TLDR
In this paper, the hydraulic conductivity in gravelly soils containing various contents of gravel particle fraction under cyclic freezing-thawing was investigated, and the results showed that hydraulic conductivities significantly depend on gravel content, confining stress, number of F-T cycles and initial water content.About:

Strength and post-freeze-thaw behavior of a marl soil modified by lignosulfonate and polypropylene fiber: An environmentally friendly approach
TL;DR: In this paper , an environmentally friendly strategy involving lignosulfonate as a binder along with the polypropylene (PP) fiber as a reinforcing material was adopted to enhance the characteristics of marl soils from detrimental impacts of freeze-thaw (F-T) cycles.

Response mechanism of permeability change of remolded loess to seepage parameters
TL;DR: In this article , the authors explore the response mechanism of permeability change of remolded loess to temperature, hydraulic gradient, and initial moisture content, and find that the saturated hydraulic conductivity (Ksat) increases with seepage time at 10 and 20 ℃, while it decreases at 30 and 30 µm, respectively, due to the comprehensive effect of temperature on the fluid viscosity, bound water film, and chemical leaching.

Effects of Spatial Variability of Saturated Hydraulic Conductivity on Hortonian Overland Flow
TL;DR: In this paper, the kinematic wave equations with interactive Smith-Parlange infiltration are solved by a finite-difference scheme on a characteristic computational net, and it is shown that runoff hydrographs are strongly affected by trends in hydraulic conductivity, particularly for small runoff events.
