Paper Abstract

The objective of this study was to process and integrate Landsat-TM images along with aerial photography, for the identification of water outflows in the coastal area of south Attiki peninsula. Digital image processing of Landsat data facilitated the identification of water outflows. Thermal anomalies have been detected by visual interpretation in the coastal areas. Air-photographs interpreted to map linear features and analyze the tectonic structure. A DEM along with field geological data used to verify the results and model the information. Water outflow patterns along coastal areas can be seen or inferred from the satellite images. Thermal anomalies due to water outflows have been identified on the FCC of thermal - with mid - infrared bands. These coincide with areas where fresh water outflows or liquid pollution wastes are found. Discharges of thermal waters into the sea have been detected corresponding, mainly, to coastal springs. Combined interpretation of Landsat data with air-photographs identified the main sources of water outflows and the regional tectonic structure. Such data constitute an ideal base for these studies by comparison or superposition with the other data, and effectively monitor changes in regional scales. Regional hydro-geological or geothermic investigations could be helped by the results of this study.
