10 km2, Strahler 3 Mesh, Outlet 1, Rivers only, 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 case is reserved for a catchment mesh where geology is removed from the internal constraint set, but the watershed boundary, support extent, and outside de-refinement stay aligned with the standard gallery workflow.


Case Setup#
Scale target: 10 km2.
Outlet identifier: 1.
Gallery variant: Rivers only, 30% buffer.
Bundle-reported constraints mode: rivers_only.
What It Shows#
How the river network alone structures the internal conformal mesh when geology is not enforced.
How the same buffered watershed support can be compared fairly against the geology-plus-rivers variant.
How outside coarsening still protects the basin focus while simplifying the external region.
Key Metrics#
Nodes: 296
Cells: 574
River edges: 90
Geology interfaces: 83
Reproduce#
