“…The morphology of the gully system is focused on the influencing factors of size and length (Kompani-Zare et al 2011), and ignores the importance of influencing factors of the distributive direction. This paper focuses on the distributive direction of gully system; 270°is the Bdominant^direc-tion of gully system in the Yuanmou Dry-hot Valley.…”

Gully systems develop widely in the Yuanmou Dry-hot Valley. Based on the Scheidegger method and the non-parametric method, this study interpreted 1599 gullies using a DEM with a scale of 1:50,000, and remote sensing images were photographed by QuickBird. The objectives are to explore the regularity that is shown in the distributive direction of the gully system and to understand the factors (including aspect, slope, and the neotectonic stress field) that control the distributive direction of the gully system. The results show that (1) the maximum Bdominant^direction of the overall, the third and fourth order, the east, above 1400 m gully are 270°; the Bdominant^direction 270°has relative superiority. So 270°is the Bdominant^direction of the gully system in the Yuanmou Dry-hot Valleys area. (2) The slope of 38°is the threshold value which separates the overall slope range. When the slope is in the range 0-38°, the slope is the dominant factor; when the slope is in the range 38-59°, aspect is the dominant factor. So, with the increase of slope, 38°is the threshold value, and the dominant topographic influence is changed from slope to aspect. (3) The direction of the compressive stress field, 157.5°, is proven not to conflict with the directions 146.3, 157.5, 169, and 180°that are the principal compressive stresses calculated for the gully system. So the collision and extrusion of plates can form fracture surfaces which provide a favorable condition for the development of drainage and gullies. The distributive direction of the gully system is comprehensively affected by the neotectonic stress field, the terrain, and other factors. Therefore, the study of the distributive direction of the gully system not only enriches the content of morphology on the landform but can also be the basis for the evolutional direction of the gully system that is effectively predicted in the study area, and it provides scientific guidance for industrial and agricultural production layout and the construction of infrastructure.

“…Similar empirical volume-length relationships were also successfully tested on rills, ephemeral gullies (EGs), permanent gullies (gullies) and badlands, developed in different environments (Nachtergaele et al, 2001a;Capra et al, 2009;Di Stefano and Ferro, 2011;Kompani-Zare et al, 2011;Caraballo-Arias et al, 2014).…”

“…Gully erosion studies have used simple empirical equations for analyzing the morphometric and hydraulic characteristics of gullies (Nachtergaele et al, 2001a(Nachtergaele et al, , 2001b(Nachtergaele et al, , 2002Capra et al, 2005Capra et al, , 2009Bruno et al, 2008;Di Stefano and Ferro, 2011;Kompani-Zare et al, 2011;El Maaoui et al, 2012;Di Stefano et al, 2013;Frankl et al, 2013;Caraballo-Arias et al, 2014). Since gully erosion processes are often considered similar to those occurring in other types of channelized water flows, many of the empirical equations used for gully erosion assessment have their origins in rills, streams or rivers.…”

“…Taking into account that Nachtergaele et al (2001), Capra et al (2009), Di Stefano andFerro (2011) and Kompani-Zare et al (2011), demonstrated that length of rills, ephemeral gullies (EGs) and permanent gullies (gullies) can be used to obtain a reliable prediction of eroded volumes by applying the following power relationship: (4) where a and b are coefficients, V (m³) is the total eroded volume and L (m) is the total channel length, the applicability of Eq. (4) was tested by Caraballo-Arias et al (2014) for the 25 badland channels.…”

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.
