In addition to substance concentrations, water age and source tracing can also be simulated. The program can compute a simultaneous solution for both conditions together. Alternatively it can compute only network hydraulics and save these results to a file, or use a previously saved hydraulics file to drive a water quality simulation.
Reaction can occur both within the bulk flow and with material along the pipe wall.
Bulk fluid reactions can also occur within tanks. Different values for Kb can be used for different pipes and tanks in the network and the same holds true for Kw. These coefficients are positive for growth reactions and negative for decay reactions. Links and nodes are identified with ID numbers and can be arranged in any fashion. Sampling program design, hydraulic model calibration, chlorine residual analysis, disinfectant loss and by-product formation study, and consumer exposure assessment are some examples.
