Short summary
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.

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.

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.

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.

Luminescence properties of samples from the Rinikerfeld, northern Switzerland, are assessed. Reader-specific low preheat temperatures are invesigated to ensure suitable measurement conditions. While quartz is found to be dominated by stable fast components, signal loss is observed for feldspar and polymineral. In general, the ages of the fading corrected feldspar and the fine-grained polymineral fractions are in agreement with coarse-grained quartz, and ages indicate sedimentation during MIS6.

The Black Forest was covered by a 1000 km2 large ice cap during the last glaciation. Glacial landforms in the area north-west of the highest summit of the Black Forest, the Feldberg (1493 m above sea level), were investigated to select suitable sampling sites for dating glacial landforms in future studies. Some of the terminal moraines described in this study are mapped for the first time. The application of dating methods will provide insights into the chronology of the last glaciation.

PalaeoCADIX-Z is an interdisciplinary project that studied three cores drilled in a marine palaeochannel that ran through the ancient city of Cádiz (Spain). These cores reveal a ≥ 50 m thick Holocene sedimentary sequence. Importantly, most of the deposits date from the 1st millennium BCE to the 1st millennium CE. Geoarchaeologists, geomorphologists, archaeologists, sedimentologists, palaeoenvironmentalists, geochemists, and geochronologists collaborated within this project.

Fluorescent tracers such as uranine and sulforhodamine B are useful tools to gain knowledge about water and solute fluxes in aquatic and terrestrial ecosystems. In this study we systematically investigated the influence of important soil properties (pH, organic carbon content and texture) on tracer adsorption in soils and sediments. These properties also determine whether the tracers in the respective soil behave conservatively or non-conservatively.

Recharge assessment in the shared transboundary Western Aquifer Basin is highly relevant, scientifically as well as hydropolitically (in Israeli–Palestinian water negotiations). Our unique combination of field-measured soil characteristics and soil moisture time series with soil moisture saturation excess modelling provides a new basis for the spatial differentiation of formation-specific groundwater recharge (at any scale), applicable also in other previously ungauged basins around the world.

In this study we explore the use of hydrological tracers coupled with high vertical resolution sampling and monitoring to evaluate temporal and spatial mechanisms that dominate transport and dissipation of pesticides in a laboratory-scale constructed wetland. Our results reveal different transport vectors and dissipation pathways of solutes over time and space that are influenced by the constructional design, the presence of plants and the alternation of different hydrological conditions.

Deposits related to the last advance of Reuss Glacier are dated using a luminescence methodology. An age of 25 ka for sediment directly overlying the lodgement till corresponds with existing age constraints for the last maximal position of glaciers. Luminescence dating further implies an earlier advance of Reuss Glacier into the lowlands during Marine Isotope Stage 4. The data are discussed regarding potential changes in the source of precipitation during the Late Pleistocene.

Provided here are novel data concerning site formation processes and Middle Palaeolithic human presence at Cotencher cave (Switzerland). A local glaciation around 70 ka was followed by ice-free conditions, when artefacts and faunal remains were displaced by solifluction processes. Evidence of local glacier development around 36 ka is also presented. This interdisciplinary study contributes new elements for the understanding of climatic changes and human passage in the central Jura Mountains.

Fluorescent tracers such as uranine and sulforhodamine B are useful tools to gain knowledge about water and solute fluxes in aquatic and terrestrial ecosystems. In batch experiments, we investigated systematically the influence of pH, organic carbon and texture on tracer adsorption on soils and sediments and quantified their impact and possible interactions. Overall, the investigated controls determine if the respective tracer shows more conservative or more non-conservative transport behaviour.

About 25 000 years ago, Alpine glaciers filled most of the valleys and even extended onto the plains. In this study, with help from traces left by glaciers on the landscape, we use a computer model that contains knowledge of glacier physics based on modern observations of Greenland and Antarctica and laboratory experiments on ice, and one of the fastest computers in the world, to attempt a reconstruction of the evolution of Alpine glaciers through time from 120 000 years ago to today.

In this study we show the relevance of an interdisciplinary study for improving restoration within the framework of a European LIFE+ project on the French side of the Upper Rhine (Rohrschollen Island). Our results underscore the advantage of combining functional restoration with detailed knowledge of past trajectories in complex hydrosystems. We anticipate our approach will expand the toolbox of decision-makers and help orientate functional restoration actions in the future.

Here we investigate the suitability of a specific low-cost water filter for drinking water treatment in households of rural South Africa. Distributed in the field, none of 51 individually tested water filters produced water without distinct contamination, and more than one-third even deteriorated hygienic water quality. We therefore recommend frequent monitoring of the filter performance at the point of use and identify dip slides as an efficient tool to assess critical contamination.

Soil moisture was observed along a strong semi-arid climatic gradient in a Mediterranean karst area. Soil moisture data and soil hydraulic modelling with Hydrus-1D revealed a strong dependency of percolation fluxes with rainfall amounts and intensity during heavy rainfall events. Spatial and temporal extrapolation of the model illustrated the high variability of seasonal percolation amounts among single years and showed strong correlations between soil depth and potential groundwater recharge.

To solve the issue of sparsity of field-observed runoff data, we propose a methodology that leverages taxi GPS data to support hydrological parameter calibration for road networks. Novel to this study is that a new kind of data source, namely floating car data, is introduced to tackle the ungauged catchment problem, providing alternative flooding early warning supports for cities that have little runoff data but rich taxi data.

We studied water partitioning under urban grassland, shrub and trees during a warm and dry growing season in Berlin, Germany. Soil evaporation was highest under grass, but total green water fluxes and turnover time of soil water were greater under trees. Lowest evapotranspiration losses under shrub indicate potential higher drought resilience. Knowledge of water partitioning and requirements of urban green will be essential for better adaptive management of urban water and irrigation strategies.

This work demonstrates a new approach to obtain flood level trend information from surveillance footage with minimal prior information. A neural network trained to detect flood water is applied to video frames to create a qualitative flooding metric (namely, SOFI). The correlation between the real water trend and SOFI was found to be 75 % on average (based on six videos of flooding under various circumstances). SOFI could be used for flood model calibration, to increase model reliability.

With a growing urban flood risk worldwide, flood risk management tools need to be validated against reference data. Field and remote-sensing observations provide valuable data on inundation extent and depth but virtually no information on flow velocity. Laboratory scale models have the potential to deliver complementary data, provided that the model scaling is performed carefully. In this paper, we reanalyse existing laboratory data to discuss challenges related to the scaling of urban floods.

This paper reviews how weather radar data can be used in urban hydrological applications. It focuses on three areas of research: (1) temporal and spatial resolution of rainfall data, (2) rainfall estimation, radar data adjustment and data quality, and (3) nowcasting of radar rainfall and real-time applications. Moreover, the paper provides examples of urban hydrological applications which can benefit from radar rainfall data in comparison to tradition rain gauge measurements of rainfall.

Recent developments have made it possible to easily crowdsource meteorological measurements from automatic personal weather stations worldwide. This has offered free access to rainfall ground measurements at spatial and temporal resolutions far exceeding those of national operational sensor networks, especially in cities. This paper is the first step to make optimal use of this promising source of rainfall measurements and identify challenges for future implementation for urban applications.

Commercial microwave links (CMLs) can provide rainfall observations with high space–time resolution. Unfortunately, CML rainfall estimates are often biased because we lack detailed information on the processes that attenuate the transmitted microwaves. We suggest removing the bias by continuously adjusting CMLs to cumulative data from rain gauges (RGs), which can be remote from the CMLs. Our approach practically eliminates the bias, which we demonstrate on unique data from several CMLs and RGs.

Short summary
A new lightning data assimilation method has been implemented and validated within the Finnish Meteorological Institute – Local Analysis and Prediction System. Lightning data do improve the analysis when no radars are available, and even with radar data, lightning data have a positive impact on the results.
We also investigate the usage of different time integration intervals: 1, 6, 12, 24 h and 7 days, where the 1 h integration time length gives the best results.

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.
