Supporting data for the manuscript "New Paradigm of Unsaturated Erosion Model for Flow-type Landslides: Debunking the Importance of Frictional Shear stress"

The spreadsheet contains data obtained in the physical experiments. The experiments are simulation of erosion of unsaturated soil beds caused by flow-type landslides. More specifically, these data are:<br>(1) Time-history of the basal forces generated by dry gravel flows measured by the loadcell. The loadcell is installed on the rigid bed.<br>(2) The probability distribution of basal forces generated by flows with different flow particle size.<br>(3) The probability distribution of basal forces generated by flows with different Froude number.<br>(4) Test program and the properties of the flows and bed material.<br>(5) A summary of the test results.<br>(6) Erosion depth measured by the 14 erosion columns.<br>(7) A summary of the test data obtained by Hsu et al. (2008) in modelling of rock erosion. (Citation: Hsu, L., Dietrich, W. E., &amp; Sklar, L. S. (2008).
