“…Belnap (2006) suggested that differences in flora and morphology also contribute to these differences, which was confirmed by Chamizo et al (2012). According to the literature, these biocrust have runoff coefficients comparable with bare soil and larger than those from the rest of surface classes (Alexander & Calvo-Cases 1990;Cantón et al 2011;Li et al 2005;Solé-Benet et al 1997). Despite these high runoff coefficients, evidence for the ability of biocrusts to reduce erosion was found long ago, as reported by Booth (1941), who reviewed studies since 1888 and proposed a role for soil algae in controlling erosion.…”

“…The Cyanobacterial crust is primary a coloniser and is progressively replaced by Lichen crusts over time (Lázaro et al 2008) except in the sunniest sites. The study area has a 'Hortonian' (Horton 1933) hydrological response (Solé-Benet et al 1997) see Calvo-Cases et al (2014) for a general description. We selected two areas: C, where Cyanobacterial crust (C) dominates, and L, dominated byLichen crust (L).…”

“…Therefore, water erosion depends on rainfall erosivity (mainly determined by the amount and intensity) (Angulo-Martinez & Begueria 2009;Wei et al 2010), soil erodibility, which is controlled by the soil texture, the amount and stability of the aggregates and the organic matter content (De Baets et al 2006;Solé-Benet et al 1997) and land cover (cover, size and density of the vascular plants, of biocrusts, stones, litter) (Boix-Fayos et al 2007;Zavala et al 2009;Cantón et al 2011). Erosion also depends on topography (including surface roughness, as well as the slope angle and the size of the drainage areas) and antecedent soil moisture (Bowker et al 2008).…”

In drylands, water erosion can be a process with important economic and ecological implications, and is very dependent on the soil surface cover. There is broad agreement that biocrusts protect the soil from erosion in a wide range of circumstances. However, there is little information available on the effect of rain and biocrust types on this protective capacity and there is particularly very little knowledge on the erosive effects of runoff on biocrusts, which are expected to be larger in larger drainage areas, on the resistance of biocrusts to the combined effect of raindrops plus runoff flow and on the solute mobilisation by runoff in biocrusts. To answer these questions, we performed 96 rainfall-simulationin situ factorial experiments, including two biocrust types (cyanobacteria and lichens), three rain types (42, 63 and 77 mm h −1 , always 20 min rain), four plot lengths (1, 2, 3 and 4 m long) and four replicates. In each experiment, runoff volume was measured and a runoff sample was taken to determine (i) the amount of dry matter in runoff, (ii) the amount of organic matter among the dry matter, (iii) the electrical conductivity, pH and alkalinity in runoff water. The main findings were: biocrusts strongly protected soil against water erosion, even under the most erosive conditions, and the protection increased with the successional development. Biocrusts were very resistant to the impact of raindrops and also to runoff flow, although an emergent hypothesis arose: under the most erosive conditions, a threshold of erodibility could be reached at the cyanobacterial biocrust. The lichen crust also protected the soil against the removal of soil soluble substances. The development of a biocrust could change the chemical composition of the solutes in runoff.

“…Solé-Benet et al (1997) used rain simulations on the badland area located in Tabernas (Andalusia, Spain), in order to evaluate runoff, infiltration and sediment production by considering plant cover and type, length and width of cracks and stoniness. The results showed positive correlations between runoff and slope gradients, and negative correlations between the presence of plant cover and runoff and erosion rates, confirming that vegetation cover protects the soils from erosion processes.…”

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.

“…Un claro ejemplo de ello se puede encontrar en el sureste de la Península Ibérica (López-Bermúdez y Romero-Díaz, 1989;Calvo y Harvey, 1996;Solé-Benet et al, 1997). Sin embargo, durante las últimas décadas se ha evidenciado la presencia de cárcavas en una amplio espectro de ambientes y condiciones climá-ticas .…”
