“…The retention of nutrients has been simulated using physically based approaches. Those process based models, such as REMM (Riparian Ecosystems Management Model) (Inamdar et al, 1999) or VFSMOD (Vegetative Filter Strip MODel) (Munoz-Carpena and Parsons, 2005;Munoz-Carpena et al, 1999) have been used at a local scale but require exhaustive data input which, on a European scale, becomes prohibitive. There is thus a need to develop new tools that can be applied at a larger scale in order to identify areas where riparian zones need to be maintained or restored in order to improve or maintain good water quality.…”

Key-words:Riparian buffer zone, nutrient load reduction, buffer capacity, buffer permeability Riparian buffer zones play an important role as nutrient pollution controls for rivers. We provide a harmonized, explorative quantitative and spatially explicit continental assessment of nitrogen and phosphorus potential retention in riparian buffer zones along the European river network CCM2 (Catchment Characterization and Modellling). Diffuse emissions of nutrients from fertilized cropland and pasture, based on a statistical model (GREEN (Geospatial Regression Equation for European Nutrient Losses)), are partitioned into surface and subsurface flow pathways based on the innovative SUGAR (Surface water/Groundwatercontribution index) index. Surface flow N and P emissions are assumed to undergo attenuation as a function of riparian buffer width. In contrast, the attenuation of subsurface flow emissions and emissions from wetlands is assumed to be independent of buffer width. Buffer attenuation follows a nutrient-specific negative exponential decay function. For the study area, we estimate retention in surface runoff emissions of 33% for nitrogen and 65% for phosphorus. The results represent a valuable data source for water basin management with respect to water quality improvement, in particular buffer zone restoration. RÉSUMÉ Réduction des charges d'azote et de phosphore dans les rivières européennes par les zones tampons riveraines Mots-clés :Zone tampon riveraine, réduction de la charge en éléments nutritifs, capacité tampon, perméabilité de zone tampon Les zones tampons riveraines jouent un rôle important dans la régulation de la pollution en éléments nutritifs pour les cours d'eau. Nous proposons une éva-luation harmonisée, exploratoire quantitativement et spatialement explicite de la rétention potentielle d'azote et de phosphore dans les zones tampons riveraines le long du réseau fluvial européen CCM2. Les émissions diffuses de nutriments provenant des terres cultivées fertilisées et des pâturages, basées sur un modèle statistique (GREEN), sont réparties en écoulements de surface et souterrain, voies basées sur l'indice novateur SUGAR. Les émissions de surface de N et de P sont supposées subir une atténuation en fonction de la largeur de la bande riveraine. En revanche, l'atténuation des émissions de flux de subsurface et les émissions des zones humides est supposée être indépendante de la largeur du tampon. L'atténuation dans la zone tampon suit une fonction négative de décroissance exponentielle spécifique du nutriment. Pour la zone d'étude, nous estimons la rétention des émissions de ruissellement à 33 % pour l'azote et 65 % pour le phosphore.

“…An extensive range of hydrological models has been developed with different applications in relation to the riparian zone. Inamdar et al (1999aInamdar et al ( , 1999b developed the Riparian Ecosystem Management Model (REMM) to estimate riparian denitrification. Subsequently, the REMM has been coupled with spatial hydrological models, such as The Groundwater Loading Effects of Agricultural Management System (GLEAMS) and The Soil and Water Assessment Tool (SWAT).…”

Abstract. One feature of riparian zones is their ability to significantly reduce the nitrogen loads entering streams by removing nitrate from the groundwater. A novel GIS model was used to prioritise riparian rehabilitation in catchments. It is proposed that high-priority areas are those with a high potential for riparian denitrification and have nearby land uses that generate high nitrogen loads. For this purpose, we defined the Rehabilitation Index, which is the product of two other indices, the Nitrate Removal Index and the Nitrate Interception Index. The latter identifies the nitrate contamination potential for each raster cell in the riparian zone by examining the extent and proximity of agricultural urban land uses. The former is estimated using a conceptual model for surface-groundwater interactions in riparian zones associated with middle-order gaining perennial streams, where nitrate is removed via denitrification when the base flow interacts with the carbon-rich riparian sediments before discharging to the streams. Riparian zones that are relatively low in the landscape, have a flat topography, and have soils of medium hydraulic conductivity are most conducive to denitrification. In the present study, the model was implemented in the Tully-Murray basin, Queensland, Australia, to produce priority riparian rehabilitation area maps.

“…So, a number of different approaches have been used to develop denitrification models in N cycling. Most models are site specific, and do not apply to the basin scale, such as the DNDC model (Li et al, 2000;Liu et al, 2006), the EPIC model (Sharply and Williams, 1990), the SWAP model (van Dam et al, 1997) and REMM model (Inamdar et al, 1999). In fact, there exists no model that can describe the riparian soil denitrification process at an appropriate and sufficiently high spatial scale.…”
