WebPermeability of soils and Factors affecting permeability. Ease with which the water can flow through soil is known as permeability. Larger the pores more the permeability and vice versa. Gravel would have more permeability compared to the sand, silt and clay. Flocculated structure would have more permeability than the dispersed structure.

Under the impact of rain the soil slumps, soil pores collapse or are filled by dispersed clay particles. This results in a reduction in soil pore space. The consequence of this depends on whether the soil topsoil, subsoil or both are sodic. the people s couch
