Saturated soil is a research area that focuses on the study of soil properties and behavior when water content in the soil is at its maximum capacity. Saturated soil conditions occur when the soil pores are completely filled with water, leaving no room for air to penetrate. This can have important implications for various environmental and engineering applications, as saturated soil can lead to issues such as poor drainage, soil erosion, and reduced soil strength. Researchers in this area often investigate topics such as the hydraulic conductivity of saturated soil, the distribution of water in the soil profile, and the impact of saturation on soil compaction and stability. Overall, understanding the behavior of saturated soil is crucial for properly managing water resources, preventing landslides, and designing infrastructure projects.
