    The aim of this paper is to use an automated approach to challenge the cyclicity of the bare Earth surface phenomena, in our case dolines on the selected different lithological karstic environments ... in Slovenia. The solution is based on a digital elevation model (DEM) datasets with a resolution of 1, 5 and 12.5 m, applying a one-dimensional Fast Fourier transform (FFT). The Fast Fourier transform was applied on a number of the star form profiles that were positioned to the 11 selected areas with different geological settings. Since the cyclicity/periodicity of the Karst surface in Slovenia was already confirmed manually in the 1980s, we confirmed it using digital data, corresponding algorithms of the Fourier analysis, on the smoothed and normalized profiles. Since the main problem is preprocessing datasets and interpretation of the results, further solutions in this direction are proposed, such as employing other methods for normalization of the digital elevation model.
