Summary

Messara valley is the largest and most productive agricultural region on the island of Crete. The farmland irrigation needs, and the lack of environmental awareness led to groundwater extensive exploitation and substantial drawdown of piezometric surface. This thesis aims to evaluate ground subsidence resulting from groundwater overexploitation in the area of Vagionia - Asimi. Land subsidence mechanism was analyzed, and the kinematic behavior of the formations was simulated by finite element software. The expected land deformations were evaluated in relation to the aquifer exploitation and the results were compared with land subsidence estimated by other investigation methods.
