Abstract
Erosion is the process of eroding the surface of the topsoil caused by the intensity of the rainfall that occurs and causing splashes due to the working kinetic energy (J/m2), coupled with runoff due to the slope factor, which is influenced by soil type and land cover. The characteristics of soil type and topography cause damage to the topsoil and push the sedimentation volume to increase from time to time. Therefore, Road safety infrastructure buildings, such as cliff protection on a slope, irrigation building walls, and so on, require good security to avoid collapse or loss of slope stability. Reducing the occurrence of kinetic energy in the topsoil surface layer and reducing erosion can be done by making a surface layer with a porous concrete pavement structure. However, first, it is necessary to analyze the amount of kinetic energy acting on the soil surface. The positive effects of porous concrete layers on slope stability are discussed using: i) geo-mechanical effects, namely soil reinforcement with shaft concrete; ii) soil hydrological effects, namely the suction regime of the soil, which is influenced by the absorption of water flowing through the concrete shaft; iii) the effect of using artificial aggregate as a sustainable material in porous concrete. A one-dimensional vertical groundwater dynamics model is assumed to simulate the soil suction regime, representing soil covered with shaft concrete on slopes with various gradients. It was found that in various soil types and different slopes, in the case of sandy loam soils, geo-mechanical effects tend to be more relevant than soil hydrological effects during the rainy season.
