----------------------------------------------------------------------------------------------------------------------------------------------------------------- Data used in the publication "Functional relationships between critical erosion thresholds of fine reservoir sediments and their sedimentological characteristics", which is accepted by the Journal of Hydraulic Engineering and will be published in a forthcoming issue. Beckers, F., K. Koca, S. Haun, M. Noack, S. U. Gerbersdorf, and S. Wieprecht. Forthcoming. „Functional relationships between critical erosion thresholds of fine reservoir sediments and their sedimentological characteristics.” J. Hydraul. Eng. https://doi.org/10.1061/(ASCE)HY.1943-7900.0001984 The data consists of two files: GBS.txt contains the sediment data of the reservoir Großer Brombachsee SBT.txt contains the sediment data of the reservoir Schwarzenbachtalsperre Both files contain information on the sediment depth and erosion stability separated into τc,0 and τc,S. Furthermore, both files contain a collection of physico-chemical sediment parameters, including bulk density, sediment composition (Clay, Silt, Sand), percentiles (d10, d50, d90),cation exchange capacity (CEC), and organic content (TOC). Additionally, the SBT data contains biological sediment parameters, including chlorophyll-a (CHL-a), and extracellular polymeric substances separated into proteins (EPS-p) and carbohydrates (EPS-c). ----------------------------------------------------------------------------------------------------------------------------------------------------------------- The data was collected within the transdisciplinary research project "CHARM - Challenges of Reservoir Management". -----------------------------------------------------------------------------------------------------------------------------------------------------------------
