EFFECT OF DEM UNCERTAINTY ON GEOPHYSICAL MASS FLOW VIA IDENTIFICATION OF STRONGLY COUPLED SUBSYSTEM

With the recent advent of aerial photography, capturing high-resolution terrain information has provided new opportunities to simulate geophysical mass flow on high-resolution digital elevation models (DEMs). This gives a better understanding of the flow of debris that has a wide range of size. However, performing uncertainty quantification (UQ) of debris flow on an uncertain terrain profile, especially creating a hazard map, still poses a...
