Comprehensive flowchart mapping mechanical and hydraulic soil properties from definition through geotechnical failures, structured for UTMACH Civil Engineering curriculum. The diagram traces soil classification from origin (residual, transported, organic) through index properties (texture, particle shape, color, structure) and historical development via pioneers like Terzaghi, Coulomb, and Darcy. It connects theoretical foundations to real-world geotechnical failures including differential settlement, foundation collapse, liquefaction, and slope instability. Students and practitioners can fork this diagram to customize for regional soil types, add site-specific case studies, or integrate into geotechnical reports and educational materials. This structured approach ensures comprehensive understanding of soil behavior before advanced analysis and design work.
