• Lightweight and portable for easy transportation.
• Test time of two hours or less.
• Requires only 2.5 liters of water.
The Guelph Permeameter is a constant head permeameter that measures in-situ hydraulic conductivity. It is a simple to operate, portable unit that requires very little training to use. Only one person is needed to perform the test.
The method involves measuring the steady-state rate of water recharge into unsaturated soil from a cylindrical well hole, in which a constant head of water is maintained. Calculations are made to determine the hydraulic conductivity, soil sorptivity and soil matrix flux potential. Depending on the soil type, tests can take between 1/2 hour and 2 hours using only 2.5 liters of water.
