Detecting Porosity & Permeability

Effective porosity can be measured with electromagnetic induction probes. Hydraulic conductivity can be measured in-situ by observing water-level fluctuations in drill-holes. For a system at equilibrium, the system needs to be disturbed to produce fluid flow by either pumping water … Continue reading

Characterization of Porosity & Permeability

Porosity and permeability are closely related, so it is unsurprising that measuring the properties share common techniques that involve determining interconnected pore volume. Porosity Porosity (n) is measured as the ratio of the volume of voids within a material to … Continue reading

Porosity and Permeability

Porosity is the number of pores per unit of volume in soil. Porosity may decrease through packing or compaction, increase through dilation during shear, or change when fines are transported from one area to another. Materials with higher porosity have … Continue reading
