An unconfined aquifer (L1=15m, k 1=1x10-3 cm/s) lies above a confined aquifer(L2=10m, k 2=5x10 -5 cm/s). The two aquifers are separated by a clay layer (Lc=0.5m). A well is placedinto the confined aquifer, and it is observed that the water rises to a height of h = 0.75m above the watersurface in the unconfined aquifer.
