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.本数据集包含本文实测得到的7组滑坡坝三维几何形态点云数据（point cloud data），该部分数据为稿件中图3与图4的原始数据。 另有Excel格式数据集，收录42例滑坡坝历史案例，涵盖滑坡坝发生地点以及详细几何参数。
