"WebThe constant head permeameter is useful for measuring K of samples with higher values of hydraulic conductivity. When K is low, it is difficult to establish a constant flow rate over a relatively short time interval (minutes-hours), so instead, a falling head permeameter is used. In this method the water levels and flow rates change over time. " - Constant head permeameter
