Lysimeters are used to determine the amount of deep infiltration into a Geo ¨C structure. Because most of the flow in a lysimeter is unsaturated, the design of a lysimeter is crucial to its long-term performance. It is very easy to design a lysimeter in which water enters a lysimeter but is pulled out through unsaturated capillary action prior to being drained from the lysimeter.
An unsaturated seepage numerical model such as SVFlux is ideal for the design of a lysimeter. In particular the mesh refinement in the unsaturated zone makes the software particularly well-suited for the calculation of unsaturated flow in an accurate way.
