“…The research conducted in the Cànyoles river watershed showed that the road embankments are an efficient source of water and sediment under intense thunderstorms 12962 as observed in previous studies in the same region (Cerdà, 2007), and in other regions of the world (see review by Navarro-Hevia et al, 2015). We found that within the plots runoff connectivity is very high, as demonstrated by the short time between ponding and runoff initiation and between the time to runoff and discharge at the runoff outlet.…”

Abstract. Road and railway infrastructure increased in the Mediterranean region during the last three decades. This included the building of embankments, which are assumed to be a~large source of sediments and runoff. However, little is known about soil erosion rates, the factors that control them, and the processes that contribute to detachment, transport and deposition of sediments from road and railway embankments. The objective of this study was therefore to assess the impacts of road and railway embankments as a source of sediment and water, and compare them to other land use types (citrus plantations and shrublands) representative of the Cànyoles watershed to evaluate the importance of road embankments as a~source of water and sediment under high magnitude low frequency rainfall events. Sixty rainfall experiments (1 m2 plots; 60 min duration; 78 mm h−1 rainfall intensity) were carried out on these land use types: 20 on two railway embankments (10 + 10), 20 on two road embankments (10 + 10), and 10 on citrus and 10 on shrubland. Road and railway embankments were characterized by bare soils with low organic matter and high bulk density. Erosion processes were more active in road, railway and citrus plots, and null in the shrublands. The non-sustainable soil erosion rates of 3 Mg ha−1 y−1 measured on the road embankments were due to the efficient runoff connectivity plus low infiltration rates within the plot as the runoff took less than one minute to reach the runoff outlet. Road and railway embankments are both an active source of sediments and runoff, and soil erosion control strategies must be applied. The citrus plantations also act as a~source of water and sediments (1.5 Mg ha−1 y−1), while shrublands are sediment sinks, as no overland flow was observed due to the high infiltration rates.

“…Despite the low contribution of unpaved roads to sediment obtained in this study (16 ± 10%), they represent perennial landscape features, and their construction should therefore be planned in the framework of integrated soil erosion control programs. The high soil erosion and sediment yield rates in unpaved roads should be take into account when designing and constructing road and railway cuts, because it is very important for infrastructure maintenance, as well as for soil formation, water protection, vegetation establishment and controlling land degradation (Seutloali and Beckedahl, ; Navarro‐Hevia et al , ). Moreover, unpaved road material can also contain considerable amounts of heavy metals like Pb, Cu, Cd and Zn, which are present in gasoline type fuels, tyre and brake pad wear, oils, lubricants and grease transport (Trujillo‐González et al , ).…”

Tracing Sediment Sources Using Mid‐infrared Spectroscopy in Arvorezinha Catchment, Southern Brazil

The widespread adoption of the sediment fingerprinting approach to guide catchment management has been limited by the cost and the difficulty to prepare and process samples for geochemical and radionuclide analyses. Spectral properties have recently been shown to provide a rapid and cost‐efficient alternative for this purpose. The current research objective was (i) to quantify the sediment source contributions in a 1∙19‐km2 rural catchment of Southern Brazil by using mid‐infrared (MIR) spectroscopy and (ii) to compare these results with those obtained with geochemical approach and near‐infrared and ultraviolet–visible spectroscopy methods. The sediment sources to discriminate were cropland surface (n = 20), unpaved roads (n = 10) and stream channel banks (n = 10). Twenty‐nine suspended sediment samples were collected at the catchment outlet during nine significant flood events. The sources could be distinguished by MIR spectroscopy. Cropland and channel bank sources mainly differed in their clay mineral contents, but their similar organic matter content complicated the MIR‐model predictions. Unpaved road contributions were discriminated from the other sources by their lower organic carbon content. When the results of the current research based on MIR spectroscopy are compared with those obtained using other sediment fingerprinting approaches, based on geochemistry and near‐infrared and ultraviolet–visible spectroscopy, an overestimation of channel banks contribution and an underestimation of cropland and unpaved road contributions is found. These results suggest that MIR spectroscopy can provide a useful tool that is non‐destructive, rapid and cheap for tracing sediment sources in rural catchments and for guiding the implementation of soil and water conservation measures.

“…In particular, it has become apparent that the internal functioning of the catchment, especially connections between different spatial units (e.g. grass strips, field boundaries or roads), plays a crucial role in the understanding of runoff and sediment transfers (Rose et al, 2003;Rodríguez-Blanco et al, 2013;Akram et al, 2014;Navarro-Hevia et al, 2015). It is therefore necessary to better understand phenomena around these specific spots in order to better represent the whole-system behaviour.…”

Intensive agricultural practices on sensitive soils induce high erosion rates in central Belgium. Expert-rules models quantify runoff and erosion at catchment scale, avoiding over-parameterization, and can include some direct or indirect connectivity features. The aim of this article is to test the ability of an expert-based model, LandSoil, to quantify runoff and to locate erosion and sedimentation areas in a small cultivated loamy catchment in Belgium during the years 2014, 2015 and 2016. Spatialized data are important for assessing model outputs and the erosive response. Measurements of runoff and observation of spatial erosion/deposition patterns, especially around major connectivity points, permitted an assessment of the reliability of the model results. Runoff modelling gave contrasting results (good linear adjustment at the outlet of the 83 ha sub-catchment (point 1): r 2 of 0.96, Nash-Sutcliffe criterion of 0.95; less good at the outlet of the 3.9 ha sub-catchment (point 2): r 2 of 0.28, Nash-Sutcliffe criterion of-0.47). For point 2 the poor results are explained by the very few runoff events observed, a scaling effect and the small area with a single land use. Graduated rulers demonstrate that the model is able to provide a coherent pattern of erosion/deposition. The study highlights great sensitivity to the effect of land use, land allocation, landscape design and slope gradients. Grass strips induce deposition of eroded particles when slopes are gentle (< 2%). Woodland strips decrease connectivity by being in the stream but deposit thinner sediment layers. Field boundaries have a role in the transport, but not really the quantity, of sediments. This model validation in the Belgian loess context allows us to use LandSoil in other similar environments in order to estimate the effects of landscape management scenarios.
