Hello
Which option should I choose in the analysis section of flow 3d software to get the depth of the scour hole, of course there are similar options, but they do not give the desired output (I put the similar options in the attachment)!!

Hi. Usually 'Packed Sediment Elevation Net Change' should do the job. Just add/subtract the value obtained from Flow 3D simulation, from NSL which you have used as input geometry.

Hello, thanks, I did what you said and sent the result in the attachment, unfortunately I didn't get the desired result, what do you think is my mistake? And about the subject you said (Just add/subtract the value obtained from Flow 3D simulation, from NSL which you have used as input geometry.) How should I do this?

You can view it in 2D mode as shown 'start' and 'end' simulation picture in attached file. Alternatively you can use 'Text Output' option to extract data in excel file, to check scour depth numbers while adding/subtracting it from initial NSL profile.
