The infiltration of water from small cavities filled with water is affected by gravity, both within and without the cavity and these two effects are of the same order. The effect within the cavity is assessed quantitatively for small spherical cavities that are entirely or partially buried in the soil. As an example, the case of a cavity entirely buried in the soil is discussed in detail.
