We developed the first global database of water from karst springs and cave drips that records different forms of oxygen and hydrogen, which naturally trace how rainwater moves through rocks. By gathering and checking thousands of measurements from around the globe and linking them with flow and rainfall data, the database provides a comprehensive view of water movement, allows scientists to compare regions, understand groundwater processes, and support sustainable water management worldwide.

It is unclear since when and how meso-scale central European river systems have been dominated by human instead of natural influences. Here, the floodplain sediments of the Kinzig River, southwestern Germany, were studied as they recorded natural and human landscape changes. Sediment deposition phases were found, the modern phase of which coincides with increased deposition and heavy metal contaminations that correlate with mining records, indicating that the river system has shifted intensely over 1000 years.

This study examines the evolution of the lower Bruche River valley in north-eastern France through its fluvial terraces, reflecting past river dynamics and environmental changes. Terrace formations are dated using luminescence to ~ 12–14 ka, ~ 27–35 ka, and at least 200 ka. Methodological improvements over conventional luminescence dating techniques are also discussed and refined in this study.

We studied trifluoroacetate (TFA) in a German river catchment. TFA from rain is not permanently retained in soils or plants and can be washed out by heavy rain, meaning soils and plants may hold more TFA than rivers or rainfall indicate. In rain-fed areas, TFA served as a new tracer for evapotranspiration. Agricultural areas showed higher TFA in surface and groundwater, suggesting that agriculture increases TFA pollution.

Previous reconstructions conclude that the southern Black Forest, south-west Germany, temporarily hosted four ice caps during the Late Pleistocene (129 000–11 700 years before present). This work reviews existing studies on glacial landforms north-east of its highest summit, Feldberg (1493 m above sea level), in the light of new observations. Whilst this study largely confirms previous work, we reject and newly describe several glacial landforms.

The Mühlbach series has been given as evidence for a Late Pliocene/Early Pleistocene Aare–Rhine fluvial system in northern Switzerland and southwest Germany. We show that these deposits represent a variety of different units. At the type location, luminescence dating indicates an age of 55 ka, and we interpret the deposits as slope reworking. Beside methodological implications, our studies recommend caution regarding the interpretation of stratigraphic units for which limited data are available.

The Tannwald Basin, explored by drilling and formed by repeated advances of the Rhine Glacier, reveals key geological insights. Ice-contact sediments and evidence of deformation highlight gravitational and glaciotectonic processes. ICDP DOVE 5068_1_C core data define lithofacies associations, reflecting basin infill cycles, marking at least three distinct glacial advances. Integrating these findings aids understanding the broader glacial evolution of the Lake Constance amphitheater.

We determined 10Be concentrations in moraine boulder surfaces in the southern Black Forest, SW Germany. We applied three independent dating methods to younger lake sediments. With the aid of independent age datasets, we calculated the growth of 10Be concentrations in moraine boulder surfaces.

The loess sequence of Köndringen, Upper Rhine Graben, comprises several glacial–interglacial cycles. It has been investigated using a multi-method approach including the measurement of colour, grain size, organic matter, and carbonate content. The analyses reveal that the sequence comprises several fossil soils and layers of reworked soil material. According to luminescence dating, it reaches back more than 500 000 years.

Erosion processes below glacier ice have carved large and deep basins in the landscapes surrounding mountain ranges as well as polar regions. With our comparison, we show that these two groups of basins are very similar in their shapes and sizes. However, open questions still remain especially regarding the sediments that later fill up these basins. We aim to stimulate future research and promote exchange between researchers working around the Alps and the northern central European lowlands.

Short summary
Previous glaciations eroded below the ice deep valleys in the Alpine foreland, which, with their sedimentary fillings, witness the timing and extent of these glacial advance–retreat cycles. Drilling such sedimentary sequences will thus provide well-needed evidence in order to reconstruct the (a)synchronicity of past ice advances in a trans-Alpine perspective. Eventually these data will document how the Alpine foreland was shaped and how the paleoclimate patterns varied along and across the Alps.

We used a combination of remote sensing, field investigations, and laboratory analysis to map and characterize abandoned river channels within the French Upper Rhine alluvial plain. Our results show five major paleochannel groups with significant differences in their pattern, morphological characteristics, and sediment filling. The formation of these paleochannel groups is attributed to significant changes in environmental processes in the area during the last ~ 11 700 years.

Short summary
A loess sequence in SW Germany was investigated using a high-resolution multi-method approach. It dates to 34–27 ka and comprises layers of initial soil formation. Drier conditions and a different atmospheric circulation pattern during the time of deposition are expected as the soil layers are less strongly developed compared to similar horizons further north. Dust accumulation predates the last advance of Alpine glaciers, and no loess deposition is recorded for the time of maximum ice extent.

We analyzed variability in diel nitrate patterns at three locations in a lowland stream. Comparison of time lags between monitoring sites with water travel time indicated that diel patterns were created by in-stream processes rather than transported downstream from an upstream point of origin. Most of the patterns (70 %) could be explained by assimilatory nitrate uptake. The remaining patterns suggest seasonally varying dominance and synchronicity of different biochemical processes.

We investigated the linkage between contaminant mobilization in catchments and their mitigation in vegetated treatment systems (VTSs). We identified different patterns in chemographs recorded at the inlet of a VTS, indicating distinct mobilization patterns that were associated with similar source areas, transport pathways, and discharge dynamics. Peak concentration reduction in the VTS was strongest for sharp-peaked chemographs, suggesting that dispersion was the principle mitigation process.

Short summary
We used a two-step approach with limited sampling effort in existing storm water infrastructure to illustrate the risk of biocide emission in a 2 ha urban area 13 years after construction had ended. First samples at a swale confirmed the overall relevance of biocide pollution. Then we identified sources where biocides were used for film protection and pathways where transformation products were formed. Our results suggest that biocide pollution is a also continuous risk in aging urban areas.
