About the meeting
Over the past 15 years since its initial development, the global river model CaMa-Flood has
undergone significant advancements. We have introduced numerous new model schemes,
incorporated new baseline topography datasets, and refined our analysis methods. Furthermore,
CaMa-Flood has become widely utilized for various applications, including flood risk assessment,
Earth’s climate system modeling, and data assimilation.
We are excited to announce the first-ever international meeting for CaMa-Flood developers andusers. This gathering aims to facilitate the exchange of knowledge and expertise, allowing
participants to share insights, discuss current advancements, and explore future developments
and applications of CaMa-Flood.
All CaMa-Flood developers and users are cordially invited to participate in the meeting. Moreover,
we extend a warm welcome to all researchers interested in global river hydrodynamics,
regardless of whether they are currently using CaMa-Flood. We look forward to fostering a diverse
and enriching exchange of ideas and collaborations during the event.
