Stochastic evaluation of mixing-controlled steady-state plume lengths in two-dimensional heterogeneous domains

► Rigorous stochastic analysis of lengths of mixing-controlled plumes at steady state in two-dimensional aquifers ► Derivation of full statistical distributions of plume lengths ► Most important source of uncertainty is caused by uncertainty of volumetric flux through the source. ► Different parameterizations of local-scale transverse dispersion results in different mean plume lengths.
