This paper introduced the basic principles of laser scanning technology(LIDAR)
and specified the method of application the LIDAR to dynamically monitor gully erosion processes
which included measuring preparation
scanning survey process
point cloud preprocessing
coordinate transformation
TINs generation and soil loss estimation.Taking the experimental study on the gully erosion processes by simulating rainfall as a study case
dynamic monitoring method of gully erosion process using LIDAR was described in detail
which comprised field data collection
point cloud analysis
and mesh modeling.Comparison of the measured soil loss and the estimated soil loss showed that LIDAR technology has high accuracy to monitor soil erosion
and the estimating accuracy reaches to 96.85%.It suggests that the LIDAR should be combined with GPS technology to monitor gully erosion in field experiment.
