- You will not be able to switch off any of the default flow components from the primary drainage links (e.g., pipe flow, weir flow etc). This ensures that all default flow components are always routed downstream (so water does not disappear!). You will not be able switch on any of the non-default outflow components via the primary drainage links (e.g., infiltration, reuse, ET etc). These non-default flow components can only be added via the secondary drainage links.
- Any of the available flow components can be added and removed via secondary drainage links. MUSIC will ensure that only one flow component is shared between all outflow links for a particular node. So, for example, if you add "Pipe flow" to a secondary link it will be removed from the primary drainage link.
Creating nodes and links
There are a few simple rules which you should be aware of in creating nodes and links within MUSIC:
- Source nodes must be between 0.01ha and 10,000ha (ideally the lower limit of source node area should be 1ha).
- Realistic bounds on size and other design parameters are also specified for treatment nodes.
- Drainage links can be specified with or without routing (specified using the Edit Properties menu-item in the context-sensitive menu for that node). Additional rules regarding the creation of primary and secondary drainage links can be found here.
