Examples of the types of gully erosion as shown in the LUCAS 2022 technical reference document. (a) Ephemeral gully formed in a bare potato field with ridges and furrows (near Neuville en Condroz, Belgium). (b) Permanent gully formed in a grassland valley bottom (near Barlad, Romania). (c) Badlands with multiple gullies forming a dense drainage network developed on Pleistocene clays (near Atri, Italy). All photos were provided by Jean Poesen.
