Abstract
The aim of this thesis is to investigate the morphology of debris fan by conduct a field survey in Pu-Tun-Pu-Nas River debris fan of Laonong River and experiment observation with the Photogrammetry survey method. Aerial UAV Photogrammetry survey with ground controlled marker target can bring high quality digital surface model in a parity cost. Designed mirror array build in laboratory can provide stereo images for reconstruct experiment debris fan topography. Two experiment conditions are adopted to simulate fluvial fan and mudflow formed composition pattern. These two formation pattern might be possible in the field according to the comparison result between field and experiment. The result of experiment shows these two experiments might reach a dynamic equilibrium elevation in late stage from an initial stage of elevation growth.
