Using Radioactive Tracers to Determine the Ages of Streamflow

by Ilja van Meerveld 18 March 20197 March 2022

Radioactive isotope tracers can be used to determine the relationship between the ages of water that is stored in soil and bedrock, water in streams, and the water used by vegetation.

Some Waterfalls May Be Self-Made

Kimberly M. S. Cartier, News Writing and Production Intern for Eos.org by Kimberly M. S. Cartier 13 March 201927 April 2022

Waterfalls sometimes imply a past dramatic event, like tectonic uplift or a landslide. Self-formed waterfalls could challenge that interpretation.
