“[1888 graduate student Frederick Haynes] Newell is purported to be the person responsible for the adoption of the USGS spelling of “gage” instead of “gauge”. Around 1892, Newell reasoned that “gage” was the proper Saxon spelling before the Norman influence added a 'u'…”

“When it comes to water, the world is changing faster than ever. 🌏 Now you can map it just as quickly within QGIS. Seen [in the first figure] are examples from France and the Dominican Republic, which leverage 11 years of the Landsat-Sentinel Harmonized 30-meter product, to reveal temporal river dynamics, ephemeral rivers beneath a bay, and lake terraces…”

Conceptualizing River Floodplains
--
https://doi.org/10.1029/2024EF005681 <-- shared paper/commentary
--
"PLAIN LANGUAGE SUMMARY: River floodplains are integrative ecosystems in which diverse processes operate together to maintain river health. Floodplains are as critical to river health as the channel itself, yet floodplains lack the legal protections afforded to river channels in many countries.
KEY POINTS
• A river floodplain is an integrative physical, chemical, biological system and a key component of a river corridor
• Contemporary societal perceptions and regulatory frameworks do not reflect this scientific consensus...”
