constructing ground control points for terrain change detection is very difficult.The DEM matching and deformation detection technique without control points were adopted to monitor the soil and water loss caused by debris-flow in Puwaigou
southwest of Sichuan Province during the past 30 years.The experimental results validate that the proposed method is practical for monitoring the terrain changes in the debris-flow area.
