In many cases dense vegetation grows on the river banks, in these situations would be very useful to define a different roughness inside the bank stations in the HEC-RAS cross section.
However this is a very boring job, expecially if there are tens or hundreds cross section in the model.
This APP creates a new HEC-RAS geometry defining the roughness (user defined) for vegetated sections.
The vegetated sections are automatically defined by APP between bank stations and a level defined by HEC-RAS simulation.

Also the VBA code in the Excel file is unprotected an you can read it and copy and past if useful
