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
