Meander‐Bend Erosion Dynamics Along a Gravel‐Bed River: Insights From Short‐Term UAV Monitoring
ABSTRACT Riverbank erosion is a natural process in meandering rivers that contributes to sediment supply and geomorphic diversity, yet it can threaten infrastructure and human activities within the floodplain. Recently, many studies have used high‐resolution remote sensing technologies to measure bank erosion, but they often focus on technical aspects ...

Abstract Pantodonts are an extinct group of herbivorous eutherian mammals. They comprise 8 families and 23 genera, ranging from the early Paleocene to the late Eocene, including Bemalambda, Barylambda, Titanoides, or Pantolambda. In Europe, only one genus is known, Coryphodon, represented by three species: C. eocaenus, C. anthracoideus and C.

Abstract Young scoria cones fed by dike channels or conduits may undergo rapid and substantial post‐eruptive morphological modification; however, the structural controls and mechanisms governing topographic degradation remain poorly constrained. This knowledge gap limits our ability to reliably interpret topography, faults, deposits and the evolution ...
