We are pleased to announce the publication of the long-awaited Panta Rhei synthesis volume: Coevolution and Prediction of Coupled Human–Water Systems: A Sociohydrologic Synthesis of Change in Hydrology and Society, has now been formally published by Elsevier and is available online in open access. This book represents the culmination of the Panta Rhei scientific decade (2013–2022), a global effort to understand and predict dynamic interactions between people and water.

Led by editors Fuqiang Tian (Tsinghua University), Jing Wei (Tsinghua University), Melissa Haeffner (Portland State University), and Heidi Kreibich (GFZ Potsdam), the book brings together contributions from 160 authors across natural and social sciences, supported by a distinguished 27-member Editorial Advisory Board. The book provides:

• A holistic sociohydrological framework
• Integrative theories, methods, and data bridging hydrology and social sciences
• Deep dives into major human–water systems: floods, droughts, agriculture, transboundary rivers, and global teleconnections
• Worldwide case studies illustrating emergent phenomena
• A grand synthesis and future vision for science and practice.

For whom:

• Researchers in hydrology and social sciences
• Graduate students entering interdisciplinary water research
• Practitioners and policymakers in water governance
• Members of IAHS working groups.

IAHS expresses warm appreciation to all contributors whose efforts made this synthesis volume possible!
