Granular Dynamics of Natural Sediment

This archive contains data and videos collected in experiments examining the influence of a finer grain input to a coarser granular bed driven by a shallow fluid flow. The experiments were undertaken in the River Dynamics Laboratory at Simon Fraser University between October 2015 and February 2016. The first set of runs was undertaken using spherical glass beads. The second set with natural fluvial sediment. The file 'Experimental_Conditions_Dudill_etal_Granular_Dyanmics_Natural_Sediment_Oct_21_2019.xlsx' contains information on sediment properties, flume dimensions, imposed hydraulic conditions, observed infiltration behavior, and measured parameters including flow depth and bed slope. Each run listed in this spreadsheet has a video file(s) showing characeristic granular motions. These data were published in Dudill, A., J.G. Venditti, M. Church, P. Frey (2020). Comparing the behavior of spherical beads and natural grains in bedload mixtures. Earth Surface Processes and Landforms, 45: 831-840. The file 'Supporting_Material_for_Church_etal_April_1_2020.xlsx' contains observations from select experiments in the River Dynamics Laboratory at Simon Fraser University, including some not reported in Dudill et al. (2020). Also included are select laboratory experiments conducted at the Institut National de Recherche en Sciences et Technologies pour l'Environnement et l'Agriculture (IRSTEA, now INRAE) in Grenoble, France and reported in Dudill et al., (2017; 2018; full references in document). The combined data set are published in Church M., A. Dudill, J.G. Venditti, P. Frey (2020). Are results in geomorphology reproducible?

Software used was Excel. This dataset was originally deposited in the Simon Fraser University institutional repository.
