Imported and interpolated sections differing velocity results

[Fraser]

Hi there,

I am working on a model where we have limits on the permissible velocity in the channel. I have made several changes to my geometry and recently needed to import a previous version which I had saved (by starting a new geometry and importing HEC-RAS format data).

I have noticed that when I interpolate sections in this reach and run the model, the velocities in my interpolated sections are very different to the velocities in my imported sections (see image).

Does anyone know why this might be happening?

Thanks,

Fraser

Are the bank stations and roughness values correct? When you interpolate, roughness values get interpolated also.
