Parameters to specify:
Length, Slope, Manning's n, Height, Side Slope, see Connection Inputs.
Upstream (US) Cover Level, Upstream Invert Level, Downstream (DS) Cover Level and Downstream Invert Level. see below.
If the Slope or Downstream Invert Level are changed by the user, the other variable will be updated to match.
If the Height or Upstream Invert Level are changed by the user the other variable will be updated to match.
Where possible connection levels are automatically set from Surface data, existing Stormwater Controls and existing Junctions. This is done following the rules below but can be overruled by the user. Where levels have been overruled by the user or by the Pipe Sizing procedure the values will be shown in red to indicate they are no longer following the rules below and will not be automatically updated.
