Sample SEEP2D Problem
SEEP2D can be used for either confined or unconfined steady-state flow models. For unconfined models, there are two options for determining the phreatic
surface. With the first option, the mesh is automatically truncated as the iterative solution process proceeds and when the model converges, the upper boundary of the mesh corresponds to the phreatic surface. With the second
option, both saturated and unsaturated flow is simulated and the mesh is not modified. The phreatic surface can be displayed by plotting the contour line at where pressure head equals zero.
A variety of options are provided in GMS for displaying SEEP2D results. Contours of total head (equipotential lines) and flow vectors can be plotted. An option
is also available for computing flow potential values at the nodes. These values can be used to plot flow lines. Together with the equipotential lines (lines of constant total head), the flow lines can be used to plot a flow
net.
A more complete description of the SEEP2D model, including a discussion of boundary conditions and guidelines for model conceptualization is contained in the
SEEP2D Primer. The SEEP2D Primer should be reviewed before consulting this help file. The user is also encouraged to complete the SEEP2D tutorials in the GMS Tutorials document.
