2011 m. Nr. 2 Usability evaluation of bottom sediments from Czorsztyn–Niedzica reservoir backwater in geotechnical engineering
The paper presents the geotechnical characteristics and heavy metal contents in bottom sediments of the Czorsztyn–Niedzica reservoir backwater and the evaluation of their usability for geotechnical engineering. The bottom sediments were classified as cohesive humus silts and the soils below that depth as non-cohesive (silty and medium sands). The analysis of cadmium, zinc and lead content showed a low concentration of these metals in the sediments on the geotechnical background level. Only copper content showed an increased concentration, but it did not exceed the class II of sediment purity. The tested sediments did not fulfil most of the required criteria and thus they rather cannot be used for geotechnical engineering purposes. However, in case of sediment extraction, there is a possibility of improving their granulation or stabilization with a hydraulic binding agent.
