| Zusammenfassung |
| Sinkhole development occurs in many areas of the world where soluble rocks
crop out. Sinkholes are generally the surface expression of the presence of
caves and other groundwater flow conduits in carbonate rocks, which are
solutionally enlarged secondary permeability features. Their formation may
be either natural or caused by man's activities. In both cases, heavy
consequences have to be registered on the anthropogenic environment and
related infrastructures. Knowledge of the mechanism of formation of this
subtle geohazard is therefore necessary to planners and decision makers for
performing the most appropriate and suitable programs of land use and
development.
The Apulia region of southern Italy is characterized for most of its
extension by carbonate rocks, which makes it one of the most remarkable
example of karst in the Mediterranean Basin. Based on analysis of literature
and in situ surveys, including caving explorations, we have identified in
Apulia three main types of possible mechanisms for sinkhole formation: 1)
collapse of a chamber in a natural cave or in man-made cavities; 2) slow and
gradual enlargement of doline through dissolution; 3) settlement and
internal erosion of filling deposits of pre-existing dolines. Since sinkhole
formation very often affects directly the human settlements in Apulia, and
have recently produced severe damage, some considerations are eventually
presented as regards the interrelationships between sinkholes and the
anthropogenic environment. |
