Arranges a channel network enumeration starting from the identification of the branch according to Hack. The main stream is of order 1 and its tributaries of order 2 and so on, the sub-tributaries are of order 3 and so on.
The model can run in two different modes:
- 0 : standard mode
- 1 : Hack enumeration based on Netnumbering
Inputs
- the file containing the drainage directions (obtained with Markoutlets, DrainDir, FlowDirections)
- the file containing the total contributing areas (obtained
with DrainDir, Tca or Multitca)
- the file containing the Hack lengths (obtained with HackLength)
- the file containing the channel network (obtained with ExtractNetwork)
- only for mode 1: the file containing the channel enumeration (obtained with NetNumbering)
Output
- the file with the net order according the Hack lengths
Notes
The Hack order corresponds (one to one) to the old Horton's network enumeration.
To run the model it is necessary that the outlet pixel presents a drainage direction value equal to 10. If there is not such identification, the program will not work correctly.
