IDENTIFICATION OF CONTAMINANT SOURCES IN WATER DISTRIBUTION SYSTEMS USING SIMULATION-OPTIMIZATION METHOD : CASE STUDY

In this paper, the authors propose a new approach, the simulation–optimization method, to solve a nonlinear contaminant source and release-history identification problem for a complex water distribution system. This approach is based on optimization analysis, using the EPANET water distribution system model as a simulator. In this approach, EPANET is used to generate concentrations at arbitrarily selected monitoring locations by specifying release histories of potential contaminant sources that are arbitrarily located within the water distribution system.
