Die zweisprachige internationale wissenschaftliche Fachzeitschrift „Mitteilungen der Österreichischen Geographischen Gesellschaft“ („Annals of the Austrian Geographical Society“) ist das wichtigste regelmäßig erscheinende Organ der „Österreichischen Geographischen Gesellschaft“. Sie erscheint seit 1857 und ist die älteste noch existierende Fachzeitschrift geographischen Inhalts im deutschen Sprachraum. Dabei werden neue Erkenntnisse aus allen Bereichen der Geographie, Kartographie und verwandter Raumwissenschaften vermittelt, über Fachfragen in Forschung und Lehre, nationale und internationale geographische Aktivitäten sowie über Personalia informiert und Gesellschaftsnachrichten publiziert.

Gully erosion is a special form of water-induced soil erosion and is often accompanied by devastating geomorphological effects on the landscape. It is characterised not only by high rates of soil loss, but also by lasting changes in the landscape as well as its degra-dation.Extensive research on gully erosion has increased in the last two decades. Although studies on this topic had been conducted previously too, they were rather scarce. In Austria, only few studies have dealt with this specific form of soil erosion to date. Accordingly, one of the main objectives of this study was to issue an inventory of gully erosion in a selected study area in Lower Austria. To this end, identified erosion sites were mapped and displayed on a hotspot map to provide an overview of where accumulations of gullying can be found. In addition, a geomorphometric analysis was carried out to provide infor-mation about soil and sediment loss induced by gully erosion, as well as other specific characteristics of selected erosion phenomena. As the results reveal, 2,065 permanent gullies and 289 sunken lanes could be detected in the study area, concentrated in regions characterised by thick loess layers and intensive land use. Moreover, it has been shown that the gullies contribute to considerable soil loss rates. In three representative catchment areas, detailed examinations of the geomorphometric characteristics showed that gully erosion is responsible for more than 1,000,000 m³ of sediment loss. Not only does this lead to the emergence of ‘scars’ in the affected landscapes, but it also leaves agricultural land unusable. Since heavy rainfall events are expected to become more frequent in Austria due to the advance of climate change, soil erosion may likewise increase in the future. Therefore, there is an urgent need to intensify research on soil erosion in order to take corresponding measures and protect the soil from devastating erosion events.
