“…Therefore, site-specific management methods need to be evaluated and developed for successful functioning of the VFS. These important and various factors affecting VFS performance have to be considered by the Vegetated Filter Strip model (VFSMOD), developed by Munoz-Carpena and Parsons [2]. The VFSMOD system is a desktop-based model, and it requires many input data as it considers various conditions of field and VFS.…”

“…As such, the model can be used to predict sediment transport through VFS, simulates outflow and sediment reduction in VFS based overland flow hydraulics and infiltration into the soil layer [15]. The VFSMOD was successfully tested with natural events with North Carolina Piedmont data [2] and Coastal Plain [16]. Researchers at the University of Guelph, in Canada, have tested the model with field experimental data [17].…”

“…Vegetative filter strip (VFS) has been increasingly used because of its environment-friendly and economical aspects. The VFS is designed to remove not only sediment, but also other pollutants such as nutrients and pathogens from surface water runoff by filtration, deposition, infiltration, adsorption, absorption, decomposition, and plant uptake [2]. Reducing the velocity of runoff from source areas such as farmland or agricultural areas, the VFS causes sediment to be deposited.…”

“…Especially, desktop-based models require users to prepare many kinds of input data, which is sometimes very difficult for even experienced users. The Vegetated Filter Strip model (VFSMOD), developed by Munoz-Carpena and Parsons [2], is a desktop-based model. Thus it requires many various input data as it considers various conditions of upland field and the VFS.…”

Abstract:In recent years, Non-Point Source Pollution has been rising as a significant environmental issue. The sediment-laden water problem is causing serious impacts on river ecosystems not only in South Korea but also in most countries. The vegetative filter strip (VFS) has been thought to be one of the most effective methods to reduce the transport of sediment to down-gradient area. However, the effective width of the VFS first needs to be determined before VFS installation in the field. To provide an easy-to-use interface with a scientific VFS modeling engine, the Web GIS-based VFSMOD system was developed in this study. The Web GIS-based VFSMOD uses the UH and VFSM executable programs from the VFSMOD-w model as core engines to simulate rainfall-runoff and sediment trapping. To provide soil information for a point of interest, OPEN ACCESSWater 2013, 5 1195 the Google Map interface to the MapServer soil database system was developed using the Google Map API, Javascript, Perl/CGI, and Oracle DB programming. Three modules of the Web GIS-based VFSMOD system were developed for various VFS designs under single storm, multiple storm, and long-term period scenarios. These modules in the Web GIS-based VFSMOD system were applied to the study watershed in South Korea and these were proven as efficient tools for the VFS design for various purposes.

“…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.

This paper presents the decoupled hydrological discretization (DHD) scheme for solving the shallow water equations in hydrological applications involving surface runoff in rural and urban basins. The name of the scheme is motivated by the fact that the three equations which form the two-dimensional shallow water system are discretized independently from each other and thus, the numerical scheme is decoupled in a mathematical sense. Its main advantages compared to other classic finite volume schemes for the shallow water equations are its simplicity to code and the lower computational cost per time step. The validation of the scheme is presented in five test cases involving overland flow and rainfall-runoff transformation over topographies of different complexity. The scheme is compared to the finite volume scheme of Roe (1986), to the simple inertia formulation, and to the diffusive wave model. The test cases show that the DHD scheme is able to compute subcritical and supercritical flows in rural and urban environments, and that in overland flow applications it gives similar results to the second-order scheme of Roe with a lower computational cost. The results obtained with the simple inertia and diffusive wave models are very similar to those obtained with the DHD scheme in rural basins in which the bed friction and topography dominate the flow hydrodynamics but they deteriorate in typical urban configurations in which the presence of supercritical flow conditions and small-scale patterns boost the relevance of the inertial terms in the momentum equations.
