“…The results of the in situ soil (C-90-0-10) rainfall test showed a clear soil loss in the form of scour immediately after the start of rainfall. Over time, the degree of scour became increasingly severe, and after 15 min, rainwater infiltrated the soil and caused the surface to slide, resulting in failure [2,13].…”

Due to the impact of climate change, extreme rainfall events are becoming more frequent, resulting in shallow slope collapse and erosion that trigger debris flows. While traditional reinforcement methods like anchoring and nailing are effective, they can be costly and environmentally unfriendly. To address this issue, researchers have investigated using in situ soil reinforcement with vegetation, which is a more sustainable and economical option. In this study, a soil improvement agent was developed using leaf mold and herbal medicine to promote vegetation growth. Adding microcement and gypsum hemihydrate increased the shear strength of the soil, preventing surface erosion. A laboratory test confirmed that the combination of these ingredients effectively increased the soil’s resistance to erosion caused by rainfall. The soil improvement agent proposed in this study was applied to the case of the slope failure in the Gwangju area, South Korea, to confirm the slope stability for 10 days of rainfall. The results of numerical analysis confirmed that the reinforced slope cured by the pozzolanic reaction using the developed material improved the slope stability by 36% compared to the original soil slope during the rainy season.

“…Microflows occur at a certain critical distance downstream on the slope and continue in parallel for a certain length before merging with larger seeps. Thus, surface runoff detaches soil particles that have been detached by precipitation and transports them downstream, where they settle [52].…”

Determining the Anti-Erosion Efficiency of Forest Stands Installed on Degraded Land

et al. 2022

Erosion caused by human activities is one of the reasons for forest soil degradation worldwide, with a direct impact on forest stands development, including reduced forest productivity. Therefore, in order to establish sustainable stand management practices, it is essential to assess soil losses in various forestry activities. Moreover, this phenomenon is studied little in stands, especially those established on degraded land. In Romanian geographical conditions, where sloping land is up to 67% of the territory and is influenced by natural factors as well as intense human activities, the soil and vegetation suffer serious ecological imbalances. In order to achieve the proposed objectives regarding the evaluation of stands in terms of anti-erosion effectiveness, we analyzed the consistency and the number of trees on the surface, the weight of the seedlings, and the surface runoff from the perspectives of rainfall and soil retention. In the two stands included in this study, the influence of rain intensity was 39% in compartment 49 and 38% in compartment 73, directly influencing surface runoff. The ground retention’s influence on surface runoff was 28% in both compartments. The indirect surface runoff was influenced by the consistency of the stands and by the degree of proximity of the crowns, which directly influenced the intensity of rain. In addition to analyzing these two parameters (rain intensity and ground retention), it was also observed that the degree of proximity to the crowns directly influenced the intensity of the rainfall within the forest, which, in turn, indirectly affected the runoff.
