Abstract The Weierbach experimental catchment (0.45 km 2 ) is the most instrumented and studied sub‐catchment in Alzette River basin Luxembourg. Within last decade, it has matured towards an interdisciplinary critical zone observatory focusing on a better understanding of hydrological hydro‐geochemical processes. embedded elevated sub‐horizontal plateau, characterized by slate bedrock representative Ardennes Massif. Its climate semi‐marine, with precipitation being rather evenly distributed...
To gain a better understanding of tree vulnerability to drought stress, we need observe when and where stress occurs. Established techniques tend be limited by technical shortcomings in monitoring environmental plant conditions at appropriate temporal spatial scales. New overcome limitations are becoming available, but they must benchmarked tested range conditions.Thermal infrared (TIR) remote sensing allows detection because down-regulated transpiration due water shortage also reduces...
In order to precisely quantify the contribution of anthropogenic activities and geogenic sources dissolved suspended loads rivers we have combined for first time Rare Earth Element (REE) concentrations with Sr–Nd–Pb isotope ratios. We observed enrichments in Anthropogenic Elements (AREE) (Gd) (Ce Nd) river water. During flood events, AREE anomalies progressively disappeared gave way chemical signature basin both loads. The isotopic data confirm these observations shed new light on trace...
Enrichments in Gd and LREE/HREE fractionation have been observed for the dissolved colloidal fractions waters of Alzette River during low flow conditions. They can be related to effluents waste water treatment plants (Gd/Gd*: 8-380 LaN/YbN: 0.02-0.07). Mean daily flux balance calculations at basin scale show that conditions only comes from anthropogenic effluents. When flood events occur, anomaly progressively disappears gives way a chemical signature, which is closer natural REE sources...
Subsurface flow is often recognized as a dominant runoff generation process. However, observing subsurface properties, and understanding how they control pathways, remains challenging. This paper investigates surface slope bedrock cleavage pathways in slate headwater catchment Luxembourg, characterised by double-peak streamflow response. We use range of experimental techniques, including field observations soil characteristics, sprinkling experiment at site located 40 m upslope from the...
Sediment fingerprinting is used to identify catchment sediment sources. Traditionally, it has been based on the collection and analysis of potential soil sources target sediment. Differences between source properties (i.e., fingerprints) are then discriminate sources, allowing quantification relative contributions The traditional approach generally requires substantial resources for sampling fingerprint analysis, when using conventional laboratory procedures. In pursuit reducing required,...
Abstract. With flash flood events having been repeatedly observed in Central and Western Europe recent years, there is a growing interest how catchment physiographic properties hydrological conditions are eventually controlling rapid concentrated responses. Here we focus on set of two nested catchments Luxembourg (Europe) that have exposed 2016 2018 to study their seasonal runoff time transfer distributions. Both similar size (∼ 30 km2) analogous distance distributions, but geological...
Abstract Soil water content (SWC) is a fundamental variable involved in several hydrological processes governing catchment functioning. Comparative analysis of different catchments based on SWC data therefore beneficial to infer driving factors response. Here, we explored the use high‐temporal resolution three forested (2.4–60 ha) European climates characterize responses during wet and dry conditions. The investigated systems include Ressi, Italy, with humid temperate climate, Weierbach,...
Abstract Hydrological processes research remains a field that is severely measurement limited. While conventional tracers (geochemicals, isotopes) have brought extremely valuable insights into water source and flowpaths, they nonetheless limitations clearly constrain their range of application. Integrating hydrology ecology in catchment science has been repeatedly advocated as offering potential for interdisciplinary studies are eventually to provide holistic view functioning. In this...
