Modeling fracture flow with a stochastic discrete fracture network: calibration and validation: 1. The flow model
M. C. Cacas,Emmanuel Ledoux,G. de Marsily,B. Tillie,A. Barbreau,E. Durand,B. Feuga,P. Peaudecerf +7 more
TL;DR: In this paper, a large-scale investigation of fracture flow was conducted in a granite uranium mine at Fanay-Augeres, France, and four types of data were collected: (1) geometry of the fracture network; (2) local hydraulic properties measured by injection tests in boreholes; (3) global hydraulic behavior from flow rate and piezometric head distribution at a 106 m3 scale; and (4) tracer tests performed at a scale of up to 40 m.
Journal ArticleDOI
Modeling fracture flow with a stochastic discrete fracture network: Calibration and validation: 2. The transport model
TL;DR: In this paper, the results of the tracer experiments are interpreted and a particle following coupled to the flow model, described in paper 1, is used to confirm the validity of the preliminary hydraulic calibration of the model and to validate further the approach used to simulate hydraulic and transport phenomena.
Journal ArticleDOI
Agriculture and groundwater nitrate contamination in the Seine basin. The STICS-MODCOU modelling chain.
Emmanuel Ledoux,Eric Gomez,Jean-Marie Monget,Christophe Viavattene,Pascal Viennot,Agnès Ducharne,Marc Benoit,Catherine Mignolet,Céline Schott,Bruno Mary +9 more
TL;DR: A software package is presented here to predict the fate of nitrogen fertilizers and the transport of nitrate from the rooting zone of agricultural areas to surface water and groundwater in the Seine basin, taking into account the long residence times of water and nitrate in the unsaturated and aquifer systems.
Journal ArticleDOI
River bank filtration: modelling of the changes in water chemistry with emphasis on nitrogen species
TL;DR: In this paper, a conceptual and numerical macroscopic model of the evolution of the water chemistry during bank-filtration in the case of an experimental site, part of a large well field (Seine river, France).
Journal ArticleDOI
Long term prospective of the Seine River System : Confronting climatic and direct anthropogenic changes
Agnès Ducharne,Charles Baubion,Nicolas Beaudoin,Marc Benoit,Gilles Billen,Nadine Brisson,Josette Garnier,H. Kieken,Sophie Lebonvallet,Emmanuel Ledoux,Bruno Mary,Catherine Mignolet,X. Poux,Emmanuelle Sauboua,Céline Schott,Sylvain Théry,Pascal Viennot +16 more
TL;DR: The results of this numerical exercise indicate that the potential changes to the Seine River system during the 21st century will not lead to severely degraded water quality.
