Can 1d cross section cut lines and 2d area boundary intersect?

[ptdcaliguid]

Hello, I’m developing a 1d-2d model and would like to ask if 1d cross section cut lines and 2d area boundaries can intersect?
Thank you

Yes, though be sure not to overlap too much or you will potentially double count volume (if the xsec station-elevation data is generated from the terrain). Also think about how you will lay our your lateral structures. In a perfect world the xsecs and lateral structures would snap to the 2D boundary edge. But some minimal overlap or gaps are generally ok.

That is useful to know @ldguethle

I have surveyed 1D cross sections (sample below) I want to connect to 2D flow areas. My intention is to draw the lateral structure (and 2D flow area) just outside the bank stations; thus would leave 10-15m of the XS overlapping with the 2D flow area. As there are >100 XS, this will be time consuming to crop each one – so I am wondering what effect this may have on the model in order to justify the extra model time? I would appreciate your thoughts.
