[Jorge E. San Juan]

Dear colleagues,

We would like to bring to your attention the AGU25 session, "EP023 - Landscape Biophysical Interactions: Hydrodynamics, Sedimentary Processes, and Morphodynamics."

How do plants, animals, and microbes shape rivers, estuaries, and coastlines? This session welcomes research on biogeomorphic interactions—the dynamic interplay between vegetation, fauna, and sediments—and how they influence flow, transport, and ecosystem resilience.

Topics may include responses to climate change, human impacts, extreme events, and restoration or management efforts across diverse freshwater and marine environments. We invite contributions that connect ecological and physical dynamics through fieldwork, lab experiments, modeling, or remote sensing.

Please submit your abstracts by Wednesday, 30 July 2025, 23:59 EDT/03:59 UTC. The AGU Fall Meeting will be held in New Orleans, Louisiana, from December 15 to 19, 2025.

We look forward to seeing you in December!

Cordially,
 
Session Conveners:

Session Description:
Biophysical interactions between hydro-morphodynamic, biological, and ecological processes shape riverine, estuarine, and near-shore coastal landscapes. Organisms within the water column and the substrate can affect flow, sediment transport, and geomorphology at various scales. This session welcomes scientific advances in biogeomorphic interactions across environments. Areas of interest may include sediment-vegetation-faunal interactions and their effects on flow, sediment transport, mixing, and carbon sequestration. Research topics may include biophysical responses to human impacts, extreme events, climate change, and management practices aimed at improving ecosystem resilience. We encourage the participation of studies that include aquatic vegetation, microbial mats, algae, oyster and coral reefs, fish, and micro- and macrofauna. This session covers a wide range of freshwater to near-shore marine settings, including steep and low-relief streams, estuaries, deltas, barrier islands, coastal lagoons, marshes, mangroves, seagrasses, and reefs. We welcome contributions connecting ecological and physical processes using field, laboratory, remote sensing, theoretical, statistical, and numerical methods.
