Abstract:

The aim at this paper is to study the historical allouviation of the area of
Thessaloniki using mainly archeological data. Such data has been found in many
places in this area. These findings (buildings, castles, road traces, fortifications) date
back from Neolithic up to Ottoman period. We have approached this problem by
studying the geomorphologic processes of this area and by mapping in detail the
allouviation of the ancient monuments. A spatial database has been created attributing geological, geomorphological, hydrological, other environmental and archaeological data along with all the measurements undertaken during fieldwork. Apart from contemporary data, older topographical maps of the area have also been input and analysed in the GIS together with the rest datasets. A specific methodology was applied in view of recording and studying the erosion-deposition rates. The derivative results have indicated that deposition rates vary within diverse temporal and spatial conditions. This is due to the topography, the lithology and the climate changes of this area. The study, also, reported that in some places vertical depositions rates at about 0, 5 cm/year. The applied model tracing erosional processes and deposition rates can be implemented in any other location irrespective of the environmental, spatial, or archaeological data characterizing the area.
