International Workshop on Ecohydrogeology

Monday, July 20, 2026 - Tuesday, July 21, 2026 (all day)

International Workshop on Ecohydrogeology

The International Workshop on Ecohydrogeology will bring together researchers, practitioners, and students from around the world to explore connections between water, ecological, and geological systems.

July 20 will feature research seminars showcasing cutting-edge studies from around the world, highlighting the diversity of research in ecohydrogeology.

The second day, July 21, will feature a Water Talk by Professor Yanxin Wang from the China University of Geosciences, followed by meetings and discussions that will provide attendees with the opportunity to connect, exchange ideas, and build relationships.

The International Workshop on Ecohydrogeology will strengthen collaboration, support ongoing academic exchange, and encourage joint research and knowledge mobilization initiatives. By connecting researchers across regions and disciplines, it will help build lasting partnerships and support more integrated approaches to solving complex environmental challenges.
