Summary: Water repellency has a significant impact on soil water infiltration, but there is currently no suitable correlation model for water-repellent soils. To address this, the modified Green-Ampt model was validated, incorporating assumptions about the thickness of saturated and unsaturated zones and combining formulas for the suction head with the average saturated hydraulic conductivity. Three modified models (Green-Ampt-VG, Green-Ampt-BC, Green-Ampt-GP) were developed. Indoor water infiltration experiments were conducted to compare the performance of the models in simulating different treatments. The results showed that the modified Green-Ampt-VG model had the best simulation effect, closely matching the measured values with low root mean square error (RMSE) for infiltration rate and wetting front distance. These findings provide valuable insights for understanding water infiltration in water-repellent soils through the suction head values obtained from the VG model.

Summary: This study proposes a new infiltration model that considers the effects of ponding depth on infiltration, especially the formation of a saturated zone. The proposed model, called GAMS, shows better consistency with the numerical solution compared to traditional and improved models. The study also suggests a method for estimating soil hydraulic parameters based on the GAMS model. The results demonstrate that including the saturated zone in the infiltration model improves the estimation of soil hydraulic parameters.

Summary: This study proposes a modified GA model that takes into account the effects of roots and moisture redistribution on slope stability. The results show that increasing rainfall intensity and slope angle lead to a decrease in the wetting front depth and the safety factor of the slope. The shape of vegetation roots has a significant effect on reinforcing shallow soils.

Summary: This study conducted infiltration tests in loess deposits and proposed a quantitative calculation method for preferential infiltration. The results showed that the relationship between the infiltration rate of loess and the reciprocal of wetting front depth is linear under homogeneous infiltration but non-linear under preferential infiltration. The degree of preferential infiltration can be determined based on the distance of data points to the infiltration rate-wetting front propagation velocity gradient.

Summary: Predicting catchment stormflow responses after tropical deforestation remains difficult. The Spatially Variable Infiltration (SVI) model performs better than the Green-Ampt (GA) model in simulating observed streamflow responses to rainfall. The parameters of the SVI model are related to the moisture content in the top 10 cm of the soil prior to the rainfall event.

Summary: This study uses a comprehensive database of rainfall simulation experiments, state-of-the-art model parametrisation method, and linear mixed-effect models to analyze the relationship between soil and vegetation conditions and the model calibration parameter skinfactor. New empirically based transfer functions significantly improve the accuracy of the infiltration module in the EROSION-2D/3D model. Soil moisture and bulk density were found to be the most significant predictors of skinfactor variability, leading to a substantial improvement in prediction accuracy compared to the current method.

Summary: This study aimed to evaluate the performance of different infiltration models in estimating the infiltration rate under various soil and land use conditions. Field experiments were conducted using a double-ring infiltrometer instrument. Well-known infiltration models, such as Horton's, Philip's, Kostiakov's, and Green-Ampt, were developed based on field data. The models were evaluated using the R-2 value. The study found that Horton's model outperformed other models in predicting infiltration rate for forest, hard surface, and cultivated land, while Kostiakov's model was the best for barren land. Green-Ampt's model performed poorly under different conditions. These developed models will be useful for irrigation system design and hydrological modeling in the study area.

Summary: Soil water repellency, a phenomenon where soils resist water infiltration, has significant impacts on hydrology and geomorphology. This study introduces a time-dependent contact angle to develop a model for water infiltration into water-repellent soils, successfully verified through experiments with coated glass beads. Simulations show that infiltration rates in subcritical water-repellent soils with time-dependent contact angle can either increase over time or initially increase and then decrease.

Summary: It has been found that the infiltration of fluids into porous media often exhibits anomalous behavior, where the displacement of the fluid front varies with a different exponent v from the expected value of 1/2. Various transport models in fractal media predict these anomalies, but the associated exponents are non-universal, as they depend on fractal dimensions and other geometric properties. This study focuses on the infiltration in layered porous media with fractal distributions of lower conductivity inclusions, showing that superdiffusive infiltration with a universal exponent of v = 1/(1 + Df) can occur.

Summary: This study investigates the effects of erosion degradation and long-term manure fertilization on soil properties and crop yield in Northeast China. Results show that erosion degradation and manure fertilization have lasting impacts on soil physical structure throughout the soil profile, while their effects on soil nutrient properties are focused in shallow layers. Manure fertilization significantly improves soil functional index (ISI) and maize yield for degraded soils. Erosion degradation has a greater influence on ISI and maize yield than manure fertilization.

Summary: This study investigates the structural strength of the Loess-Paleosol Sequence (LPS) and finds that the strength tends to increase with burial depth, with the loess layer weaker than the paleosol layer. The microstructure of the LPS also undergoes significant transformations with increased burial depth, transitioning from an overhead structure to a matrix structure. These findings highlight the importance of climate conditions on the structural strength of the LPS.

Summary: This study aimed to evaluate the impact of long-term nutrient management practices on P fractions and P adsorption-desorption behaviour of an acid soil with a soybean-wheat cropping system. The findings revealed that amorphous Fe and Al, which play a significant role in P fixation, increased due to cultivation. The NPK+Lime treatment offered the most balanced approach, improving both crop yield and P uptake while effectively managing P dynamics in the soil. On the contrary, long-term application of NPK+FYM in an acid soil may result in faster P saturation of adsorption sites and increase the chances of leaching and eutrophication. Tailored P fertilization strategies should be developed to better utilize the PFe and PAl fractions and supplementing applied P.
