Pressure conditions in the hole erosion test
Original language description
The hole erosion test (HET) is used in the study of soil erosion in the case of what is known as "piping" when concentrated leaks occur. The HET anables the determination of soil erosion characteristics such as the critical shear stress along the pre-formed hole (pipe) and the coefficient of soil erosion. Normally, in the HET, the hydraulic gradient is determined from the difference between the piezometric heads measured at the inflow and outflow chambers (upstream and downstream of the soil specimen). Hydraulic analysis shows that such measurements ingnore losses at the entrance and exit of the hole, causing the overstimation of the hydraulic gradient along the lenght of the hole, and thus the calculated shear stress.
