Reach Junction

[Anonymous]

Hi every one! I am doing a flood inundation mapping, i had made a hecras geometry file by using hecgeoras but the problem i am facing is that i couldn’t get the automatic junction nodes created at the reaches junction point, so when i run the steady flow analysis it gives me an error that missing boundary condition on downstream side of profile 1. Needs help on this issue…

Make sure the reach lines snap together in GIS. That way GeoRAS will recogni=
ze the junction. If you don’t want to go back to GIS to do this, you can cre=
ate a junction by moving the reach end points on top of each other. Use the “=
Edit…Move Points/Objects” feature.=20
