SVFlux - 2D Gallery - Earth Dam Problems

Dam Drawdown

The rapid drawdown of reservoir levels behind earth dams is a common cause of instability. SVFlux can be used to estimate the buildup of pore-water pressures in earth dams due to rapid drain-down. The resulting pore-water pressures may then be transferred to the slope stability package in order to calculate a factor of safety. It should be noted that automatic mesh refinement is important for solving these types of problems as significant refinement is often needed along the upstream face in order to accurately calculate gradients.

Complex Dam

This example shows the ability of SVFlux to solve extremely complicated problems with small regions. Large differences in hydraulic conductivity (up to 4 orders of magnitude) were placed adjacent to each other to illustrate the ability of SVFlux to solve problems typically impossible with other software packages.
