Analytical solution for conservative solute transport in one-dimensional homogeneous porous formations with time-dependent velocity / Kumar Singh, Mritunjay in Journal of engineering mechanics, Vol. 135 N° 9 (Septembre 2009) 

Public ISBD [article]  in Journal of engineering mechanics > Vol. 135 N° 9 (Septembre 2009) . - pp. 1015-1021 Titre : Analytical solution for conservative solute transport in one-dimensional homogeneous porous formations with time-dependent velocity Type de document : texte imprimé Auteurs : Kumar Singh, Mritunjay, Auteur ; Singh, Vijay P., Auteur ; Singh, Premlata, Auteur Article en page(s) : pp. 1015-1021 Note générale : Mécanique appliquée Langues : Anglais (eng) Mots-clés : Groundwater  pollution  Nonpoint  pollution  Point  pollution  Aquifers  Unsteady  flow  Solutes  Analytical  techniques. Résumé : The space-time variation in contaminant concentration in unsteady flow in a homogeneous finite aquifer subjected to point source contamination is analytically derived under two conditions: (1) the flow velocity in the aquifer is of sinusoidal form; and (2) the flow velocity is an exponentially decreasing function. The analytical solution is illustrated using an example. Analytical solutions are perhaps most useful for benchmarking numerical codes and solutions.
