ENVIRONMENT PROTECTION – MODELING WATER QUALITY IN DRINKING WATER DISTRIBUTION SYSTEMS
The solution of the time-varying water-quality problem is obtained in an event-oriented system-simulation framework. In case when a relatively large number of seps are simultaneously active, a partial aggregation of the seps may be performed (with Gauss formula using Legendre polynomial of tow degree). This allows for dynamic water-quality modeling that is less sensitive to the structure of the network and to the length of the simulation process itself than previously proposed method. In addition, numerical dispersion of concentration front profile resolution is nearly eliminated. The performance of the method is demonstrated by application to one example water distribution network..
