Morphometry of widespread tidal meander cutoffs discloses similarity to fluvial morphodynamics

Key Points: • Tidal meander cutoffs are far more common than typically thought and share remarkable morphometric similarities with fluvial counterparts. • Similar mechanisms trigger cutoffs in both tidal and fluvial landscapes, with differences arising only during post-cutoff evolution. • Tidal cutoffs seldom disconnect from parent channels and form oxbow lakes due to the enhanced hydrological connectivity of tidal wetlands.
