Original Title:
Υδρογεωλογική έρευνα στην περιοχή εδαφικών διαρρήξεων Κάρλας Ανατολικής Θεσσαλίας
Summary:
This thesis investigates the hydrogeological and hydrochemical conditions that
prevail in Karla plain Eastern Thessaly, where ground fissures phenomena
occurring since 1989, resulting in damages to buildings, roads, railways,
cultivations. In accordance with existing geophysical and drilling data
(Sogreah Grenoble, 1974 etc.) Karla plain is mostly covered by Quaternary
sediments of lacustrine and fluvial origin and her bedrock consists of alpine
formations that geotectonically belong to Almopia unit and tectonic nappe of
ophiolitic of Axios. In the southwest margins of the study area are identified
Upper Cretaceous transgressive sediments. The main interest in terms of
groundwater resources in the study area focuses on the alluvial and karstic
aquifers. Processing of data concerning the piezometric data (that received
from the Department of Water region of Thessaly, for the period 1973 – 2009),
indicates a continuous systematic lowering of the underground tables from
aquifers formed in alluvial deposits. As regards the groundwater quality, the
main pollutants identified are the nitrates due to nitrogen fertilizers,
chlorides and the sodium ions. The increasing abstractions of groundwater (over
pumping) for irrigation purposes led to pronounced groundwater overexploitation
and thus created the appropriate conditions for causing subsidence - ground
fissures.
