Waterar Link

: Using sensors to detect ripples in real water and projecting digital "fish" or "waves" that react to the movement.

Researchers often experiment with using real water as a surface for AR. Projects like these focus on:

Water that exists as water rights claims in legal documents but not in the real world is known as "paper water". California Water Impact Network waterar

If you provide a few more details—like the authors, the specific technology (e.g., "water-resistant paper" or "underwater AR"), or where you heard the name—I can help you track down the exact paper. Over Allocation - California Water Impact Network

There are several papers on using AR to "see" hidden water infrastructure:
