“…Fluvial erosion plays a major role in the geomorphic formation of steep slopes (Bryan, 2000) in agricultural (Diodato and Bellocchi, 2000;Auerswald et al, 2000) as well as in natural landscapes of the Alps (Wetzel, 1992;Haas, 2008) or the Mediterranean region (Clarke and Rendell, 2006;Mathys et al, 2005). Especially in the Mediterranean regions, the climatic conditions in combination with the topography and the lithology lead to intensive gullying and bad land generation (Della Seta et al, 2009;Aucelli et al, 2012), with high intensities on steep and barely vegetated slopes (Haas et al, 2011).…”

“…The investigation of geomorphic processes, e.g., fluvial erosion on hilly or mountainous slopes in Mediterranean regions, was often done by using analog methods like erosion pins or sediment traps (Della Seta et al, 2009;Haas et al, 2011;Clarke and Rendell, 2006); but they are often hard to use and error-prone, as their use can lead to other influences on the investigated slopes (Haas et al, 2011). Moreover, the spatial and temporal resolution of these methods is normally very limited with consequences for the interpretation of the results (Haas et al, 2011).…”

Abstract. This study focuses on the quantification and analysis of geomorphic processes on the barely vegetated slopes of a recultivated iron ore mine on the Italian island of Elba using photographs from terrestrial laser scanning (TLS) and digital photogrammetry by an unmanned aerial vehicle (UAV) over a period of 5 1/2 years. Beside this, the study tried to work out the potential and the limitations of both methods to detect surface changes by geomorphic process dynamics within a natural environment. Both UAV and TLS show the pattern of the erosion and accumulation processes on the investigated slope quite well, but the calculated amounts differ clearly between the methods. The reasons for these differences could be found in the different accuracies (variable level of detections) of the methods and the different viewing geometries. Both effects have an impact on the detectable process dynamics over different timescales on the slope and their calculated amounts, which in both cases can lead to an underestimation of erosion and accumulation by fluvial processes.

“…Badlands are common in semi-arid regions with strongly marked seasonal contrast climates, while seem to be rare in regions with constant-uniform rainfall. Several geomorphic processes are involved in their origin, namely: weathering, rill and interrill erosion, gullying, piping, tunnel erosion and mass movements (Bazzoffi et al, 1997;Clarke and Rendell, 2006;Farifteh and Soeters, 2006;Della Seta et al, 2009;Faulkner, 2013;Vergari et al, 2013). The primary factor influencing badland formation is the action of water: little miniature gullies form and enlarge as time passes, thereby causing destruction of the slope.…”

“…In Italy, badlands are mainly distinguished in two types: biancane and calanchi. The former are mainly interpreted as residual hills of late stage calanchi evolution (e.g., Farifteh and Soeters, 2006), where slope retreat of calanchi fronts (Clarke and Rendell, 2006) or joint systems (Della Seta et al, 2009) may have played a prominent role; they are characterised by cones and hummocks separated by flatter surface wash deposits, and creep or similar processes (e.g., solifluction) may affect their upper crust (Pulice et al, 2012). The latter, on the other hand, are characterised by a heavily dissected terrain with steep, unvegetated slopes and channels with a dendritic pattern, which rapidly incise and extend headwards (Alexander, 1982;Moretti and Rodolfi, 2000;Farifteh and Soeters, 2006;Buccolini et al, 2012;Pulice et al, 2012).…”

Calanchi are erosion landforms characterised by a heavily dissected terrain with steep, unvegetated slopes and channels with a dendritic pattern, which rapidly incise and extend headwards. Recent literature focusing on badland systems highlights their similarity with other larger fluvial landforms, stating that these behave as a full size laboratory, due to their rapid development in space and time and to the diversity of geomorphic processes involved.In this paper, a brief review of the most important results on badland research is firstly presented. Then, the morphometric similarity between calanchi and other erosion landforms is discussed. Finally, models quantitatively relating the volume of sediments eroded from calanchi landforms and a set of geometric features of their tributary areas, by exploiting the dimensional analysis and the self-similarity theory, are presented.

In particular, Basilicata region (southern Italy) is very susceptible to both gravitational phenomena and water erosion processes (Bentivenga, Palladino, & Caputi, 2012;Caniani, Pascale, Sdao, & Sole, 2008;Capolongo, Pennetta, Piccarreta, Fallacara, & Boenzi, 2008;Clarke & Rendell, 2006a;De Bari, Lapenna, Perrone, Puglisi, & Sdao, 2011;Pascale, Sdao, & Sole, 2010;Piccarreta, Capolongo, & Boenzi, 2004;Polemio & Sdao, 1998), due to the peculiar combination of its geological, morphological, climatic settings, together with its unsustainable land management, e.g. increasing urbanization, intense agricultural and deforestation (Gullà & Sdao, 2001).…”

This paper performs denudation processes and landforms characterizing the Camastra River catchment (Basilicata -South Italy), on a 1:40,000 scale map. The map, which includes gravitational processes and landforms and water erosion processes and landforms, was obtained by combining field surveys with the analysis of topographic maps and of multitemporal aerial photos, ranging from 1954 to 2010. These latter provided information on both spatial and temporal evolution of geomorphic processes. The integration and the elaboration of the data obtained in a GIS environment provided the inventory map of denudation processes and landforms. Landslides are widespread in the study area, and play an important role in the present-day landscape evolution. A total of 953 landslides were recognized, occupying a surface of 79 km 2 , about 22% of the whole study area. The recognized landslides were mapped on the basis of movement type, as follows: slides, flows, falls and complex landslides. With regard to water erosion processes, the most evident and spectacular landforms in the study area are represented by badlands (the so called calanchi), due to concentration of running water on steep clayey slopes, producing narrow and knife-edge ridges. Finally, sheet, rill and gully erosion are particularly active on areas devoid of vegetation cover, as well as on cultivated fields. This kind of map is an useful tool for land planning policy. Also, these types of studies are basic and complementary to applied methods for investigation and mapping of land susceptibility to denudation processes, as landslides and water erosion.
