                                             7.0 MUSIC Modelling Guidelines
                                             These guidelines provide instruction to the creation and application of a treatment
                                             node for the Ecosol™ Litter Basket for the Model for Urban Stormwater Improvement
                                             Conceptualisation (MUSIC). The Ecosol™ Litter Basket can be modelled in MUSIC
                                             using the Generic Treatment node to represent the results derived from independent
                                             laboratory testing and field testing by the University of South Australia and the
                                             University of Adelaide (ENGTEST The school of civil, environmental and mining
                                             engineering). The guidelines apply to the creation of the treatment node within
                                             MUSIC v6.0.4

                                             Insert a GPT treatment node into your model by selecting “GPT” under the treatment
                                             nodes menu. When the node is created the node properties dialog is displayed.
                                             There are several changes that need to be made in this dialog.

                                             • Adjust the text in the Location box to read "Ecosol™ Litter Basket" plus any other
                                               relevant information (200µm or 1500µm).
                                             • Adjust the low flow bypass to refect any flow (m3/sec) diverted away from the
                                               unit before treatment (usually zero).
                                             • Adjust the high flow bypass to reflect the treatable flow rate (TFR values are
                                               detailed in page 6) (L/Sec) any higher flows will bypass treatment
