confluence

Given a vector stream network, compute topology and derived attributes: Strahler order, mainstem, network and path IDs, upstream/downstream queries, and cross sections.

from confluence import analyze_network

annotated = analyze_network(vector_network)

_{Only the largest connected network (by network_id) is shown.}

from confluence import create_cross_sections

cross_sections = create_cross_sections(
    annotated.geometry, interval_distance=200, width=500
)
