Hi to all,

I have question related to delineate the cross-section in HEC-GeoRAS.

In theory, the XS should be straight. However, in some applications, the XS line can be curve as well (like the poster from RiverCAD).

Can anyone explain me where (both along the channel and along a XS) the XS should be straight and where it can be curve?

Best regards,

Tri Van
