operating process was developed in response to specific problems on the Ottawa River. The operating process involves several public-sector organizations...
Computerized Design and Selection of Pumping Systems
Three computer models have been applied in the evaluation, design and selection of a high-lift pump station upgrading program developed for the City of Poughkeepsie, New York. The three...
Integrated Design Methodology for Urban Stormwater Detention Facilities
The objective of this paper is to present the core of a design methodology that avoids the pitfalls of the design storm concept by using a microcomputer algorithm to estimate the long-term...
Computer Aided Design Using CORPS
The Hydraulic Analysis Division, Hydraulics Laboratory, US Army Engineer Waterways Experiment Station (WES) has the responsibility for developing and disseminating hydraulic guidance for...
Conceptual Framework for Regression Modeling of Ground-Water Flow
The author examines the uses of ground-water flow models and which classes of use require treatment of stochastic components. He then compares traditional and stochastic procedures for...
Numerical Modeling of Groundwater-Lake Systems
Groundwater inflows can have important effects on the chemistry and biology of a lake ecosystem. For example, studies of lakes in Northern Wisconsin documented localization of ferromanganese...
Risk-Cost Analysis and Spillway Design
The NRC's recent report on dam safety proposes risk cost analysis to help select among alternative spillway modifications for existing dams. This paper examines the sensitivity...
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...
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...
Understanding Secondary Clarifier Behavior
The author has developed a graphic procedure for analyzing the hydraulic behavior of settling tanks. Data have been used in numerous cases to devise low cost in-tank and external improvements...
Optimization of Variable Volume Diaphragm Filter Presses
The St. Paul, MN, Metropolitan Waste Control Commission Wastewater Treatment Plant has installed and operated eight variable volume diaphragm filter presses for four years. During this...
Structural Safety Studies
Structural engineers are most concerned with the safety aspect of structures. The primary objective of structural engineers is to produce structures which are satisfactory in meeting certain...
Seepage and Leakage from Dams and Impoundments
All major dams and impoundments are usually analyzed to determine the magnitude and location of seepage that can occur under, around or through the structure. More often than not, seepage...
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...
Optimization Issues in the Design and Control of Large Space Structures
