Analytical solution for two-dimensional solute transport in finite aquifer with time-dependent source concentration / Mritunjay Kumar Singh in Journal of engineering mechanics, Vol. 136 N° 10 (Octobre 2010) 

Public ISBD [article]  in Journal of engineering mechanics > Vol. 136 N° 10 (Octobre 2010) . - pp.1309-1315 Titre : Analytical solution for two-dimensional solute transport in finite aquifer with time-dependent source concentration Type de document : texte imprimé Auteurs : Mritunjay Kumar Singh, Auteur ; Premlata Singh, Auteur ; Singh, Vijay P., Auteur Année de publication : 2010 Article en page(s) : pp.1309-1315 Note générale : Mécanique appliquée Langues : Anglais (eng) Mots-clés : Solutes  Groundwater  pollution  Aquifers  Analytical  techniques. Résumé : Using the Hankel Transform Technique, an analytical solution is derived for two-dimensional solute transport in a homogeneous isotropic aquifer. The aquifer is subjected to time-dependent point source contamination. The solution is derived under two conditions: (1) the flow velocity in the aquifer is a sinusoidally varying function and (2) the flow velocity is an exponentially decreasing function. Initially the aquifer is assumed solute free. The analytical solution is illustrated using an example.
