DOI: 10.1002/esp.5074
Abstract: In gully erosion, the detached soil can be transported over long distances along the landscape. The eroded material can be redistributed and/or deposited on the soil surface along the landscape and then eventually be buried… read more here.

DOI: 10.1016/j.catena.2020.104712
Abstract: Abstract Drylands are exposed to gully erosion expressed by an incised channel surrounded by affected landforms. Although each relevant landform has unique patterns, their connectivity with the gully creates geomorphological interrelations that affect the ecological… read more here.
