“…These factors are captured within the Universal Soil Loss Equation (USLE), which has been used within a GIS framework to estimate the erosion risk of watershed areas in several previous studies (Yitayew et al 1999;Lee 2004;Lu et al 2004). These studies do not consider sediment delivery, but others have combined the USLE technique with a sediment delivery model (SEDD), incorporating the sediment delivery ratio, in order to estimate the amount sediment that actually reaches watercourses (Ferro et al 1998;Fernandez et al 2003;Fu et al 2006). Since quality GIS-based wetland information is scarce and the analysis of wetlands is difficult using prefabricated models, many erosion risk studies are forced to ignore wetland areas.…”

"Canada's multilayered wetland policies promote the preservation of "significant" wetlands, but the criteria for identifying these wetlands are not clearly defined partially because wetlands are a source of multiple ecological outputs, such as abating sediment and providing wildlife habitat. This study adapts a GIS-based, hydrologic, and economic model to examine the trade-offs between agricultural interests and ecological benefits in the Eramosa Watershed, located in southwestern Ontario, Canada. While preserving a wetland enhances both water quality and wildlife habitat goals, and the costs of preservation increase at an increasing rate as expected, the ranking of wetlands, and so the choice of "significant" wetlands, varies considerably depending upon the wetland benefit chosen as the policy goal. The trade-off between wetland benefits and drainage is diminished if there is an alternative means to abate sediment. Since conservation tillage is a lower cost means of improving water quality than wetland preservation, its inclusion can achieve comparable environmental benefits at decreased agricultural cost."

The paper presents some results of the study of natural-anthropogenic erosion network formation on open slope in the upper Oka basin (Orel region). On the example of 2014, it is shown that intensive precipitation (daily amount is comparable to the multi-year-averaged monthly amount), fell during the period when the field is not protected by vegetation (end of June and end of September, 2014), formed a breakup-furrow-based stream network. The satellite image collected on July 7, 2014 helped to detect this fact. Measurements of activity of the Chernobyl origin cesium-137 in the soil of thalwegs of the ancient ravines and modern streams (formed by the heavy rains of the summer and autumn of 2014 in breakup furrows), made it possible to estimate dependencies between cesium-137 activity and morphometric parameters of relief (catchment area and profile curvature) estimated by means of GIS for ancient ravines and modern streams. As a result of comparative analysis, it was found that the soil runoff on the Northern aspect slope in modern streams exceeds the runoff in the ancient ravines for more than 20 % (up to 50 %), while the values of catchment area are comparable. Soil runoff in modern streams can be predicted using the dependencies obtained for ancient ravines (applying corresponding raising factors) if June-September satellite imagery and precipitation monitoring data are available. Soil runoff in the tracks of agricultural machinery (with the 20 % evaluation error) can be estimated using equations obtained for inter-ravine surfaces. Where streams cross ancient ravines, calculation of soil washout must be performed by dependencies obtained for ancient ravines.

“…have increased the attractiveness of a simple parametric soil erosion model, like the universal soil loss equation, USLE (Wischmeier & Smith, 1965) or its revised version, RUSLE (Renard et al, 1994) coupled with a Sediment Delivery Distributed (SEDD) approach (Ferro & Porto, 2000). Furthermore, at present, the physically-based models give sediment yield estimates with a reliability comparable to those obtained by the RUSLE (Bingner, 1990;Risse et al, 1993;Renard et al, 1994) coupled with a spatial disaggregation criterion of sediment delivery processes (Ferro & Minacapilli, 1995;Ferro, 1997;Ferro et al, 1998c;Ferro & Porto, 2000).…”

Because the properties of eroded soil affect the deposition phenomena and transport capacity of chemical materials by eroded particles, recent research is trying to link the grain-size distribution of the eroded sediment to that of the original soil in order to explain the enrichment of chemical content of the sediment with the respect to the parent soil. In this study, the spatial distribution of nitrogen, phosphorus and total organic carbon was firstly deduced using the measurements carried out in 47 soil samples distributed over a forested basin together with a kriging interpolation method. Then the load of each chemical was calculated at morphological unit and basin scales using the above-mentioned spatial distributions and sediment yield values calculated by the SEDD (SEdiment Delivery Distributed) model, which couples the universal soil loss equation with a spatial disaggregation criterion of sediment delivery processes. Finally, at basin scale, a new expression of the enrichment ratio of a given chemical was applied.Key words chemical enrichment ratio; chemical transport; experimental basin; forested basin; geographical information systems; sediment yield; soil erosion; universal soil loss equation Processus de production sédimentaire et transport chimique dans un petit bassin versant forestierRésumé Puisque les propriétés d'un sol érodé conditionnent les processus de dépôt et la capacité de transport d'éléments chimiques par les particules érodées, une recherche récente essaye de mettre en relation la distribution granulométrique du sédiment érodé avec celle du sol originaire pour expliquer l'enrichissement du contenu chimique du sédiment par rapport au sol originaire. Dans cette étude, la distribution spatiale de l'azote, du phosphore et du carbone organique total a été initialement déduite de mesures effectuées sur 47 échantillons de sol répartis sur un bassin versant forestier et grâce à une méthode d'interpolation par krigeage. Ensuite, la charge de chaque élément chimique a été calculée aux échelles de l'unité morphologique et du bassin versant en utilisant les distributions spatiales préalablement mentionnées ainsi que les valeurs d'apports solides calculées par le modèle SEDD (Sediment Deliery Distributed) qui couple l'équation universelle de perte de sol et un critère de désagrégation spatiale des processus de production sédimentaire. Finalement, à l'échelle du bassin versant, une nouvelle expression du rapport d'enrichissement en un élément chimique donné a été appliquée.
