Abstract

It is important to predict the occurrence of debris flow for engineers and engineering geologists. Especially the prediction of occurrence point of debris flow involves geological and geomorphological problems. When geomorphological development is controlled by geological feature, it must be possible that geomorphological analysis predicts the point where debris flow will occur. In this study, the analysis of geomorphology using fractal is attempted as fundamental work for the prediction of place where debris flow will occur. When the analysis is compared with topography and geology, it is shown that the fractal geometry is dependent upon the topographical feature and the geological structure at mountains regions. In these regions the debris flows occurred at the place where the contour of dimensions is dense. Therefore, if DEM (Digital Elevation Model) data will be made in more detail, it should be possible to predict the debris flow occurrence point.
