*5. Geostatic Stresses:***Darcy’s law, hydraulic conductivity, pumping wells, flow nets, and seepage calculation.**

*6. Hydraulic Conductivity and Seepage:***Calculation of stresses due to point load, strip load, circular and rectangular area loads, Boussinesq theory, and influence charts.**

*7. External Stresses in Soils:***Mohr-Coulomb failure criteria, laboratory test for determination of shear strength parameters, triaxial test, and direct shear test.**

*8. Shear Strength of Soils:***Consolidation theory, OCR, void ratio-effective pressure plots, normally consolidated and over consolidated soils, compression index, swell index, secondary consolidation, and time effect.**
