The subproject aims at the development of morphodynamic and material basic information for the optimization of the discharge control of the Kelbra dam. An optimized discharge control should serve to make the input of fine sediments and - the aquatic biocoenosis in the Helme downstream of the dam endangering - substances as harmless as possible.
The following objectives were defined for the implementation of the subproject:
- Quantification of the sediment input into the river Helme as a result of seasonal discharge from the Kelbra dam.
- Characterization and evaluation of the effects on the channel sediment structure at defined watercourse cross-sections
- Elaboration of a correlation between sediment/solids concentrations (reference date measurements of filterable substances afS) and continuous turbidity measurements in the flowing wave.
