Biochar has emerged as a promising soil amendment to improve structure. Yet, its impact on rainfall-induced erosion varies across individual studies. To address this gap, we conducted statistical meta-analysis of 174 paired comparisons from 45 published studies integratedly evaluate the impacts biochar through and properties, well experimental conditions. Overall, significantly reduced by 27.86%. The response ratio (lnRR) biochar-induced exhibited significant variability different subgroups. Concerning more favorable influence was observed in others (e.g., manure sewage sludge biochar) compared wood based crop waste biochar, those produced at lower pyrolysis temperatures (< 500°C). Increasing dosage is not consistently effective. optimal range 0.8-2%, resulting 36.07% reduction erosion. Regarding higher sand/clay enhanced performance (p < 0.0001). Specifically, an insignificant effect fine-grained soils, whereas highest 52.97% noted coarse-grained soils. Moreover, long-term field experiments induced greater reductions with (35.30%) short-term laboratory (29.62% 12.59%). This demonstrates that potential amendment, could effectively mitigate considering combination properties along specific properties.

An Analytical Insight Into Stability Analysis of Unsaturated Multi‐Layered Slopes Subjected to Rainfall Infiltration

International Journal for Numerical and Analytical Methods in Geomechanics, Год журнала: 2024, Номер 48(17), С. 4291 - 4303

ABSTRACT Slopes in nature usually present layered characteristics, and its stability is susceptible to rainfall events. Considering that current analytical solutions are only suited simulate the infiltration of double‐layered infinite unsaturated slopes, an procedure hence proposed this study tackle consideration multiple layers. The variable separation method transfer matrix combined derive solution pore water pressure (PWP) for simulating slopes. After having validated model by comparing with existing literature numerical simulation, closed‐form PWP incorporated into limit equilibrium assessing slope stability. A three‐layer selected as example further discussion. distribution factor safety calculated, considering effects saturated hydraulic conductivity thickness upper layer, intensity antecedent subsequent rainfall, varied soil unit weight along depth. subjected consistent variation PWP. provide a simple practical avenue computing evaluating multi‐layered slopes under conditions, which can also serve benchmark solutions.
