I have no idea of what the images look like, but I guess that you will have
some lines that delineate the dunes?
If so, you could isolate the area that the lines define and use some kind of
distance transform between these. You will need to calibrate the images and
make sure that the 2 images are aligned (registered) on some other fixed
landmarks.

Good luck with your project, I wished there were projects like these when I
was in high school.
