----------------------------------------------------------------------------------------------------------------------------------------------------------------- Data collected from the project "Experimental Investigation of Sediment Stability at Reservoirs on the Rhône River" Details on the project including information on the materials and methods applied are provided in the available technical report ----------------------------------------------------------------------------------------------------------------------------------------------------------------- A_Bulk_Density - contains the vertical bulk density measurements of all withdrawn sediment cores from the Motz and Logis-Neuf reservoir Motz: MZ08, MZ09, MZ10, MZ11, MZ12, MZ13, MZ14, MZ15, MZ16 Logis-Neuf: LN01, LN02, LN03, LN04, LN05, LN06, LN07, LN08, LN09, LN10, LN11, LN12, LN14 ----------------------------------------------------------------------------------------------------------------------------------------------------------------- --> selected cores for detailed experimental investigations: MZ09, MZ14 and LN10, LN14 B_Sediment_Composition_and_ParticleSizes - contains the results of the depth-dependent particle size analyses (distribution curves) - contains the derived sediment composition over core depth C_TOC_and_CEC - contains the results of the Total Organic Carbon (TOC) measurements over core depth - contains the results of the Cation Exchange Capacity (CEC) measurements over core depth D_Sediment_Stability - contains the results of the measured sediment stability over core depth E_Sediment_Erosionrates - contains the results of the measured erosion rates over core depth --> two methods are considered: "last measured erosion rate" and "mean erosion rate" F_Sediment_Erosion_Volumes - contains the raw data of the erosion volume measurements conducted with SETEG/PHOTOSED --> the data is provided separately for each investigated sediment layer over core depth (denoted by "D**") --> the data is evaluated for five considered time intervals dt =15s, dt =30s, dt =60s, dt =100s, dt =120s -----------------------------------------------------------------------------------------------------------------------------------------------------------------
