Abstract The synthesis of experimental understanding catchment behaviour and its translation into qualitative perceptual models is an important objective hydrological sciences. We explore this challenge by examining the cumulative hydrology three catchments how it evolves through application different investigation techniques. case study considers Huewelerbach, Weierbach Wollefsbach headwater Attert basin in Luxembourg. Subsurface investigations including bore holes pits, analysis soil...
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...
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...
The formation, functioning and emergent properties of patterned landscapes have recently drawn increased attention, notably in semi-arid ecosystems. We describe analyze a set similarly spectacular landforms seasonal tropical wetlands. Surales landscapes, comprised densely packed, regularly spaced mounds, cover large areas the Orinoco Llanos. Although descriptions surales date back to 1940's, their ecology is virtually unknown. From data on soil physical chemical properties, macrofauna,...
Abstract. Within the critical zone, regolith plays a key role in fundamental hydrological functions of water collection, storage, mixing and release. Electrical resistivity tomography (ERT) is recognized as remarkable tool for characterizing geometry properties regolith, overcoming limitations inherent to conventional borehole-based investigations. For exploring shallow layers, small electrode spacing (ES) will provide denser set apparent measurements subsurface. As this option cumbersome...

Electrical Resistivity Tomography (ERT) is recognized as remarkable tool for characterizing geometry properties regolith, overcoming limitations inherent to conventional borehole-based investigations. However, ERT measurements with high vertical resolution remain restricted shallow depths, essentially due requirement small electrode spacing...
It was time to take stock. We modified the humipedon classification key published in 2018 make it easier and more practical. This morpho-functional taxonomy of topsoil (humipedon) only available English; we also translated into French Italian. A standardized humipedons (roughly top 30–40 cm soil: organic organomineral surface horizons) would allow for a better understanding functioning soil ecosystem. paper provides founding principles humus systems forms. With recognition few diagnostic...
The dominant processes concept was used to develop a regionally applicable rainfall—runoff model. first-order runoff are identified through combination of field investigations, physico-geographical analysis the research area, Alzette River basin in Grand-Duchy Luxembourg, and discharge data series analysis. Lithology appeared be major source discrepancy hydrological behaviour over total area. As result, each lithological substratum characterized conceptualized into parsimonious model...
Abstract Three different statistical models were used to regionalize the winter stormflow coefficient for mesoscale basins of Grand Duchy Luxembourg and neighbouring Rhineland Palatinate (Germany). The methodology is derived from a previous study, in which coefficients regionalized only. are based on regression analysis it shown that model performances do not differ considerably between parsimoniously heavily parameterized models. Next, regionalization procedure raster grid was performed,...
Abstract Diatoms are unicellular eukaryotic algae that widely distributed in aquatic environments. In particular, their presence is abundant stream flows, whereas the instance and transport of cells through subsurface flow controversial. this work, we study diatoms soils by designing laboratory percolation experiments on undisturbed loamy sandy soil cores. To label diatom tracers enhance detectability, develop protocols to functionalize frustules purified diatomite Conticribra weissflogii...
