Significance Meandering tidal channel networks play a central role in the ecomorphodynamic evolution of landscapes they cut through. Despite their ubiquitous presence and relevance to sedimentary landscape features, few observations tidal-meander exist, we lack full understanding governing processes. Field analyses show that meanders, traditionally viewed as stable display modes migration rates per unit width quite similar those characterizing fluvial counterparts, with important implications for characterization related products. The results presented here contribute our morphological landscapes.
