Short summary
Short summary
Understanding and predicting the evolution of river landscapes is critical for effective river management. Traditional physics-based morphodynamic models, while accurate, are computationally intensive and often impractical for long-term applications. This study presents a robust deep learning framework, which was designed to overcome the computational limitations by enabling rapid and reliable predictions of hydrodynamic and sediment transport behaviors.

Speleothems are a popular, multi-proxy climate archive that provide regional to global insights into past hydroclimate trends with precise chronologies. We present an update to the SISAL (Speleothem Isotopes
Synthesis and AnaLysis) database, SISALv3, which, for the first time, contains speleothem trace element records, in addition to an update to the stable isotope records available in previous versions of the database, cumulatively providing data from 365 globally distributed sites.

Short summary
Plant molecules, also called biomarkers, are a tool used for reconstructing climates in the past. In this study, we collected soils and stream sediments in a river catchment in Armenia in order to determine how these molecules move before deposition. We found that trees and grasses produce distinct biomarkers, but these are not incorporated equally into stream sediments. Instead, biomarkers from deciduous trees overprint any upstream transport of grass biomarkers.
