Morphology parameters of ephemeral gully in characteristics hillslopes on the Loess Plateau of China

Spatial heterogeneity of soil detachment capacity by overland flow at a hillslope with ephemeral gullies on the Loess Plateau

“…Furthermore, ephemeral gullies can accelerate interrill and rill erosions via increasing the local slope gradient after several void-filling cycles Poesen et al, 2003). On the Chinese Loess Plateau, especially on steep slopes, ephemeral gullies approximately contribute to 35-70% of the slope soil loss (Cheng et al, 2007;Gong et al, 2011). A better understanding of ephemeral gully erosion processes and their potential effect is of paramount importance to identify the innate characteristics of soil erosion on the Loess Plateau.…”

WITHDRAWN: Estimation of the sediment transport capacity in eroding ephemeral gullies with a flume experiment method

“…In the last decades, the importance of gully erosion has been widely recognized (Capra et al, 2009;Cheng et al, 2007;Daggupati et al, 2014;Nachtergaele et al, 2001;Stefano et al, 2013;Woodward, 1999). Poesen et al (2003) distinguished ephemeral gullies from rills by a critical cross-sectional area of 929 cm 2 (1 ft 2 ), while others defined it with a critical width, such as 0.3 m (Brice, 1966) or 0.5 m (Imeson and Kwaad, 1980).…”

Modeling the evolution of loess-covered landforms in the Loess Plateau of China using a DEM of underground bedrock surface

“…Since the 1950s, much attention has been paid to loess landforms from geological and geomorphological viewpoints. Some scholars investigated the regional variation of soil erosion and the stages of geomorphological developmental of landforms in the Loess Plateau (Stolte et al, 2003;Xu et al, 2004;Cheng et al, 2007;Chen et al, 2008;Zheng et al, 2008;Chen et al, 2010;Hughes et al, 2010;Liu and Liu, 2010;Fu et al, 2011;Zhu, 2012;Xiong et al, 2013). Liu (1985) investigated profiles of loess deposits for the three typical landforms in the Loess Plateau (hill, ridge, and tableland), and found that the sedimentary environment of loess deposits, including the underlying bedrock paleotopography, has been related to climate change.…”
