WebThe effective porosity of saturated porous media is a funda- mental hydrogeological parameter for modeling the fate and transport of dissolved-phase contaminants in the subsurface. Reliable modeling is highly dependent on accurate character- ization of effective porosity. WebA subsurface northeast-trending bedrock “step” marks the edge of the deeper alluvial aquifer to the south.
