Περίληψη | A two-dimensional numerical transport model is developed to determine the effect of aquifer anisotropy and heterogeneity
on mass transfer from a dense nonaqueous phase liquid (DNAPL) pool. The appropriate steady state groundwater flow equation
is solved implicitly whereas the equation describing the transport of a sorbing contaminant in a confined aquifer is solved
by the alternating direction implicit method. Statistical anisotropy in the aquifer is introduced by two-dimensional, random
log-normal hydraulic conductivity field realizations with different directional correlation lengths. Model simulations indicate
that DNAPL pool dissolution is enhanced by increasing the mean log-transformed hydraulic conductivity, groundwater flow velocity,
and/or anisotropy ratio. The variance of the log-transformed hydraulic conductivity distribution is shown to be inversely
proportional to the average mass transfer coefficient.
