  • Water content in unsaturated soil and porosity are required to estimate the flow rates
Semi-Coupled Analysis
  1. Seepage force resulted from the groundwater flow generates displacements and stresses in the ground
  1. Calculate seepage forces using the pore water pressure obtained from seepage analysis
  1. Seepage force is centralized around the outflow boundaries where the total head decreases drastically
  1. Relatively low confined pressure near the outflow causes a decrease of shear and tensile strengths of the soil
  1. This effect can be considered in conjunction with stress analysis in construction stage analysis
Consolidation Analysis
