Length for station - River ID field in river feature OID 2 is not populated

Question

Hello,

I am working with ArcMap 10.2 and Hec GEO-RAS and I have the following error messages when I click on RAS Geometry -> Stream centerline Attribute and then Lengths/Stations :

"River ID field in river feature OID 2 is not populated."

When I try to click RAS Geometry -> Stream centerline Attribute -> All I have the following warning :

"Error occurred in Stream Length Tool"

I have a pretty long river (subdivided in several reaches with the same name, for convenience of the use of the "saving edit" while I was drawing the river) so it would be nice if anyone could help me solving this issue.

Many thanks.

Hello Ladies and Gentlemen!

May be the river did not assigned or the stations not assigned

You Please refer to the User manual "https://www.hec.usace.army.mil/software/hec-georas/documentation/HEC-GeoRAS42_UsersManual.pdf" on the HEC-GeoR tools on the Table 3-1. Summary of HEC-GeoRAS tools. you will see how to assign. Thank you!
