I am Getting higher stream number for lower order streams in my analysis on ArcGIS, order 6 has more streams than order 5. is this common in morphometric analysis?
Without a little more information on your project and files, it seems like your GRIDCODE value stands for your
ranking order, and the
count merely stands for the size (number of cells) of your feature.
If that's the case, it means that your stream of rank 6 is bigger than that of 5. I'm not sure if it's logically reasonable without knowing a little more about what you are trying to do. If the order of your stream is solely decided by the size of each, then probably no.
