Abstract
It has been widely reported that biofilm growth changes the hydraulic parameters in porous media. While the impact upon reduction of hydraulic conductivity has been widely explained and modeled, this has not been the case for the reported order(s) of magnitude increase in dispersion coefficient even when a minute percentage of biofilm is formed, and despite the effect of biofilm growth is to reduce specific discharge, producing a somewhat counter intuitivitive result. We develop here a simple ye...
