Hydrological and geochemical data from natural waters during a 26-day flood event in the Weierbach experimental catchment (WEC), Luxembourg

This publication contains the dataset of the manuscript submitted to Water Resources Research entitled "High-frequency multi-isotope and multicompartment sampling of a flood event reveals mixing and reaction network shifts as drivers of Concentration-Discharge relationships" by López-Urzúa et al. This dataset contains geochemical data, rainfall records, groundwater waterlevel, and stream discharge data collected during a 26-day flood event in the Weierbach experimental catchment (WEC), Luxembourg. The presented data are originally contained in López Urzúa, S. (2024), Isotopic tracer constraints on concentration-discharge relations in the Critical Zone [Doctoral dissertation, Université Paris Cité, Institut de Physique du Globe de Paris] Contents:Table 1.
