"Soil Mechanics: Principles and Practice" by Graham Barnes

Whether you are a civil engineering student prepping for exams or a practicing engineer needing a reliable desk reference, remains one of the most respected texts in the field.

• Darcy’s Law: $v = ki$. Understand the limitations of Darcy's law (laminar flow).
• Coefficient of Permeability ($k$): Factors affecting $k$ (grain size, void ratio, fluid properties).
• Seepage Velocity vs. Discharge Velocity.
• Flow Nets: Constructing flow nets for dams and sheet piles. Calculating seepage quantity ($q$) and exit gradient ($i_exit$).

3. Fundamental Concepts

• Particle Size Analysis: Sieve analysis vs. Hydrometer analysis.
• Atterberg Limits: Liquid Limit (LL), Plastic Limit (PL), and Plasticity Index (PI).
• Classification Systems: How to use both the USCS (Unified Soil Classification System) and the AASHTO system. Tip: Memorize the plasticity chart.
