Unsaturated soil refers to soil that contains both air and water in its pores, with the water content being less than its saturation level. This condition significantly influences the soil's mechanical and hydraulic properties, impacting its stability and behavior in various engineering and environmental contexts.

Unsaturated Soil

Soil Mechanics is the branch of civil engineering that studies the behavior of soil under various conditions, which is crucial for designing safe and effective foundations, retaining structures, and earthworks. It involves understanding the properties of soil, such as its shear strength, compressibility, and permeability, to predict how it will react to loads and environmental changes.

Soil Mechanics

Hydraulic properties refer to the characteristics of a material or system that define its ability to transport fluids, typically water, through its porous structure. These properties are crucial for understanding and predicting the movement of water in natural and engineered systems, such as soil, aquifers, and pipelines.

Hydraulic Properties

Soil stability refers to the ability of soil to maintain its structure and resist erosion, compaction, and degradation under varying environmental conditions. It is crucial for supporting plant growth, preventing landslides, and maintaining water quality by reducing sediment runoff.

Soil Stability

Soil behavior refers to the response of soil to various physical and chemical processes, including stress, strain, and environmental changes. Understanding soil behavior is crucial for applications in geotechnical engineering, agriculture, and environmental management as it influences soil stability, fertility, and permeability.
