Data for: Laboratory-scale investigation of the 3-D geometry of landslide dams in a U-shaped valley

The data includes the point cloud data of 7 sets of the three-dimensional geometry of landslide dams measured in this paper. These are the raw data for figures 3 and 4 in the manuscript. The data in excel format are 42 historical cases of landslide dams, including the occurrence site of landslide dam and detailed geometry parameters.
