The percolation of water into soil can be modeled considering Darcy's Law in laminar flow. In this manner the key property is the coefficient of hydraulic conductivity. Its determination can be made through laboratory or field testing. One of the most known field tests used for determination of this property is the Slug Test. This test consists of a perforated well in the ground where a known volume of water is quickly added and then the water level is monitored over time until the recovery of the initial static level. Simulations done with COMSOL Multiphysics® software show that, for the simulated conditions, the water pressure stabilizes at 30000s and significant changes in the soil water pressure occur only at distances shorter than 1 meter from the center of the well.
