In situ rates of reductive dissolution in submerged shoreline sediments at Lake Tegel (Berlin, Germany) were measured with a novel hydrous manganese (Mn) oxide-doped gel probe sampler in concert with equilibrium gel probe and sequential extraction measurem ...
Sediment transport hysteresis occurs due to the different sediment fluxes for the same discharge on the rising and falling limb of the overland flow hydrograph. Experimental field data has shown that the common shapes of the hysteresis loops encompass (i) ...
Reservoir sedimentation and the resulting storage losses impact reliability, efficiency, safety and thus the sustainability of the hydropower schemes. Beside traditional storage hydropower plants, also pumped-storage facilities are affected. Flexible turbi ...
Confluences between small steep tributaries with dominant supply of poorly sorted sediment and larger main channels with dominant flow supply, which are characterized by a pronounced bed discordance, have not yet been considered in the literature. The hydr ...

Reservoir sedimentation is worldwide a significant long term problem and requires in view of the current mitigation measures an alternative and more sustainable solution. This challenge motivated the present study with the purpose to develop an alternative ...
The overall dam-break phenomenon is currently well understood for reservoirs filled with water. However, many dams face serious problems of reservoir sedimentation. Thus, regarding risk management, the influence of a large amount of sediment in the reservo ...
We quantified the areal hypolimnetic mineralization rate (AHM; total areal hypolimnetic oxygen depletion including the formation of reduced substances) in two formerly eutrophic lakes based on 20 yr of water-column data collected during oligotrophication. ...
Mobilization of arsenic (As) in the subsurface environment can result in elevated concentrations of As in groundwater and potential human exposure and adverse health effects. Natural attenuation (i.e., sequestration) of As may, under appropriate geochemica ...
Shallow reservoirs are threatened by fast filling up with sediments, even if the entering sediments are only suspended loads. The sedimentation process is strongly influenced by the geometry of such shallow reservoirs. In the framework of a research projec ...
