Sahar Jannesarahmadi is a PhD candidate at the Institute for Geo-Hydroinformatics (GHI) at Hamburg University of Technology. Her research focuses on how salt crystallization influences evaporation dynamics from porous surfaces, processes that are important in hydrological and environmental contexts.

Her EGU25 presentation reported on an experimental study investigating the effects of wind flow on evaporation dynamics and salt crystallization patterns in porous media. The results demonstrated how laminar and turbulent airflow conditions lead to distinct crystal growth and distribution, as well as different evaporation rates, highlighting the complex interplay between evaporation and salt formation and providing insights relevant to hydrological and climatological modeling.
