“…[4] Although a significant number of researchers have examined pore-scale dissolution [e.g., Békri et al, 1995;Daccord et al, 1993aDaccord et al, , 1993bFredd and Fogler, 1998;Paraskeva et al, 2000] and precipitation [e.g., Borisova and Adler, 2005;Maddinelli, 1998;Sallès et al, 1993;F. Golfier et al, Comparison of theory and experiment for a tworegion solute transport model, submitted to Advances in Water Resources, 2007, hereinafter referred to as Golfier et al, submitted manuscript, 2007] processes in porous media, the numerical tools required to handle such dynamic processes on the pore scale have only just begun to be developed [e.g., Kang et al, 2003;Magnico, 2000;Golfier et al, submitted manuscript].…”
