Objectives of PP6:
 Contribution to the reconstruction of the hydrological cycle in the CADSES
Region on a GIS frame and estimation of water budgets.
Analysis of the water resources management of the Ionia Islands under
extreme situations (flood and drought events)
 Identification of the appropriate methodologies for the awareness
and the Management of Natural risks
 Training courses for technical personnel
 Installation and operation of the Telemetric hydro-meteorological stations
and the monitor of extreme events in real time.
 Contribute to the development of a common and homogeneous data – base
for the CADSES area
 Planning of possible extensions of the project to other European areas

Kefalonia Island
The island of Kefalonia belongs
to the Ionian Islands
The Ionian Islands have the
privilege of having a great
quantity of hydrological entries

The current hydrological condition of the island of Kefalonia is
critical. It is the driving force for the selection of this Ionian island
and the realisation of a hydrological investigation.
Purpose:
Analysis of the water
resources management of
Kefalonia island and the
recommendation
of
a
proper
approach
and
solutions

 Kefalonia is the largest of the Ionian islands,
 The total area of the island is 808 Km2
 Geographically the island is split into two districts, the east which is
intensely mountainous and the much smaller west which is mainly hilly
 Its mountainous highland surpasses all of the other Ionian islands with
ranges that begin at Cape Dafnoudi and end at the most south point at Cape
Mounda
 The maximum elevation is 1628 m
 The coasts of Kefalonia form many bays and land masses
 Of particular interest are the caves of the island, for example the precipitous
Melissani, Agalaki, Saint Theodoron, Zervati, Drogarati, Sakou, etc
 The climate of Kefalonia is Mediterranean with high relative humidity and
great annual and monthly precipitation
 The mean annual precipitation of Kefalonia is 1000 mm

 Geological substance consists of calcareous formations
 In the calcareous rock are generated aquifers, which are victual from the rich
precipitations
 The main feature is the karst phenomenon, which determines the condition
of the aquifers in the island
 Many hydrogeological units
of the island are open, from one
or more sites, to the sea, with
which are in free hydraulic
contact for many kilometres
 The sea water penetrates in
the internal of the island in great
distance
 In many cases fresh water is
polluted by salty water

 The implementation of new techniques and methodologies in
hydrology and the optimum water resources management are based
on the installation of reliable systems to record and process the
hydrometeorological information
 The importance of such networks is enforced by the Water
Framework Directive’s provisions that require the installation of
representative monitoring networks of all the parameters of the
hydrological cycle
 Hydrometeorological monitoring networks can contribute
significantly in the monitoring of extreme events in real time as well
as in the mapping of climatic and bioclimatic conditions
Measuring variables: Precipitation, Temperature, Humidity, Wind
(speed, direction, gust), Radiation (solar, total) and Sunshine
duration

The stations are placed on
land with even slopes, far
from trees or buildings and
relieved
from
local
atmospherical turbulences
For the investigation of
events in a local scale,
each station must cover an
area of 10 km2 at maximum
