Summary: The study developed a new hydraulic conductivity model for frozen soils based on the Kozeny-Carman equation, which can be used to explain the migration of water and heat in frozen soils compared to unfrozen soils. Parametric analysis revealed that unfrozen water saturation and shape coefficient ratio are important parameters affecting hydraulic conductivity. The proposed model can also be simplified to a power function for easy use.

Summary: Grouping soils based on similarities in their textural, taxonomic, and/or structural properties has broad applications to pedology, hydrology, and soil science. In this study, a new approach for classifying soils using hydraulic conductivity data was presented, and eight different soil classes were identified within the studied data set by calculating critical pore sizes and grouping soils with similar characteristics.

Summary: Research indicates that rock fragments influence the bulk density, porosity, and soil chemistry of fine earth, and have water retention capabilities. Rock fragments in the size range of 2-20 mm retain more water, and at a depth of 60 cm, they account for approximately 10% of water retention at field capacity.

Summary: The soil freezing characteristic curve (SFCC) describes the relationship between soil temperature and unfrozen water content during freezing and thawing processes. This study determined the SFCC of sandy soils in a laboratory setting. The results showed that the SFCC was influenced by the fines content, with higher fines content resulting in a lower temperature of spontaneous nucleation and a higher residual unfrozen water content.

Summary: This study introduces a novel method to predict hydraulic conductivity curves (HCCs) fully from the soil water retention curve (SWRC) without requiring additional parameters. Testing with soil samples shows that this method significantly improves the prediction of HCC compared to traditional methods.

Summary: Understanding the effect of sample volume on soil properties is important for hydrogeology, soil physics, and environmental engineering. This study uses percolation theory to estimate the scale dependency of hydraulic conductivity in soils. The researchers applied classification methods and conducted experiments on soil samples from four Danish sites to determine the relationship between pore size distribution and hydraulic conductivity. The theoretical estimates aligned well with experimental measurements, showing that the theory provides accurate estimations in certain soil textures and classes.

Summary: Microplastic pollution in the soil has detrimental effects on soil structure and water-holding capacity, impacting the soil water characteristic curve (SWCC). This study investigated the influence of different concentrations and sizes of polyethylene microplastics (PE-MPs) on SWCCs in sandy and loamy soils. Results showed that low concentrations of PE-MPs had minimal effects on soil water content, while high concentrations significantly affected water-holding properties, with smaller MPs enhancing water retention in loamy soil and larger MPs reducing water content in sandy soil.

Summary: We investigated the physical and hydric attributes of an Oxisol in northwestern Parana state, Brazil and found that crop cultivation on sandy soils is vulnerable to water stress. By analyzing soil samples and measuring various soil properties, we discovered that an increase in coarse sand content improves soil permeability and water storage capacity, while an increase in fine sand content reduces permeability but increases soil moisture content in subsurface layers.

Summary: This study develops a simple water retention model for dual-porosity soils that considers the self-similar characteristics of the pore size distribution (PSD) between macropore and micropore regions. The model simulates the macropore PSD using the differential VG model, which is then shifted and scaled to capture the micropore PSD. The results show that the proposed model can accurately predict the water retention behavior and hydraulic conductivity of dual-porosity soils.

Summary: A new modification to the van Genuchten soil water retention model is proposed, aiming to improve the agreement between predicted and measured relative hydraulic conductivity by combining with the Mualem model. The modified model, MVG-BCB, shows significant improvement in predicting relative hydraulic conductivity for soils with varied textures, eliminating sharp drops near saturation.

Summary: This study aims to predict the thermal conductivity of freezing soils. By analyzing different SFCC estimation models and quartz content estimation models, an estimated SFCC-based geometric mean model was proposed, considering the ease of obtaining soil parameters. The results showed that the Xin et al. SFCC model performed the best in estimating thermal conductivity.

Summary: The study found that using a generalized porosity constant in dielectric techniques can introduce additional structural bias in calibration, while using variable porosities can reduce this bias. Only the CRIMP model with a perfect model structure can effectively cope with porosity variations and maintain stable calibration capability.
