Abstract

As a network of researchers we release an open-access database (EUSEDcollab) of water discharge and suspended sediment yield time series records collected in small to medium sized catchments in Europe. EUSEDcollab is compiled to overcome the scarcity of open-access data at relevant spatial scales for studies on runoff, soil loss by water erosion and sediment delivery. Multi-source measurement data from numerous researchers and institutions were harmonised into a common time series and metadata structure. Data reuse is facilitated through accompanying metadata descriptors providing background technical information for each monitoring station setup. Across ten European countries, EUSEDcollab covers over 1600 catchment years of data from 245 catchments at event (11 catchments), daily (22 catchments) and monthly (212 catchments) temporal resolution, and is unique in its focus on small to medium catchment drainage areas (median = 43 km2, min = 0.04 km2, max = 817 km2) with applicability for soil erosion research. We release this database with the aim of uniting people, knowledge and data through the European Union Soil Observatory (EUSO).

Abstract

To gain a better understanding of the global application of soil erosion prediction models, we comprehensively reviewed relevant peer-reviewed research literature on soil-erosion modelling published between 1994 and 2017. We aimed to identify (i) the processes and models most frequently addressed in the literature, (ii) the regions within which models are primarily applied, (iii) the regions which remain unaddressed and why, and (iv) how frequently studies are conducted to validate/evaluate model outcomes relative to measured data. To perform this task, we combined the collective knowledge of 67 soil-erosion scientists from 25 countries. The resulting database, named ‘Global Applications of Soil Erosion Modelling Tracker (GASEMT)’, includes 3030 individual modelling records from 126 countries, encompassing all continents (except Antarctica). Out of the 8471 articles identified as potentially relevant, we reviewed 1697 appropriate articles and systematically evaluated and transferred 42 relevant attributes into the database. This GASEMT database provides comprehensive insights into the state-of-the-art of soil- erosion models and model applications worldwide. This database intends to support the upcoming country-based United Nations global soil-erosion assessment in addition to helping to inform soil erosion research priorities by building a foundation for future targeted, in-depth analyses. GASEMT is an open-source database available to the entire user-community to develop research, rectify errors, and make future expansions.

Abstract

Soil erosion can present a major threat to agriculture due to loss of soil, nutrients, and organic carbon. Therefore, soil erosion modelling is one of the steps used to plan suitable soil protection measures and detect erosion hotspots. A bibliometric analysis of this topic can reveal research patterns and soil erosion modelling characteristics that can help identify steps needed to enhance the research conducted in this field. Therefore, a detailed bibliometric analysis, including investigation of collaboration networks and citation patterns, should be conducted. The updated version of the Global Applications of Soil Erosion Modelling Tracker (GASEMT) database contains information about citation characteristics and publication type. Here, we investigated the impact of the number of authors, the publication type and the selected journal on the number of citations. Generalized boosted regression tree (BRT) modelling was used to evaluate the most relevant variables related to soil erosion modelling. Additionally, bibliometric networks were analysed and visualized. This study revealed that the selection of the soil erosion model has the largest impact on the number of publication citations, followed by the modelling scale and the publication's CiteScore. Some of the other GASEMT database attributes such as model calibration and validation have negligible influence on the number of citations according to the BRT model. Although it is true that studies that conduct calibration, on average, received around 30% more citations, than studies where calibration was not performed. Moreover, the bibliographic coupling and citation networks show a clear continental pattern, although the co-authorship network does not show the same characteristics. Therefore, soil erosion modellers should conduct even more comprehensive review of past studies and focus not just on the research conducted in the same country or continent. Moreover, when evaluating soil erosion models, an additional

Abstract

Anthropogenic impacts on rivers have increased significantly over the past ~150 years, particularly at the beginning of the industrial revolution. Among other signs, this impact is manifested through the addition of trace metals and metalloid elements to rivers. The Eure River watershed in France covers an area of 6017 km2 and is a major tributary of the Seine estuary. It is not exempt from anthropogenic pressures and has been exposed to significant metal discharges over the last 80 years. The average concentrations of metals (i.e., Cr, Co, Ni, Cu, Zn, Ag, Cd, Sb, and Pb), in suspended particulate matter currently transported by the river are high compared to the local geochemical background. Moreover, the lack of correlation between concentration variations and the hydrosedimentary behaviour of the Eure River suggests that the river is currently under anthropogenic pressure. Analysis of sediment cores indicate strong As contamination during the 1940s, Cr, Co, Ni, Cu, Zn, Ag, Cd, and Hg contamination during the 1960s and 1970s, and Sb and Pb contamination during the 1990s and 2000s. The enrichment factors calculation suggests that total anthropogenic pressure within the Eure River watershed since the 1940s was comparable or higher than those in many other French watersheds. An estimation of particulate metal flux in 2017 shows that the Eure River watershed contributed to 7, 8, 9, 10 and 16% of total inputs to the Seine estuary in Cr, Cu, Zn, Cd and Pb respectively. Moreover, the estimation of past theoretical flux indicates that during the 1990s the Eure River watershed was the main contributor of particulate Pb to the estuary. The use of Pb isotopes has revealed that this contamination was primarily of industrial origin.

Abstract

Water erosion is a serious concern in global land degradation leading to multiple consequences: loss of arable lands, siltation of streams, mudflows. In France, the Hauts-de-France region is the most affected area, and soil loss can exceed 10 t ha-1 yr-1. Although hydro-sedimentary processes have been widely studied by the scientific community, there is still a lack of knowledge in the understanding of the spatio-temporal variabilities. Additionally, the effectiveness of recent erosion control policies so far cannot be quantified. This study proposes an analysis of the spatio-temporal variability of sedimentary transfer at different scaling (1-1000 km²), and an initial assessment of the effectiveness of management policies within a northern France catchment (the Canche river, 1274 km²). A high-frequency monitoring station was implemented at the outlet of a Canche sub-catchment (the Pommeroye, 0.54 km²) to quantify the hydro-sedimentary transfer over two contrasted hydrologic years. According to our results, sediment yield varies from 29.4 to 70 t km-2 yr-1. 40% of the flux is exported during 3 major erosive events (out of 48 recorded) and the forcing parameters are related to the duration and the amount of rainfall. In this sub-catchment, the centimeter-scale spatial prediction of the hydro-sedimentary transfer was carried out using the new soil erosion model WATERSED (BRGM) and the effectiveness of an anti-erosion management plan was quantified. Our results validate the operability of the model in this context. For a given event, sediment transfer can reach 76 t km-2 yr-1 in agricultural plots and are strongly depending on the soil surface state. A significant reduction (up to 84%) of sedimentary transfer by the anti-erosion plan was also observed. At the scale of the Canche catchment, the use of chemical and spectrocolorimetric tracers in a mixing model (Sed_Sat tool; USGS) evaluated the contributions of the Canche tributaries and sediment sources contributions (i.e. channel banks and soils; 30-70% respectively). Significant spatio-temporal variations have been observed and the results show a potential positive impact of the recent management policies. This study also shows that new tracers related to the specific signature of magnetic particles are promising in the context to trace soil erosion. For further analyses, this data could be included in sediment fingerprinting approaches. Thus, this study based on several spatio-temporal modalities and the coupling of experimentation and modelling improves our understanding of the Canche hydro-sedimentary dynamics. It provides essential results to guide the future erosion control policies., L’érosion hydrique est un processus majeur de dégradation des sols dans le monde avec des conséquences multiples : perte de terres agricoles, envasement des cours d’eau, coulées boueuses. En France, la région Hauts-de-France est la zone la plus touchée par ces pertes en terres qui peuvent dépasser les 10 t ha-1 an-1. Si les processus à l’origine de ces transferts sédimentaires ont été largement étudiés par la communauté scientifique ces dernières années, il reste néanmoins des verrous liés aux variabilités spatio-temporelles. De plus, l’efficacité des politiques récentes de lutte contre l’érosion n’est pas quantifiée. Cette étude propose une analyse de la variabilité spatio-temporelle des transferts sédimentaires selon plusieurs échelles (1-1000 km²), et une première évaluation de l’efficacité des politiques d’aménagement au sein d’un bassin du Nord de la France (la Canche ; 1274 km²). Une station de mesure haute-fréquence, a été implémentée à l’exutoire d’un sous-bassin versant de la Canche (la Pommeroye ; 0,54 km²) pour quantifier les transferts hydro-sédimentaires sur deux années hydrologiques contrastées. Selon nos résultats, les transferts varient de 29,4 à 70 t km-2 an-1. 40% du flux est exporté au cours de 3 épisodes érosifs majeurs (sur 48 enregistrés) et les paramètres forçants sont liés à la durée d’un épisode pluvieux et la quantité de précipitations. Sur ce même bassin, la prédiction spatiale à l’échelle centimétrique des transferts hydro-sédimentaires a pu être effectuée via le nouveau modèle d’érosion des sols WATERSED (BRGM) et l’efficacité d’un plan d’aménagement de lutte contre l’érosion a été quantifiée. Nos résultats permettent de valider l’opérabilité du modèle sur ce territoire. Les transferts sédimentaires à l’échelle du parcellaire agricole peuvent atteindre les 76 t km-2 pour un évènement donné et sont influencés par l’état de surface du parcellaire agricole. Une réduction significative (jusqu’à 84%) des transferts par les aménagements d’hydraulique douce est également observée. A l’échelle du bassin de la Canche, l’utilisation de traceurs chimiques et spectrocolorimétriques dans un modèle de mélange (Sed_Sat ; USGS) a permis d’évaluer d’une part les contributions des affluents de la Canche et d’autre part les contributions des sols et des berges (respectivement 30-70%). Des variations spatio-temporelles significatives ont pu être observées et les résultats tendent à montrer un potentiel impact positif des politiques récentes d’aménagement du territoire. Cette étude montre également que de nouveaux traceurs liés à la signature spécifique des particules magnétiques sont particulièrement prometteurs dans ce contexte pour tracer un signal d’érosion des sols. A terme, ces données pourraient être incluses dans des approches sediment fingerprinting. L’analyse selon plusieurs modalités spatio-temporelles et le couplage expérimentation/modélisation améliore donc notre compréhension de la dynamique des transferts sédimentaires sur le bassin versant de la Canche. Cela fournit des résultats essentiels pour orienter les futures politiques de lutte contre l’érosion des sols.

Abstract

National audience; The Eure River (Normandie, France) is the main tributary of the Seine River downstream. Formerly the Martot Dam blocked the Eure River waters less than 1 km upstream the Eure-Seine Rivers confluence. But, in the context of the European Water Framework Directive (2000/60/EC), the French Authorities removed the Martot Dam in October 2017. A hydraulic annex (called the Martot Pond) is located ~300 m upstream the ex-location of the Martot Dam, wherein sediments are stored since several decades.The study aims to evaluate the dam removal impacts on (i.) re-suspension of contaminated sediments stored in the Martot Pond and the Eure River’s channel and (ii.) hydro-sedimentary transfers in Eure River.Concerning past transfers and sediments accumulation in the Eure River Watershed, sedimentary archives have been cored, before dam removal, at the Martot Pond and the Les Damps Pond (located 10 km upstream the latter). Dating of sedimentary cores for both ponds indicates a sedimentation rate around 1 cm y-1. Organic compounds (PAHs, PCBs and Organochlorine Pesticides) and Trace Metal Elements (TME) showed a wide contamination with highest concentrations evidenced during the 1950-1960’s and the 1990-2000’s. These variations of concentrations along cores can be associated with agricultural and industrial past of the Eure River Watershed and sources of contamination could be identified. Concerning actual transfers, Suspended Particulate Matter (SPM) are monthly sampled using Time-Integrated Mass-flux Sediments Samplers (TIMS Samplers). Suspended Particulate Matter sampling in the Eure River began before dam removal in two sites: between the Martot Dam and the Martot Pond and at Les Damps site. Particulate concentrations of organic compounds and TME allow us to determine (i.) actual SPM transfers quality (ii.) contaminants fluxes before, during and after dam removal and (iii.) contaminated sediments re-suspension from the Martot Pond and the Eure River’s channel.

Abstract

Excessive sediment discharge at karstic springs and thus, water treatment plants, can be highly disruptive. It is essential for catchment stakeholders and drinking water supplier to reduce the impact of sediment on potable water supply, but their strategic choices must be based on simulations, integrating surface and groundwater transfers, and taking into account possible changes in land use. Karstic environments are particularly challenging as they face a lack of accurate physical description for the modelling process, and they can be seen as a black-box due to the non-linearity of the processes generating sediment discharge. The aim of the study was to assess the sediment discharge variability at a water treatment plant according to multiple realistic land use scenarios. To reach that goal, we developed a new coupled modelling approach with an erosion-runoff GIS model (WaterSed) and a deep neural network. The model was used in the Radicatel catchment (106 km2 in Normandy, France) where karstic spring water is extracted to a water treatment plant. The sediment discharge was simulated for five designed storm projects under current land use and compared to three land use scenarios (baseline, ploughing up of grassland, eco-engineering, best farming practices). Daily rainfall time series and WaterSed modelling outputs extracted at connected sinkholes were used as input data for the deep neural network model. The model structure was found by a classical trial and error procedure, and the model was trained on two significant hydrologic years. Evaluation on a test set showed a good performance of the model (NSE = 0.82), and the application of a monthly-backward chaining nested cross validation revealed that the model is able to generalize on new datasets. Simulations made for the three land use scenarios suggested that ploughing up 33 % of grasslands would not increase significantly sediment discharge at the water treatment plant (5 % in average). In the opposite, eco-engineering and best farming practices will significantly reduce sediment discharge at the water treatment plant (respectively in the range of 10-44 and 24-61 %). The coupling of these two strategies is the most efficient since it affects the hydro-sedimentary production and transfer processes (decreasing sediment discharge from 40 to 80 %). The coupled modelling approach developed in this study offers interesting opportunities for sediment discharge prediction at karstic springs or water treatment plant under multiple land use scenarios. It also provides robust decision-making tools for land use planning and drinking water suppliers. [ABSTRACT FROM AUTHOR]
