In this paper a preliminary study of the coastal aquifer of Eleftherae-N.
Greece, which suffers from seawater intrusion, is presented.
Flow inside the
aquifer is simulated by means of a numerical code combining boundary elements
and moving points.
A brief presentation of hydrological, geological and water
demand data is followed by an outline of the numerical simulation tool.
the simplifications of the actual flow field, introduced into the numerical model
and their impact on the accuracy of the results are discussed.
Two lower water
demand scenarios are also investigated.
Finally, some ideas to alleviate the local
seawater intrusion problem are discussed.

Sustainable development of coastal aquifers is a very challenging water
Excessive or poorly planned pumping results in seawater
intrusion, which, in turn, renders groundwater unusable.
The problem is already
acute in many areas of the world.
Population growth and the trend of
concentrating human activities in coastal areas increase the local fresh water
demand, for urban and agricultural use.
Meanwhile, water resources may tend to
reduce at the regional scale, due to unfavorable climatic change (reduction or
change of precipitation pattern).
Thus, a problem which first appeared in small
islands and low precipitation coasts affects already large coastal areas.
Management of coastal aquifers has, consequently, attracted the interest of
