This test is necessary for drainage application.
The permeameters can be of parallel flow or radial flow type. In either
case, flow occurs along the plane of the permeamatre. In the apparatus, flow
occurs radically outwards, from a central hole to the periphery of a
circular specimen. The transmissivity is defined as the volumetric rate of
flow per unit width of geotextile and unit hydraulic head.
