Karst landscapes have two peculiar characteristics which make them immediately identifiable even where rocks are covered by soil and vegetation: particular forms of dissolution on the surface and the practically total absence of watercourses on the surface, as all the water or most of it, rapidly is swallowed into the depths. This characteristic makes the work of speleologists particularly important, because karst zones are generally characterized by water supply problems: the identification of underground water reserves, their localization and the study of the possibility of exploiting them are a very important contribution to the wellbeing of local populations, specially in the arid zones of developing countries.
