“…Previous research on ephemeral gully erosion mainly focused on techniques for monitoring and modeling gully erosion Casalí et al, 2006;Dong et al, 2015), gully retreat rates (Vandekerckhove et al, 2003;Hu et al, 2007), topographic thresholds for gully erosion (Vandaele et al, 1996;Nachtergaele et al, 2001;Poesen et al, 2003;Maugnard et al, 2014), and contribution of gullies to soil loss and sediment yield (Auzet et al, 1993;Vandaele and Poesen, 1995;Li et al, 2003;Taguas et al, 2012). For example, Govers and Poesen (1988) discriminated the contributions of inter rill and rill erosion to total soil loss.…”

“…In the Cheney Lake Watershed, both streamflow and sediment were calibrated and validated with the measured data at the outlet, and then the most beneficial conservation practice within the watershed was identified Bingner et al, 2010;. A simulation study of ephemeral gully development under various soil conservation measures suggests grass cover without construction of structures as the most profitable alternative for ephemeral gully control (Taguas et al, 2012). Based on measured soil properties, farming management, and climate input data, simulated erosion rates for gullies that were filled annually by tillage were 250% to 450% greater over a 10-year period than those occurring when gullies were left unfilled by tillage (Gordon et al, 2008).…”

“…Examples are REGEM and its adaptation TIEGEM, both used in the Annualized AGricultural Non-Point Source model (AnnAGNPS; Gordon et al, 2007;Taguas et al, 2012), CHILD (Flores-Cervantes et al, 2006;Campo-Bescós et al, 2013), or the headcut growth model by Rengers and Tucker (2014). Kirkby and Bracken (2009) presented an areal gully growth model that showed how the ratio of channel versus sidewall processes is a key determinant in its evolution.…”

Abstract. Gully erosion is an important erosive process in Mediterranean basins. However, the long-term dynamics of gully networks and the variations in sediment production in gullies are not well known. Available studies are often conducted only over a few years, while many gully networks form, grow, and change in response to environmental and land use or management changes over a long period. In order to clarify the effect of these changes, it is important to analyse the evolution of the gully network with a high temporal resolution. This study aims at analysing gully morphodynamics over a long timescale in a large Mediterranean area in order to quantify gully erosion processes and their contribution to overall sediment dynamics.A gully network of 20 km 2 located in southwestern Spain has been analysed using a sequence of 10 aerial photographs in the period 1956-2013. The extension of the gully network both increased and decreased in the study period. Gully drainage density varied between 1.93 km km −2 in 1956, a minimum of 1.37 km km −2 in 1980, and a maximum of 5.40 km km −2 in 2013. The main controlling factor of gully activity appeared to be rainfall. Land use changes were found to have only a secondary effect. A new Monte Carlo-based approach was proposed to reconstruct gully erosion rates from orthophotos. Gully erosion rates were found to be relatively stable between 1956 and 2009, with a mean value of 11.2 t ha −1 yr −1 . In the period 2009-2011, characterized by severe winter rainfalls, this value increased significantly to 591 t ha −1 yr −1 . These results show that gully erosion rates are highly variable and that a simple interpolation between the starting and ending dates greatly underestimates gully contribution during certain years, such as, for example, between 2009 and 2011. This illustrates the importance of the methodology applied using a high temporal resolution of orthophotos.
