rECOmine: ResuS - Recycling of subhydric sediments

The Federal Ministry of Education and Research (BMBF) funds innovative projects within the framework of the program “We – Change for through innovation in the region”. Here, the rECOmine-alliance focuses mainly on topics such as the usage and winning of (secondary) raw materials.
In this frame, Veolia, the Ceramic Institute Meißen, PICON and GeoWiD have united under the leadership of the chair of Hydrogeology and Hydrochemistry at TU Bergakademie Freiberg as partners in the project ResuS to face the problem of ongoing siltation in dams and barrages. GeoWiD GmbH starts the project in June, 2023 to develop a procedure for the removal of representative, undisturbed samples of subhydric sediments which represents a single part of the overall project “ResuS - Recycling of subhydric sediments”.
The aim is to analyze and show potential ways of utilization of subhydric sediments from Saxonian dams and barrages. For this a sufficient amount of a sampling material is essential in order to give the other partners of the alliance a basis for their further and ongoing investigations. An appropriate sampling method needs to be developed which guarantees the preservation of layering as well as an undisturbed sampling by scientific divers.
The sampling will be done on a long-term basis as a part of a monitoring concept which is yet to be developed. The samples will be analyzed in our laboratory for soil mechanics.

We thank all the partners of the project as well as LTV Sachsen for the cooperation during the time application. We are looking forward to a cooperative and successful research project within the next three years.
