How to obtain the topography of the sedimentary bed?
 

Hi, my thesis is numerical, so I need to validate it, so I chose a lab article, which was about scour around spur dike. Now I want to make a comparison between the output image of the laboratory article, which is related to the topography of the bed after scouring, with the output results of the flow 3d software, but I don't know which part of the analysis part of the software to get the appropriate output, the relevant photo is in the attachment I sent ?!
