Between Dec 19, 2024 and Jan 2, 2025, datasets can be submitted to DRUM but will not be processed until after the break. Staff will not be available to answer email during this period, and will not be able to provide DOIs until after Jan 2. If you are in need of a DOI during this period, consider Dryad or OpenICPSR. Submission responses to the UDC may also be delayed during this time.

Abstract

Here we present a dataset containing raw imaging and processed data on clay erosion. This new dataset expands and complements the information located at https://doi.org/10.13020/vxrv-7e20. This dataset supports our study of the impact of salinity and consolidation on the microstructure and erosion threshold of cohesive sediments. The erosion measurements were taken inside a grid-turbulence tank at the St. Anthony Falls Laboratory at the University of Minnesota Twin Cities. We set the water salinity at a prescribed concentration in part-per-thousands and two clay consolidation conditions (unconsolidated and consolidated after 17 hours) for each experimental case. Here we incorporate laponite (smectite clay)'s surface erosion from laser-induced fluorescence and image processing.

Description

The raw data consists of fluorescence-labeled clay's surface imaging of the clay dispersion (clay microstructures). The processed data includes (i) time series of image structural-similarity index for clay erosion and (ii) erosion threshold in turbulent kinetic energy and bed shear stress. We release this dataset to make it available for understanding, evaluating, and building upon our reported research.
