Water is a natural resource and is the base of life in our planet.
In the last years the awareness that water is a limited resource has became a reality also in
area where it is abundant.
The indiscriminate use of water, the poor protection of the groundwater and of the recharge
areas represent a important menace for its availability and use for the next generations.

European Union has always demonstrated a great sensibility for
environmental topics and in particular for those related to water cycle.
These ones are well represented in the goals of the LIFE programme as expressed
in the promotion of the concept of
sustainable exploitation of surface
and underground water.
In this framework Institutions,
research Centres public and private
operators and all the actors involved
in the environmental sectors inside
the EU and abroad are requested to
have a strong professional role .
On this base the realisation of one the
most important directive for the protection
of the water resource has been
proposed and obtained.
The CAMI Project
The CAMI Project (Water-bearing characterization with integrated methodologies)
has been co-financed by the EU in the frame of the LIFE programme.
It contributes to the enforcement of the EU directive 2000/60/CE and further modifications
by developing and testing an integrated method aimed at the definition
and characterization of the hydro geological districts,
the analysis of the environmental impact of human
activities on the water resource and to the evaluation of
sustainability.
The water directive 2000/60/CE introduce in the EU legislation
the innovative concept of the management of water
resources based on hydro geological basins instead on
administrative limits and districts.
The CAMI Project permitted to develop an integrated
approach based on geophysical, geochemical and monitoring
activities covering a whole hydro geological basin and
applied in the test area of Torrate di Chions ( PN-Italy).
Piezometric tower – ABL (Torrate di Chions).
Hydrogeological distric and test area
Hydrographic basin of Tagliamento river. Location of the study area.
One of the main components of the CAMI project
is the experimental activity.
It is based on a series of investigation campaigns
in the territory of the pedmontain area belonging
to the Veneto Region and the Friuli Venetia Giulia
Region between the Meduna-cellina and
Tagliamento rivers.
The area is characterised by high permeability
alluvial fans hosting one of the most important
aquifers of the two regions.
The intensive agriculture, the industrial settlements
and the high urbanisation determine the
high vulnerability of this aquifer.
Actions
The filed surveys and the geochemical analyses
and the geophysical investigations permitted to:
determine the feeding reservoirs and their interactions
by the study of isotopic analysis of
O18 and Tritium Activity on samples collected
from underground and surface waters, rainfall
and snow;
Precisely understand the subsoil by the 3D
reconstruction of the system of exploited aquifers
and the characterization of the typical
petrophysical, hydraulic and hydrochemical
parameters;
To determine the hydrodynamic characteristics
of the aquifer during exploitation.
Area test.
Project set-up
The project is organised in a series of tasks and actions developed
acconrding to the following scheme:
Gathering and organisation of available data;
Stratigraphycal analysis, construction of preliminary geological
model and design of geophysical investigations;
Realization of the geochemical and isotopic data collection;
Realization of geophysical surveys;
Interpretaion of geophysical data and integration of the hydrogeological
model;
Hydrogeological interpretation and modelling of the aquifer;
Realization of thematical maps, maps of recharge/dispersion areas,
vulnerabiliy, etc.;
Modelling of aquifer by REGIS software;
Construction of a model of the spring barrier system and development
of a protocol for the characyterization of hydrogeological
basins as (Dir, 2000/60/CE);
Dissemination of results by web site( state of advancement of the
research, intermediate results, final results) conferences, seminars
and multimedia material.
Seismic survey in the study area.
Final goal of the project
The goal of the project is the determination of a investigation and monitoring
protocol to guarantee homogenous results in different hydrogeological
settings as specially required by the EU directive.
