Total number of values in this section = 7 R.


OUTPUT:

Watershed or basin:  
Number of upland watersheds:  
Number of reach watersheds:  

(1)(2)(3)(4)(5)(6)(7)
Reach
watershed
Topological
No.
Upstream
reach watershed
Side reach watershed or
upland watershed
Upland watershedUpstream reach watershed topological No.Side reach watershed topological No.

Note:  For a given reach watershed in Col. 1, a zero in Column 3 indicates a contribution only from the upland watershed in Col. 5. Conversely, a nonzero in Col. 3 indicates contributions from the two (upstream and side) reach watersheds in Cols. 6 and 7.
