Pf. Boulos et al., DISCRETE SIMULATION APPROACH FOR NETWORK-WATER-QUALITY MODELS, Journal of water resources planning and management, 121(1), 1995, pp. 49-60
An efficient system simulation methodology that solves the contaminant
-transport problem in drinking-water-distribution systems is developed
. The method can be effectively used for modeling the time-varying int
eraction of water quality and hydraulic behavior within the distributi
on-system environment. The solution of the time-varying water-quality
problem is obtained in an event-oriented system-simulation framework.
This allows for dynamic water-quality modeling that is less sensitive
to the structure of the network and to the length of the simulation pr
ocess itself than previously proposed methods. In addition, numerical
dispersion of concentration front profile resolution is nearly elimina
ted. The resulting method can be applied to every type of water-distri
bution system while requiring the least number of calculations necessa
ry to carry out the simulation process. The performance of the method
is demonstated by application to an example water-distribution network
. The method should prove to be a valuable tool for managing water qua
lity in drinking-water-distribution systems.
