What Is a Permeameter?

Disk permeameter is a device used in the field to measure soil infiltration and water permeability with large pores or preferential flow. Its measurement area is smaller than the double ring method, and it saves time, labor, and water. It can measure about 10 points a day. In principle, it can measure the saturated hydraulic conductivity of the soil layer at any depth above the groundwater level and can eliminate soil cracks. The effect of large pores such as wormholes, earthworm holes and root holes on the determination. ^[1]
