9. Effective stress under Hydrodynamic Conditions

The chapter discusses effective stress under hydrodynamic conditions, focusing on the effects of pore water pressure changes within soil due to seepage. It highlights how hydraulic gradients influence effective stress differently during upward and downward flows, emphasizing conditions like quicksand. The implications of changes in total stress and pore water pressure on soil stability, particularly under different water table conditions, are examined.
