This present dissertation examines the description, analysis and interpretation
of hydrogeological and hydrochemical conditions prevailing in the deltaic area
of Volinaios river, in order to identify areas more or less sensitive to
contaminants.
The assessment and vulnerability mapping of groundwater resources of the study
area were accomplished using the DRASTIC and the AVI computer models. These
methods based on evaluation of various hydrogeological, hydraulic and soil
parameters in relation to their capacity to influence the flow of contaminants
in the groundwater system.
By applying the DRASTIC method, a vulnerability mapping was created by
overlapping the individual criteria with their respective weights. By applying
the AVI method the factor of hydraulic resistance (c) was calculated, according
to which constructed the map of AVI index.
To compare these methods three common values of risk were defined: low, medium,
high. Based on common calibration two new maps were created for each method. A
good correlation of 69% between them was calculated. This is mainly due to the
parameters taken into account both.
Finally, correlation between the DRASTIC and the AVI index maps and the Nitrate
concentration were calculated. The correlation coefficient is 51% for the
DRASTIC method and 83% for the AVI method.
