Why Clay Has High Aquifer Porosity But Low Permeability

“Why does clay have high porosity but low permeability?”

Clay has a highly porous structure, meaning that there are a lot of holes in its structures. However, these holes are small and not well connected to each other. This means water gets stuck in these small holes due to friction and stickiness. This leads to a low permeability. This is Why Clay Has High Aquifer Porosity But Low Permeability.
