Mixing within confluences is highly variable.This study relates patterns and amounts of mixing to three‐dimensional flow structure at three small confluences. The study indicates that generalization of mixing at confluences remains challenging but that advective lateral fluxes of streamwise momentum related to secondary currents or primary flow greatly enhance mixing at confluences.

The authors have investigated whether and to what extent mining products from the Lusatian mining are deposited in the sediments of the River Spree: their signature in the river bed reaches 90 kilometres.

Eutrophication of Lake Stechlin leads to changes in the sediment by an intensification of internal matter cycles. The reductive dissolution of Mn in shallow areas and the precipitation result in the fixation of Mn as rhodochrosite in the sediment below 56 m depth. Geochemical Mn focusing indicates oxygen-free conditions in deep water and can be used to reconstruct former environmental conditions.

A predator-prey model shows the coupled dynamics of groundwater use and crop production. It provides the scientific basis for the sustainability analysis of the irrigation of agricultural land with groundwater.

To better understand the production and loss processes of methane and carbon dioxide in water bodies, their concentrations need to be measured with high spatial and temporal resolution. For continuous in situ measurement of CH4 and CO2 dissolved in water, researchers from IGB developed a Fast-Response Automated Gas Equilibrator (FaRAGE).
