Groundwater (GW) is one of the most valuable natural resources and for that reason, the
GW protection and management is vital for human evolution, socio-economic development
and ecological diversity. During the last decades, the continuously increasing need of water
has led to a rapidly growing awareness in the field of GW management. At the same time
over exploitation and pollution of water resources are threatening the ecosystems. The
combination of these two problems which have acquired worldwide dimensions has forced
many scientists working in relative fields to search new, multidisciplinary approaches to
address them. Effective management and protection of groundwater resources require detail
knowledge and quantitative/qualitative characterization of aquifers. Thus, modeling and
planning of the GW through the use of modern technologies and approaches have become of
high priority towards this direction. This book provides leading-edge research on this field.
