Hey,
i have created a Project with a .CSV file. I now wondering if its possible to edit the Down Stream Reach Length automatically or is there a Tool which can measure the distances?
Many thanks
Johnny
Reach lengths can be editted manually within HEC-RAS, both in the cross section editor and in the Reach Length table in the geometry schematic “Tables” menu item.
To automate the process of determining reach lengths, you have to use flow lines in HEC-GeoRAS.
A way that isn’t exactly the most accurate to make the software update the lengths is to create a new dummy cross section. Just the section will do no need to populate it. Then delete it. RAS should prompt you and ask if you want it to automatically adjust lengths.
