Hydraulic properties of vesicular basalt

Abstract

Laboratory experiments were conducted on vesicular basalt cores to estimate hydraulic properties. Properties included dry bulk density, effective porosity, skeletal density, saturated hydraulic conductivity and determination of moisture characteristic curves. Unsaturated hydraulic properties estimated included hydraulic conductivity and diffusivity as a function of matrix suction. Infiltration tests were run on a larger block of the same basalt. Infiltration curves were developed and saturated hydraulic conductivity estimated.
