Abstract

irrigational water demands of the farmers and the process water requirements of the industrial
establishments are most supplied from groundwater resources of the plain. This ever-increasing demands for
water could no longer be satisfied by the alluvial surfacial aquifer and, hence, numerous deep wells are being
drilled in the lower aquifers to supply these high demands. Based on the geological surveys performed in the
plain, three different rock formations are observed in the plain. The Mesozoic-aged Bornova Complex forms the
foundation of the study area. The Bornova Complex is composed of allochthonous limestone, sandstone, clayey
schist and phyllite. The consolidated Neogene sediment units overlay the basement rock by discordance. These
sedimentary units are composed of sandstone, claystone and limestone. Finally, as the youngest units of the
region, the Quaternary aged alluvial sediments overlay all other units. In accordance with this geological
structure, four different aquifers are determined in the plain. These are classified as: (i) Mesozoic-aged
allochthonous limestone in Bornova Complex, (ii) Neogene-aged sandstone and gravel, (iii) Neogene-aged
limestone; and, (iv) Quaternary-aged unconsolidated alluvial sediments. In this study, hydrogeological
characterization of Kemalpasa plain aquifers discussed above will be conducted and a three dimensional
interactive model of these layers is prepared. Finally, a three dimensional hydrogeological model of Kemalpasa
plain is prepared.
