In general, geomorphological landforms are viewed as Boolean objects. However, recent studies have shown that landforms are more suitable to be viewed as fuzzy objects, whereby a landform is defined as a region in the continuum of variation of the surface of the earth. In this study, the fuzzy classification of simulated droughts and floods of water bodies is performed. First, concepts of mathematical morphology are employed to generate simulated droughts and floods of water bodies. Fuzzy classification is then performed based on by the average of Boolean memberships of the water bodies over the levels of droughting and flooding. The proposed fuzzy classification method is useful for statistical analyses and determination of sample schemes.
