Abstract:
Identifying the precise source of delivered flow in water distribution systems is increasingly important. The necessity for this arises when individual supplies exceed allowable levels of certain chemical or biological constituents. An explicit methodology to make these calculations for complex water distribution systems is presented. The methodology requires the solution of a set of linear equations of order equal to the number of junctions. The equation coefficients are based on the flow distribution for the system demands under consideration. Because the explicit solution procedure requires the simultaneous solution of large equation sets for large networks, an alternative solution technique was developed. This technique solved the equations in a simple, cyclic manner requiring little computer storage and proved to be an efficient scheme for carrying out the calculations. During the past few decades, various each source to the demand at a particular computer models have been developed junction node. Such calculations are for use in modeling water distribution normally required because of concern systems. These models can be used to over the possible effects of one or more predict flows and pressures throughout supplies that may exceed allowable levels a particular distribution system in of various pollutants or chemicals. As a response to a given set of operating result, it may be necessary to determine conditions. In systems with multiple the percentage of flow originating at water supply sources, it may be neces- such supplies at critical points throughsary to determine the contribution of out the distribution system.
