This example considers transient flow to a well in a confined aquifer for an axisymmetric model.

-
This file models a tempe cell or pressure plate cell test used to measure the volumetric water content function. It considers several drying stages and a re-wetting stage. It captures the matric suction phenomenon.

The objective of this example is to show how rapid drawdown of an embankment can be analyzed with SLOPE/W using the effective stress approach. The drawdown pore-water pressures of the embankment are modeled with a SEEP/W transient analysis. The stability of the embankment as a function of time is done by including "All" the SEEP/W time steps in the SLOPE/W analysis.

-
The objective of this illustration is to show how to model the rapid filling and drawdown of a reservoir. The boundary conditions are transient for both the filling and drawdown processes.
-
-
This advanced case study combines seepage results, stability analyses, dynamic analyses and post earthquake deformation. The dynamic model is an equivalent linear model.
-
-
This example compares SEEP/W results with a known solution for two infiltration cases. It models liners and caps and illustrates use of a unit gradient flow boundary condition. In addition, it will be shown that flow across a capillary break (whether a cap or pond liner) depends on the pressure profile established below the break location.

-
This example illustrates how to design and model a lysimeter. It considers two lysimeter sizes each under three different steady state flow infiltration rates.
-
-
This example models the preferential flow in a two-layered column with fine sand on one side and coarse sand on the other side. The results are used for verification of SEEP/W by comparing the results with lab measurements.
-
-
This example considers initial, transient and long term steady state infiltration through a lined pond. It looks at mounding of the water table and unsaturated flow. The zone below the liner remains unsaturated and the water table deep in the profile mounds due to percolation from the base of the pond.

-
This example shows how the Plan View option in SEEP/W can be used to investigate the spacing of pore-pressure relief wells along the downstream side of a long embankment for example.
-
-
The objective of this example is to show how the pore water pressure obtained from SEEP/W can be use directly in SLOPE/W. It also shows the seamless SEEP/W – SLOPE/W product integration in GeoStudio.
-
-
This example demonstrates the use of an uncoupled volume change analysis where the pore-pressures are computed with SEEP/W and the changes are used in a SIGMA/W volume change analysis.
-
-
In this example saturated tailings are deposited with an initial concentration of 1.0 into a basin. A new layer is deposited every 20 days. With each new layer, the contaminants from the previous state become the starting condition for the new stage.
-
-
This example studies seepage into a tunnel in soil when the tunnel is excavated under positive air pressure or just atmospheric air pressure.
-
-
This example illustrates the fresh water hydraulic heads calculated by SEEP/W for a coupled density-dependent groundwater flow problem.
-
-
This example demonstrates the use of surface regions in SEEP/W to consider infiltration, runoff and pond development in road ditches.
-
-
This example shows steady state infiltration into a layered soil strata and development of perched water tables and seepage faces.
-
-
The objective of this illustration is to observe how to use finite element pore-water pressure results in a stability analysis. Including or deliberately ignoring negative pore-water pressures can be critical to understanding and interpreting a slope stability analysis.
-
-
This steady state seepage example considers flow through a homogeneous dam for two cases: with or without a blanket drain at the toe.
-
-
This example considers air pressure build up beneath a wetting front under surface infiltration. It captures the matric suction phenomenon.
-
-
This example shows how air flows in response to heating or cooling. It couples air flow and heat flow and includes development of convection cells.

-
This example compares transient dissipation of excess pore-water pressure in a one dimensional consolidation test with no volume change.
-
-
This example shows infiltration through a pond liner using SEEP/W. Once the seepage is established, a particle tracking analysis is done followed by an advection dispersion analysis in CTRAN/W.
-
-
This example illustrates a convective heat transfer air flow cell in a closed box where one side is heated and one side is cooled. It couples seepage, air flow and heat flow.
-
-
One-dimensional infiltration into a dry soil column is modelled and the results are compared to the semi-analytical solution developed by Warrick et al. (1985).
-
-
This example illustrates two types of contaminant exit review boundary conditions: one in which dispersive flow is zero and one in which it is greater than zero.

Explores lab-measured anisotropy in field flow systems and demonstrates how to use the anisotropic feature in SEEP/W.
-
-
This example shows seepage into a tunnel with and without air pressure in the tunnel. It links air flow and water flow and considers the matric suction phenomenon.
-
-
The objective of this illustration is look at steady state flow under a cutoff when the soil exhibits anisotropic behavior.
-
-
This example shows how to consider the change in head in a pond due to seepage into or out of the pond. The head in the pond is not known and depends on the volume of water seeping out of the soil. It uses the Head versus Volume boundary condition.
-
-
This example considers 2D heat flow and simultaneous water flow with convective heat transfer in the water phase. It compares a conduction only analysis with one that includes convection heat transfer.
