Datasets for experimental granular flows

These datasets provides the measured and calculated data for the flume experiments of granular flow including parameters reflecting the granular flow behavior, basal normal stresses measured by a force plate, and deposit parameters of the experimental granular flows. The movies of the granular flows under different experimental conditions during their propagation are also provided to show the granular flow behavior and its evolution. 

Dataset_S1. Data of granular flows under different experimental conditions obtained through particle image velocimetry (PIV) analysis, which include the velocity profiles with a 0.1 second time interval, the depth-averaged velocities, the depth-averaged shear rates,  and the solid inertial stresses. The images for PIV analysis were recorded by a high-speed camera.

Dataset_S2. Data of the basal normal stresses of the granular flows for all tests. The basal normal stresses include the raw data measured through a force plate, the mean normal stresses obtained by applying a moving window average filter, and the calculated fluctuating stresses.

Dataset_S3. Data of the granular flow thickness extracted by a image processing method based on the high-speed photographs. 

Dataset_S4. Parameters of the granular flow deposits for all test including the apparent friction coefficient and equivalent friction coefficient. The deposit parameters were calculated based on the digital surface model (DSM) of deposit.

Dataset_S5. Movies showing the side-view of the granular flows during their propagation.
