Abstract:

The aim of this paper is to study the historical alluviation of Thessaloniki
using mainly archaeological data. Such data have been found in many places in
the study-area. These findings date from the Neolithic to the Ottoman period.
We have approached this problem by studying the geomorphological processes
of this area and through detailed mapping of the alluviation around ancient
monuments.
A spatial database was created containing geological, geomorphological and
archaeological data, along with all measurements collected during fieldwork.
Apart from contemporary data, older topographical maps of the area were also
imported and analyzed in the GIS together with the other datasets. The results
indicate that deposition rates vary on temporal and spatial scales. This is due to
the topography, the lithology and the climatic changes in the area. Thus, the
whole landscape of Thessaloniki area has undergone continuous change; we
have estimated vertical deposition rates ranging between 1,66 and 7,5 mm p.a.
