The jet erosion test (JET) and the hole erosion test (HET) are two tests used to determine soil erodibility classification, and results are commonly interpreted by two distinct methods. A new method based on fluid energy dissipation and on measurement of the eroded mass for interpreting the two tests is proposed. Different fine-grained soils, covering a large range of erodibility, are tested. It is shown that, by using common methods, the erosion coefficient and average critical shear stress…

Measuring Soil Erodibility Using a Laboratory “Mini” JET
Abstract. Typically soil erodibility is quantified using an excess shear stress equation, dependent on two major soil parameters: the critical shear stress (I„ c ) and the erodibility coefficient (k
The Hole Erosion Test: A Comparison of Interpretation Methods
The hole erosion test (HET) is widely performed for determining soil erosion characteristics; viz. critical shear stress, erosion rate coefficient, and erosion rate index. Refinements to
A Scour Depth Approach for Deriving Erodibility Parameters from Jet Erosion Tests
Abstract. Typically the erosion rate of cohesive soils is modeled using the excess shear stress equation, which includes two soil parameters: the erodibility coefficient (k d ) and the critical shear
An alternative method for interpreting JET erosion test (JET) data: Part 2. Application

Effect of soil composition on piping erosion of earthen levees
ABSTRACT Internal erosion processes due to piping in an earthen levee built in a laboratory flume are reported in this paper. Different sand, silt and clay mixtures are used for constructing the
Assessing the susceptibility of gap-graded soils to internal erosion: proposition of a new experimental methodology
Suffusion and global backward erosion are two of the main internal erosion processes in earth structures and their foundations which may increase their failure risk. For other processes of internal

Investigation of interface erosion rate by Jet Erosion Test and statistical analysis
ABSTRACT Erosion is one of the main causes of instabilities within hydraulic earth structures. Two types of erosion can be distinguished: suffusion and interface erosion. This paper deals with the

Excess stress parameters, critical shear stress (τ c ) and erodibility coefficient (k d ), for degrading channels in the loess areas of the midwestern USA are presented based on in situ jet-testing
The scaling law in the hole erosion test with a constant pressure drop
A process called “piping”, which often occurs in the soil at dams, levees and dykes, involves the formation and development of a continuous tunnel between the upstream and downstream ends. The hole
