“…The mechanisms by which changes in a landscape (e.g., due to farmland abandonment) affect the transfer of water and sediment through a drainage basin are a "hot topic" of hydrological and geomorphological research and have led to the increased use of the concept of hydrological connectivity. Recent studies (López-Vicente et al, 2013aQuiñonero-Rubio et al, 2013;Buendía et al, 2016) have shown that farmland abandonment usually decreases hydrological connectivity, mostly because of an increase in vegetation cover.…”

“…Calculation of the IC requires knowledge of the characteristics of the drainage area and of the flow path. This approach is currently the most widely used around the world, including in Turkey (D'Haen et al, 2013), Japan (Chartin et al, 2017), Australia (Vigiak et al, 2012), Italy (Cavalli et al, 2016), Spain (López-Vicente et al, 2013aProsdocimi et al, 2017) and Mexico (Ortíz-Rodríguez et al, 2017).…”

“…However, abandonment of these terraces can generate concentrated runoff and sediment flows along preferential pathways created by the successive collapse of several terraces, promoting connections between these pathways and the main stream network (Calsamiglia et al, 2017). Changes in connectivity can explain changes in catchment runoff response and sediment yield (Meerkerk et al, 2009;López-Vicente et al, 2013a;Dung et al, 2015). Thus, a general decrease in connectivity is expected to reduce streamflow and sediment discharge.…”

ABSTRACT. Vegetation expansion following farmland abandonment is a complex process that depends on multiple natural and human-induced factors, resulting in differences in the evolution of land cover on former cultivated fields, with various environmental implications. To assess the complexity of the hydrogeomorphological consequences of farmland abandonment, the Instituto Pirenaico de Ecología (CSIC) and the University of La P A P E R A C C E P T E D .

“…The concept of connectivity has increasingly been used in quantitative process-based sediment dynamics research, especially at catchment scales (Ali et al, 2014;Baartman et al, 2013;Bracken and Croke, 2007;Bracken et al, 2015;Brierley et al, 2006;Cavalli et al, 2013;Fryirs et al, 2007;Heckmann and Schwanghart, 2013;Lexartza-Artza and Wainwright, 2011;López-Vicente et al, 2013;Wainwright et al, 2011). Geomorphology has been considered as a major driver on determining sediment connectivity (Heckmann and Schwanghart, 2013;Theler et al, 2010), and geomorphometric indices have increasingly been developed to assess it (Borselli et al, 2008;Cavalli et al, 2013;López-Vicente et al, 2013;Reid et al, 2007;Sougnez et al, 2011).…”

Soil water erosion is a serious problem, especially in agricultural lands. Among these, vineyards deserve attention, because they constitute for the Mediterranean areas a type of land use affected by high soil losses. A significant problem related to the study of soil water erosion in these areas consists in the lack of a standardized procedure of collecting data and reporting results, mainly due to a variability among the measurement methods applied. Given this issue and the seriousness of soil water erosion in Mediterranean vineyards, this works aims to quantify the soil losses caused by simulated rainstorms, and compare them with each other depending on two different methodologies: (i) rainfall simulation and (ii) surface elevation change-based, relying on high-resolution Digital Elevation Models (DEMs) derived from a photogrammetric technique (Structure-from-Motion or SfM). The experiments were carried out in a typical Mediterranean vineyard, located in eastern Spain, at very fine scales. SfM data were obtained from one reflex camera and a smartphone built-in camera. An index of sediment connectivity was also applied to evaluate the potential effect of connectivity within the plots. DEMs derived from the smartphone and the reflex camera were comparable with each other in terms of accuracy and capability of estimating soil loss. Furthermore, soil loss estimated with the surface elevation change-based method resulted to be Contents lists available at ScienceDirectScience of the Total Environment j o u r n a l h o m e p a g e : w w w . e l s e v i e r . c o m / l o c a t e / s c i t o t e n v of the same order of magnitude of that one obtained with rainfall simulation, as long as the sediment connectivity within the plot was considered. High-resolution topography derived from SfM revealed to be essential in the sediment connectivity analysis and, therefore, in the estimation of eroded materials, when comparing them to those derived from the rainfall simulation methodology. The fact that smartphones built-in cameras could produce as much satisfying results as those derived from reflex cameras is a high value added for using SfM.

“…However, land use changes can have significant impacts both on the locations of landslide triggering zones (Glade, 2003;Begueria, 2006;Reichenbach et al, 2014;Persichillo et al, 2017a) and on the connectivity of the mobilized sediments (Foerster et al, 2014;Lopez-Vicente et al, 2013. Thus, susceptibility scenarios of different land use distributions may allow the identification of land man-agement practices able to reduce the slope instability which can induce damages to roads.…”

Abstract. Landslides cause severe damage to the road network of the hit zone, in terms of both direct (partial or complete destruction of a road or blockages) and indirect (traffic restriction or the cut-off of a certain area) costs. Thus, the identification of the parts of the road network that are more susceptible to landslides is fundamental to reduce the risk to the population potentially exposed and the financial expense caused by the damage. For these reasons, this paper aimed to develop and test a data-driven model for the identification of road sectors that are susceptible to being hit by shallow landslides triggered in slopes upstream from the infrastructure. This model was based on the Generalized Additive Method, where the function relating predictors and response variable is an empirically fitted smooth function that allows fitting the data in the more likely functional form, considering also non-linear relations. This work also analyzed the importance, on the estimation of the susceptibility, of considering or not the sediment connectivity, which influences the path and the travel distance of the materials mobilized by a slope failure until hitting a potential barrier such as a road. The study was carried out in a catchment of northeastern Oltrepò Pavese (northern Italy), where several shallow landslides affected roads in the last 8 years. The most significant explanatory variables were selected by a random partition of the available dataset in two parts (training and test subsets), 100 times according to a bootstrap procedure. These variables (selected 80 times by the bootstrap procedure) were used to build the final susceptibility model, the accuracy of which was estimated through a 100-fold repetition of the holdout method for regression, based on the training and test sets created through the 100 bootstrap model selection. The presented methodology allows the identification, in a robust and reliable way, of the most susceptible road sectors that could be hit by sediments delivered by landslides. The best predictive capability was obtained using a model in which the index of connectivity was also calculated according to a linear relationship, was considered. Most susceptible road traits resulted to be located below steep slopes with a limited height (lower than 50 m), where sediment connectivity is high. Different land use scenarios were considered in order to estimate possible changes in road susceptibility. Land use classes of the study area were characterized by similar connectivity features. As a consequence, variations on the susceptibility of the road network according to different scenarios of distribution of land cover were limited. The results of this research demonstrate the ability of the developed methodology in the assessment of susceptible roads. This could give the managers of infrastructure information about the criticality of the different road traits, thereby allowing attention and economic budgets to be shifted towards the most critical assets, where structural and non-structur...
