100 km2, Strahler 3 Mesh, Outlet 20, Geology + rivers, 30% buffer

Note

This page and its static assets are auto-generated by python -m tools.doc_gallery. The Sphinx build only reads committed PNG and JSON artifacts.

This family captures repeated conformal meshing runs on the 100 km2 Strahler-3 selection so the gallery can compare several outlets under one stable geology-plus-rivers setup.

Original mesh figure copied from the imported meshing run and reused directly in the documentation.

Regional framing figure copied from the imported meshing run.

Case Setup

• Case family: 100 km2, Strahler 3.

• Gallery repetition: 2/5.

• Scale target: 100 km2.

• Outlet identifier: 20.

• Gallery variant: Geology + rivers, 30% buffer.

• Bundle-reported constraints mode: geology_rivers.

What It Shows

• How several Strahler-3 outlets around 100 km2 compare under the same meshing policy.

• How one filtered 100 km2 selection differs from the headwater-oriented 100 km2 family.

• How repeated imports from batch outputs can stay deterministic across documentation refreshes.

Key Metrics

• Nodes: 1706

• Cells: 3372

• River edges: 488

• Geology interfaces: 334

Reproduce

Run the underlying example or validation case with:

python -m tools.doc_gallery

Refresh the committed gallery artifacts with:
