WebThere are two general types of permeability test methods that are routinely performed in the laboratory: 1) Constant head test method. 2) Falling head test method. The constant head test method is used for permeable soils (k>10-4 cm/s) and the falling head test is mainly used for less permeable soils (k<10-4 cm/s). 3. personal ledger app
