3.3. EPANET MSX
Chlorine modeling with EPANET MSX is not as practical as standard EPANET 2.0, given the lack of a
graphical user interface. It requires MS-DOS user capabilities and it does not allow for rapid visualization of
results. In addition, calibrating a wall decay rate coefficient with MSX extension can be quite a time-consuming
and complex task. Epanet Java was faster and more effective to use due to the innovative use of its 3-D graphical
interface and integration with Google Earth®. It allowed for immediate visualization of results of chlorine decay
simulation with the 2R model (Figure 4).
