Permeability equation groundwater

WebThe permeability index (PI) is one of the most important indicators of groundwater suitability for agricultural activities. It is a measure of the ability of soil to move water (permeability). It correlates sodium, calcium, magnesium, and bicarbonate concentrations in soil, which are influenced by long-term irrigation practices (equation ( 15 )).
