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...
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...
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...
Practical Water Demand Forecasting
The authors describe their experience in designing, building, and applying a water demand forecasting model for the Denver metropolitan area. In the presence of incomplete and sometimes...
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...
Future Trends in Software Development
The Office of Water (OW) has set program goals of improving the productivity and technical quality of wasteload allocation modeling and water quality-based permitting in the States and...
Tampa Bay 205J Water Quality Impact Study
Tampa Bay was identified by the State of Florida Department of Environmental Regulation (FDER) as to the top priority for an impact study using federal 205(j) grant funding. The study...
Optimizing Nonpoint Source Pollution Reduction Costs
This study demonstrates diminishing marginal returns for spending to reduce nonpoint source pollution in Hampton, Virginia. A linear optimization program selected the best combination...
