The Miaoli Tableland (northwestern Taiwan) consists of a sequence of fine-grained tidal to coarse fluvial late Quaternary sediments which underwent a spatially differentiated uplift and fluvial dissection. They reveal repeated rework processes of fluvial cobbles from the highlands to the coast. A new landform classification based on high-resolution 3D terrain analysis results in a new interpretation of the landform evolution. The results favour a local rarely used Quaternary stratigraphic code.
