Floodway Mapping at Junctions

jwp23
I was wondering if there was a way to map floodways through junctions in RASMapper? The floodplains map all the way through junctions to the next reach but it appears (probably because of the defined encroachments) that the floodways stop near the last cross-section / interpolation surface. Is there any solution in RAS? It is easy cleanup when exported to GIS but I was wondering if there was a trick.

No trick besides drawing it in GIS yourself. However, if you replace the junction with a 2D flow area the mapping will continue. But, you would need to convert it to an unsteady state model....
