Granulometry, geochemistry and mineralogy of fluvial sediment from the Gersprenz, Modau, Muemling, and Upper Neckar rivers, Germany

This dataset accompanies the manuscript entitled \"Temporal and Granulometric Variability of Fluvial Sand Composition: An Annual Time Series from Four Rivers in SW Germany\" by Laura Stutenbecker et al., submitted to JGR Earth Surface in March 2023. The study aims at analyzing the temporal variability of fluvial sediment composition. For this purpose, sediment of four rivers was sampled monthly over the course of one year between April 2019 and December 2020 at the same locations, using the same operator, tools, and sampling strategy, resulting in a total of 46 grab samples. The sampled rivers were the Gersprenz, Modau, Mümling and Upper Neckar rivers in southwestern Germany. […]
