A swale object would be swell to have!
This swale object would allow the user to specify a bottom width, including zero, side slopes, maximum flow height, underdrain, gravel bottom, different layers of materials, and the ability to assign a c value to the swale.
Some of the new fangled requirements for these swales may be called vegetative swales for LID and stormwater approaches, one of which can be foundn in that manual.
