The main objective of this work is to determine the parameters of
hydrological balance for several basins in the prefecture of Korinthia (SE
Greece), using hydrometeorological data and geographic information systems
(GIS) technology. Multiple linear regression and GIS were used to estimate
the spatial distribution of rainfall. The largest precipitation amounts
occur in the SW part of the region and decrease towards the eastern and
northern coastal parts. The long term mean annual rainfall is
1.39×10<sup>9</sup> m<sup>3</sup>. Based on the Thornthwaite method, infiltration and streamflow were
estimated to be 0.29×10<sup>9</sup> m<sup>3</sup>/yr and 0.38×10<sup>9</sup> m<sup>3</sup>/yr,
respectively. The unequal distribution of rainfall results in water surplus
in the western part of Korinthia prefecture and water deficit in the
eastern. We conclude that he estimation of hydrologic balance is a useful
tool in order to establish sustainable water resources management in each
hydrological basin.
