Glacial trimlines are visible breaks in vegetation or landforms that mark the former extent of glaciers. They are often observed as faint lines running across valley sides and are useful for mapping the three-dimensional shape of former glaciers or for assessing by how much present-day glaciers have thinned and retreated. Here we present the first application of a new trimline classification scheme to a case study location in central western Spitsbergen, Svalbard.

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.

A main element in Büdel's concept is his quite provocative link between climate zones and geomorphological processes, a strong relation which was frequently contested later. Büdel's contribution is still relevant in modern times as the present-day climatic change will probably also invoke a poleward shift of climatic zones, accompanied by associated shifts in geomorphological environments and ecosystems.
