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


Easy to Use

Defining a Seepage/Air flow Model
The unique CAD-like technology in SEEP/W allows you to generate your finite element mesh by drawing regions on the screen. You can then interactively apply boundary conditions and specify material properties. You can even estimate the material property functions from easily measured parameters like grain-size, saturated conductivity, saturated water content, and the air-entry value. If you make a mistake, you can correct it using the Undo command.

Viewing the Analysis Results
Once you have solved your seepage problem, SEEP/W offers many tools for viewing results. Generate contours or x-y plots of any computed parameter, such as head, pressure, gradient, velocity, and conductivity. Velocity vectors show flow direction and rate. Transient conditions can be shown as the changing water table position over time. Interactively query computed values by clicking on any node, Gauss region, or flux section. Then export results into other applications, such as Microsoft Excel or Word, for further analysis or to prepare presentations.


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
  • Plus many more!
