“…For a symmetric distribution of data, a value of 3 for kurtosis is generally expected [ 61 ]. A value greater than 3 shows positive kurtosis whereas a value lower than 3 shows negative kurtosis, representing light-tailed top peaked distribution and heavy-tailed flatter distribution, respectively [ 2 ]. The value of kurtosis for the K factor in this study was −0.075, thus indicating negative kurtosis.…”

“…Soil erosion is an indigenous geological phenomenon of separation and transportation of soil particles from their origin, and their accumulation either onsite or offsite [ 1 , 2 ]. Soil erosion induced by excessive precipitation and augmented surface runoff together with anthropogenic inference such as urbanization, deforestation, and agriculture lead to land degradation, reduced quality and quantity of arable land, enhanced river sedimentation, and prompting stern geological hazards [ [3] , [4] , [5] ].…”

“…Soil erodibility, typically termed as the K-factor, is an inherent property of soil that determines its resistance to both detachment and transport [ 2 ]. K factor is a crucial marker of soil erosion susceptibility [ 12 ] and is a vital parameter employed in various soil erosion estimation models influencing the extent of soil loss [ 13 , 14 ].…”

“…Modern penetration devices have become very sophisticated in recent years and are supplied with state-of-the-art sensors that are capable of measuring water pressure, moisture content, seismic parameters, and others. Many studies have confirmed direct and indirect correlations between these measurements and some geotechnical parameters [11][12][13]. These parameters include moisture content, plasticity, index properties, and shear strength.…”

Use of the Dynamic Cone Penetrometer in Compacted Clay–Sand Layers

The ASTM D6951 suggests a test method using the dynamic cone penetrometer (DCP) for the assessment of shallow pavement strength. This study is dedicated to evaluating a similar test method to be used for fine-grained clay–sand mixtures, which are commonly used to construct liners and fluid barriers. The liner layers include clay, which is water-sensitive. The shear strength of the liners depends mainly on the composition and proportions of the mixtures adopted. A series of tests were conducted in the laboratory for compacted clay–sand mixtures, including 5% and 10% bentonite material. The responses to advancing a dynamic probe into compacted material at three various moisture conditions—namely, the optimum, dry of optimum, and wet of optimum water contents—are investigated. The penetration profiles are compared for the two clay content levels selected and for three moisture state conditions. The clay–sand liners support vehicles and vibratory compactors during construction and when waste material is placed. The shear strengths of the mixtures are evaluated in the laboratory using direct shear tests. From the results obtained in this investigation, general guidelines and recommendations are presented to help with the efficient assessment of liners consisting of clay–sand mixtures. A cheap and quick approach to assess the density and shear strength of landfill liners or clay–sand layers can be achieved using a hand-held dynamic cone penetrometer. The state of moisture during compaction was found to influence the DCP results. The compaction of layers in a wet of optimum state is not expected to be an ideal alternative.
