Flooplain mapping with HEC-RAS v. 4.1 results

[Anonymous]

Hello everyone.
I received a model made with HEC-RAS v. 4.1. I need to extract depth and velocities from that model without running again the model.
How can I do that? Is there a way to import results into HEC-RAS v. 5.0.7 and extract what I need from Ras Mapper?

Thanks

Version 4.1 does have a Mapper, it is just a little more basic. You could just export the data for GeoHEC-RAS as well and create some layers in GIS.

Hello Cameron, thanks for your reply.
Sorry if my question seems easy but I am a new user of Hec-Ras and I always used it from v. 5.
I need to export grid of Depth and Velocities. Am I able to do that from Hec-Ras 4.1 Mapper?
Could you tell me how to do that or link something that shows the procedure?

Chapter 20 of the user’s manual discusses how to get velocity and wse from Mapper which can then be used to get depth.

The other option would be HEC-GeoRAS
