AGU Catchment Hydrology Technical Committee

@agucatchhydro.bsky.social

We are the Technical Committee on Catchment Hydrology of the American Geophysical Union. www.hydrocatch.weebly.com

At AGU H3S, we want to highlight hydrology ECRs who are hosting sessions at AGU 2026, including this great session on non-perennial streams! If you are a hydrology ECR convening an AGU session, feel free to DM us to promote it. REMINDER: abstracts are due Wednesday, 05 August 2026 at 23:59 EDT!
