Is there a big difference between horizontal permeability and vertical permeability coefficient

. That is to say, the permeability coefficient of geosynthetics is broad. The vertical permeability coefficient is unique to geotextiles. The test methods of permeability coefficient and vertical permeability coefficient are similar.

For example, geotextile, geomembrane, soft water pipes, etc.. According to the direction of the water flow, the coefficient of permeability of the geotextile is measured

Geomembrane, composite geomembrane, geotextile, geogrid, geotextile, geotextile bags, etc. are called geosynthetics. The coefficient of permeability is a kind of soil properties;
