Reconnaissance geophysical survey for the detection of salinization and stratigraphy in Thorikos Valley, Attica, Greece

A reconnaissance geophysical survey is a starting task of a multitasking collaboration to detect all hydrogeological (extent of salinization), stratigraphical, geological features of Thoriko valley in order to reconstruct the environment in ancient times as well as to interpret the position of the various archaeological monuments existing in the area. Electromagnetic measurements with conductivity meter, made in a quick mode with a cart dragged by car, have given, after data evaluation and filtering, valuable information regarding near surface salinization phenomenon. In addition ERT and IP profiles give deeper detection of this phenomenon discriminating media of various clayey content.
