Features

• Splitcatchment function delineates drainage basins from an input pour point.
• Flowtrace function traces the flowpath of water from an input point to the nearest stream.

Usage

In a python project, first import nldi-flowtools. Then either the Splitcatchment or Flowtrace function can be used.

from nldi_flowtools import nldi_flowtools

nldi_flowtools.splitcatchment(-93, 45, True)
nldi_flowtools.flowtrace(-93, 45, 'down')
