Comprehensive and Powerful

SEEP/W is a finite element software product for analyzing groundwater seepage and excess pore-water pressure dissipation problems within porous materials such as soil and rock. Its comprehensive formulation allows you to consider analyses ranging from simple, saturated steady-state problems to sophisticated, saturated-unsaturated time-dependent problems. You can apply SEEP/W to the analysis and design of geotechnical, civil, hydrogeological, and mining engineering projects.

 

Saturated / Unsaturated Flow

SEEP/W can model both saturated and unsaturated flow, a feature that greatly broadens the range of problems that can be analyzed. In addition to traditional steady-state saturated flow analysis, the saturated/unsaturated formulation of SEEP/W makes it possible to analyze seepage as a function of time and to consider such processes as the infiltration of precipitation. The transient feature allows you to analyze such problems as the migration of a wetting front and the dissipation of excess pore-water pressure.

 

Typical Applications

SEEP/W can model almost any groundwater problem including:
  • Dissipation of excess pore pressure after reservoir drawdown
  • Changes in pore-water pressure conditions within earth slopes due to infiltration of precipitation
  • Mounding of the groundwater table beneath water retention structures such as lagoons and tailings ponds
  • Effect of subsurface drains and injection wells
  • Drawdown of a water table due to pumping from an aquifer
  • Seepage flow quantities into excavations
  • Use AIR/W and consider the true matric suction (Ua-Uw) mechanisms
  • Integrate with TEMP/W and consider flow in freezing and thawing soils

Formulation

Soil Properties The hydraulic conductivity of the soil is a function of the negative pore-water pressure in the unsaturated regions. The rate of change in water content is dependent on the pore-water pressure during transient processes. Hydraulic conductivity can be defined as anisotropic in two orthogonal directions.
Iterative Process The nonlinear nature of the finite element equations is handled using an efficient radial search iterative scheme.
