TLDR
In this article, the authors investigated the effect of initial hydraulic response during the initial stage of wetting in compacted clay liners and found that the cracks in liners act as preferential flow paths and affect the hydraulic response.Abstract:

Study on Crack Development in Red Clay from Guangxi Guilin with Different Clay Grain Content
Bo Liu,Liang Wang,Bai Yang +2 more
TL;DR: In order to study the influence of different clay contents on the fractality of red clay, specimens having four different water contents were prepared as discussed by the authors , and the cracking characteristics of the specimens were observed at 20 °C and 60 °C. Image J software was used to measure and calculate the crack area, crack ratio, crack length and width of each sample.

Analysis of Hydraulic Gradient Effects for Laboratory Hydraulic Conductivity Testing
TL;DR: In this article, a theoretical model was presented that characterizes the effect of hydraulic gradient on measured hydraulic conductivity in the laboratory, and the authors concluded that excessive hydraulic gradients applied during hydraulic conductivities testing can cause reductions in measured conductivity.

Determination of volumetric shrinkage of an expansive soil using digital camera images
M. Julina,T. Thyagaraj +1 more
TL;DR: The volume change during drying of compacted expansive soils occurs in the form of reduction in overall volume and development of cracks as discussed by the authors, and accurate determination of volume of shrunken soil specimens can be found in the literature.

Effects of specimen consolidation on the laboratory hydraulic conductivity measurement
Jayantha Kodikara,Fashiur Rahman +1 more
TL;DR: In this article, laboratory hydraulic conductivity tests are used for the design of clayey liners in waste containment, although relatively small hydraulic gradients are encountered under field conditions, and the results show that they can be used to evaluate the performance of such liners.
