THE JĘDRÓW HISTORIC HYDROTECHNICAL SYSTEMA GEOARCHAEOLOGICAL AND RESTORATION STUDIES (HOLY CROSS MOUNTAINS, POLAND)

Abstract

The purpose of recognizing the hydrotechnical infrastructure and metallurgical activity traces state is to provide restoration protection to Jędrów water mill building and its surrounding area. In the past, this area was used economically and was a part of the Old Polish Industrial District (central Poland). Jędrów is an example of disappearance of industry development, anyway the hydrotechnical infrastructure is still preserved here and visible even on the digital elevation model (DEM). Infrastructure elements such as embankments, channels and former pond basin are clearly visible here. The obtained echograms from GPR survey show geological changes that may reflect sediments filling the currently landed industrial pond. Well visible anomalies are most likely related to the slag deposits. Preliminary results from macro- and micro-slag analysis were obtained, which revealed the presence in overbank sediments of a large number of microscopic iron spheres (balls) indicating the accumulation of metallurgical activity material.
