Would it be possible to have an Irregular Culvert Unit...?
Old culverts are often irregular in shape and the modeller has to model them approximately (often by picking the closest regular shape - or trying to come up with a shape which has the same area/wetted perimiter). This is fiddly and time consuming.

At the moment the closest we have to an Irregular Culvert Unit is the Symmetrical Conduit unit. This unit allows you to have the Irregular shape - but left and right hand sides must be the symmetrical.

I know this is a problem in other well known 1D hydraulic modelling packages too - so implementing this would give ISIS an advantage...
