Flow and clay erosion data taken and processed at SAFL in a grid-turbulence tank Summer 2022

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.
