All Estuaries and Deltas (World)

This group collects the 19 Bodies of Water subcategory members that the atlas already places under its own Estuaries and Deltas subcategory, the whole real-world population the atlas covers there. It is a single flat group, not split further by region or country, because Estuaries and Deltas stays well under the atlas's own hundred-member threshold for a further split. It sits directly under the Estuaries and Deltas subcategory and under the atlas's own Groups category, giving a reader a direct browse path from either the Estuaries and Deltas subcategory page or the Groups index.
