Bottom Sediments from a Dam Reservoir as a Core in Embankments—Filtration and Stability: A Case Study

A possibility of using bottom sediments from dam reservoirs in earth structures was considered. Sediments the Rzeszow reservoir (Poland) were used as research material, which, according to geotechnical standards, classified low permeable silt with high organic content. As fine, cohesive soil a coefficient permeability, can be sealing elements hydraulic engineering embankments. In order verify suitability sediments, stability and filtration calculations carried out for embankments form core made sediments. It stated that by volume seepage on downstream side during continuous or variable backwater significantly lower relation an embankment without core, phreatic line did not extend slope. is estimated that, case planned dredging Reservoir, amount dredged sediment would exceed 1.5 million m3, therefore, their economic use essential. The search materials could replace natural earthen important issue both ecological points view.
