Waterfall and Cataract Landforms (World)

This group collects the 6 Landforms subcategory members that the atlas already places under its own Waterfalls and Cataracts subcategory, the whole real-world population the atlas covers there. It is a single flat group, not split further by region or country, because Waterfalls and Cataracts stays well under the atlas's own hundred-member threshold for a further split. It sits directly under the Waterfalls and Cataracts subcategory and under the atlas's own Groups category, giving a reader a direct browse path from either the Waterfalls and Cataracts subcategory page or the Groups index.
