As the liquid (typically water) flows through the hole, the soil should erode and the hole will expand. The flow rate should be measured throughout the procedure. Directly after the test, the diameter of the hole should be measured. The hydraulic shear stress along the surface of the hole at time t can be calculated as: [1]
The test may be stopped if any of the following conditions are met: (1) a total of 50 blows have been applied in any one of the 15 cm (6 in) intervals, (2) a total of 100 blows have been applied over the total 45 cm (18 in) depth, or (3) there is no observed advance of the sampling tube during 10 successive blows.
