The role of physiochemical properties of soils and eroding fluids in soil erodibility: a critical review

Soil erosion, a process of removing earth materials such as soils or rocks by flows and/or waves, poses significant threats to the environment, infrastructure, and economy. The erodibility of soil is profoundly influenced by the physiochemical properties of both soil and eroding fluids; however, these effects are not yet fully understood. Therefore, it is essential to establish a clear relationship between these physiochemical factors and soil erodibility. Significant progress has been made over the past few decades in understanding how factors like temperature, pH, and salt concentration affect soil erosion behavior. Despite this progress, the results often remain inconsistent and difficult to apply in practice due to variations in research methodologies and incomplete understanding of erosion mechanisms. This paper reviews and synthesizes existing research on the physiochemical effects of soils and fluids on the erodibility of different soil types, providing a comprehensive overview of the relative and interactive influences of these factors. Additionally, recent advancements in understanding soil erosion mechanisms are discussed.
