ECHN Japan

The Japanese Chapter of the Early Career Hydrogeologists’ Network


What is the IAH-ECHN?

The Early Career Hydrogeologists’ Network (ECHN) is an official network of the International Association of Hydrogeologists (IAH).  The ECHN is connecting hydrogeologists at the start of their careers. The ECHN organizes events, contributes to IAH conferences, and provides a forum all focused on the needs and interests of early career hydrogeologists. Find more information about the general work of ECHN and how to participate here.


About the ECHN-Japan

The ECHN-Japan is the Japanese national branch of the IAH-ECHN. We aim to bring together Japanese hydrogeologists who are on the way to, or at the beginning of their professional careers. We want to build a local and vibrant community of friends and colleagues that share the same passion for water in all its different scientific, engineering, and socio-economic aspects.
