> Infiltrated water is retained for an average of 45 d before resurfacing, confirming the system’s ability to contribute to dry-season flows. We estimate that upscaling the system to the source-water areas of the city of Lima can potentially delay 99 × 106 m3 yr−1 of streamflow and increase dry-season flows by 7.5% on average, which may provide a critical complement to conventional engineering solutions for water security.

- gus_massa 5y agoI can't see the paper, but there is some interesting technical details in the supplementary data https://static-content.springer.com/esm/art%3A10.1038%2Fs41893-019-0307-1/MediaObjects/41893_2019_307_MOESM1_ESM.pdf https://static-content.springer.com/esm/art%3A10.1038%2Fs418... In page 15, table 2 they show that they put some Eosin https://en.wikipedia.org/wiki/Eosin https://en.wikipedia.org/wiki/Eosin upstream before the water entered the earth, and then they collected water from the springs downstream a few weeks later and measure how much Eosin was there, and used this to estimate how long the water was stored.
