Infiltration rates of soils vary widely and are affected
by subsurface permeability as well as surface intake rates. Soils
are classified into four HSGs (A, B, C and D) to indicate the minimum
infiltration rates, which are obtained for bare soil after prolonged

or conservation district offices. Soils become less permeable as the
HSG varies from A to D.
