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.
