Abstract

[automatically translated] The Disueri tank on F. Gela was created with a masonry dam dry, completed in 1948, replaced in 1997 with an earthen dam. Both dams are built on rocks of Chalky-Solfifera series that in the barrier area is affected by folds and faults that give rise to a highly complex structural setting. On the left bank emerges a selenitic chalks bench affected by numerous cavities, several of which large. The evolution of the cavities is rapid because of the high dissolution rate of the plaster casts in flowing water conditions, and has given rise to a large basin subsidence and displacements that leave envisage the formation of a real waterbank breaking mechanism .
