HEC-RAS Modeling of nonstandard culvert

[Egypt1]

We are a precast concrete producer who has developed a new 3-sided culvert structure (Stronghold Bridge Systems) to compete with Con/Span. Unfortunately for us, Con/Span is listed by name in the pull-down menu for culvert geometry in HEC-RAS 4.0. In order to compete effectively, we will need to determine how to appropriately model our geometry for hydraulics in HEC-RAS.

We are producing an engineering manual for distribution and would like to include strucure geometry and a procedure for hydraulic modeling, but I can't find any information on data format or even what specific data will be required. I've been told that the HEC-RAS data files can be edited since they're just text files, but can't find any specifics. All of the manuals provide information on importing data, but it's all specific to wateway geometry.

Personally, I have no experience with HEC-RAS (I'm a structural engineer), so I don't know if I'm making a big deal out of this or not. If you're interested in what the new sections look like, check out the link below.

Thanks in advance for any help you can provide.
