State-of-the-Art Pipe Network Optimization
Within the next decade water distribution system optimization models should become everyday tools of practicing engineers. This paper examines existing models and discusses some of the...
Optimization of Looped Water Distribution Networks
The optimization algorithm developed by G. Quindry et al. can be used to obtain a least cost pipe network for a looped water distribution system. A solution is obtained under steady state...
Pipe Network Optimization by Enumeration
The paper describes a procedure for the optimization of pipe networks which is executed entirely in the discrete pipe size/cost domain. The technique is based on exhaustive enumeration....
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...
A Review of Artificial Intelligence
This paper presents a brief history and overview of the field of artificial intelligence (AI), describes the architecture of an expert system, and discusses the logic procedures used in...
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...
Integrated Knowledge-Based Software for Flood and Water Pollution Management
The authors' aim is to develop a comprehensive city-wide system to control both flooding and pollution. This system provides information on the sewer system with regard to:...
Data Base Management Principles
The rapid growth of computing power available in desktop micro and mini computers has placed at the disposal of individual scientists and engineers a very powerful set of tools designed...
Managing a Water Control Database
The management of a Water Control Database is important to the usability of the database. Three areas of importance in the management of a database are: 1. good management practices, 2....
Computerized Operation of California State Water Project
Hydraulic and electrical schedules for the California State Water Project are determined and dispatched from the Project Operation Control Center (POCC) in Sacramento. The dispatched schedules...
Modeling Water Resources Systems for Water Quality
A reservoir system analysis computer model has been recently developed with the capability to simulate up to 10 reservoirs, 30 control points and 8 water quality parameters. With this...
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...
A Methodology for Optimal Network Design
A methodology is developed to optimize the design of water distribution networks using reduced gradient techniques with a network simulator. The problem is reduced in complexity by incorporating...
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...
Program Monitoring by Database Management
Management of the water resources programs of the Army Corps of Engineers, with its 3 billion annual budget, 27,000 employees, and decentralized organizational structure, is obviously...
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...
Legal Constraints on the Transport of Water
Legal constraints on water transport are based on legitimate concerns for protecting the future interests of the area of origin, but such constraints sometimes appear overly restrictive...
Forecasting Water Use: A Tutorial
In spite of 4,000 years of public water supply system construction, designs have been customarily based on forecasts of future water use only during the last 100 years. Choices among available...
EPA Supported Wasteload Allocation Models
Modeling is increasingly becoming a part of the Wasteload Allocation Process. The US EPA provides guidance, technical training and computer software in support of this program. This paper...
