ABSTRACT
This chapter attempts to apply the advanced RS and GIS technology to study landslide susceptibility assessment in the study area in TGP reservoir region. It aims to assesss landslide susceptibility by the algorithm of fuzzy logic. Fuzzy Logic, a generalization of classical set theory, is very attractive for the evaluation of landslide susceptibility, due to its capability of transporting to the mathematical field, the subjective, inductive and deductive judgments that are essentials in such a comprehensive study. Fuzzy logic has the advantage to take into consideration the expert’s experience in order to transform it into membership degree and rule base in the evaluation of landslide susceptibility. Landslide susceptibility map in the study area, expressed as probability of occurrence. Logic could determine the fuzzy membership value for evidential map of the main factors based on the actual occurrence of the known landslides and the experiences and knowledge of the experts on the regulation of the landslides in the area.
