Summary:
The objective of this research is to design an integrated model to simulate the
groundwater flow in heterogeneous fractured media, in order to study the
hydraulic conditions and the aquifers that are developed in hard fractured
rocks. Specifically, all the factors affecting the groundwater flow in hard
fractured rocks are studied, such as the geology, the geomorphology, the
characteristics of the fracture pattern, etc. (internal factors),
simultaneously with the study of the climatic factors and the landuses
(external factors). Also, a prediction of the changes in the groundwater
systems by the year 2100 has been made, by studying the future climatic
conditions due to the climate change in Greece. Finally, an estimation of the
hydraulic parameters by using a multi-criteria analysis and the analytic
hierarchy process to simulate the groundwater flow has been made. As a result,
a three-dimensional representation has been created, by using the finite
element method and the software packages SWAT and WASY FEFLOW.
The design of the model and the simulation of the groundwater flow is applied
in the island of Naxos, which is consisted mainly by hard rocks. The designed
model can be used in the rest of the Cyclades Islands, which is referred from
now on as the "Cycladic Hydrogeological Model".
