Yes, I agree to this comment that questions need to be more specific.

Coming back to the original question on watershed modelling, there has been
some efforts in identifying a REW (Representative Elementary Watershed) -
which primarily identifies a smaller representative scale of the watershed
scale. One can then do simulations on the REW scale. Here are some
references:
