[OC] Das Vokabular des Wassers: Zuordnung kurzlebiger und dauerhafter Bachnamen in den USA (GNIS-Daten)

* **Data Source:**[USGS – The Language of Water](https://waterdata.usgs.gov/blog/vizlab-stream-names-map/).

**Methodology & Context:** The goal of this map is to visualize how regional terminology reflects local hydrology. By filtering specific keywords in stream names, we can see a „linguistic fingerprint“ of the American landscape:

* **Ephemeral/Arid Names (Warm Glow):** Terms like *Arroyo, Wash, Gulch,* and *Draw*—indicative of seasonal or flash-flood water features common in the West and Southwest.
* **Persistent/Lowland Names (Cool Glow):** Terms like *Bayou, Swamp, Marsh,* and *Slough*—indicative of slow-moving, year-round water features common in the Southeast and Mississippi Delta.

The density of these points highlights the transition from the humid East to the arid West, roughly following the 100th meridian.
