<b>Measurement of granular flow dynamics from laboratory flume experiments</b>

The zip file <b>S1</b> is the raw measurements of granular flow dynamics from laboratory flume experiments. The excel file in the zip file is the measurements for each experiment condition. <i>M</i> represents the flow mass and contains 4 kinds of mass, 5kg, 10kg, 20kg and 40kg. <i>D</i> represents the particle size, including 3 particle sizes, 2mm, 4mm and 6mm. The excel file contains measurements of the base force, acceleration signal and flow height in two different monitoring areas.The zip file <b>S2</b> is the raw high-speed video of the granular flows. The data in this file can be used to analyze the dynamic processes and dynamics of granular flows, such as flow velocity.The zip file <b>S3</b> and <b>S4</b> contain the processed data, including basal force, acceleration signal, flow height, and flow velocity. See the included README.txt file for details.
