【 摘 要 】

Anisotropic and heterogeneous flow in unsaturated porous media is dependent on saturation conditions, and currently there exist limited options that adequately model this phenomenon. The phenomenon of lateral spreading commonly attributed to anisotropy can move contaminants beyond compliance boundaries at unexpected velocitites essentially bypassing large regions of the subsurface.
