12. Network topology

The network topology contains information about the stream network and the routing basins the network is in. These include:

  1. Unique indices of the stream segment;

  2. Unique indices of the routing basins (HRUs; equivalent to SUMMA GRUs in this setup);

  3. ID of the stream segment each individual segment connects to (should be 0 or negative number to indicate that segment is an outlet);

  4. ID of the stream segment a basin drains into;

  5. Basin area;

  6. Segment slope;

  7. Segment length.

Values for these settings are taken from the user’s shapefiles. See: https://mizuroute.readthedocs.io/en/master/Input_data.html
