== How can a flow splitter with a nib wall be modelled? ==

 

A flow splitter with a nib wall can be modelled by introducing a 1D weir between the manhole and the relevant outlet pipe. The weir crest elevation should be set equal to the height of the nib wall within the chamber. This setup allows low flows to discharge through one pipe, while higher flows overtop the weir into a secondary outlet, replicating the behaviour of a physical flow splitter.

 

Refer to the schematic example below for this configuration.
