Abstract: | The aim of this study was to introduce a new morphometric index named Relief Index (RI). RI is the ratio of the total length of the contour lines and the surface area at which they occur. This easily calculated index provides an objective quantitative measure of relief variability as an important feature in geomorphological studies. To achieve this goal, a highly detailed morphometric analysiswas carried out using a high-resolution (1m×1m) DEM. Twenty one sample areas in southern Poland were examined. These analyses showed RI, as a good tool for rapidly evaluating topography heterogeneity in division into relief classes. I distinguished 4 classes of the Relief Index that classify earth surface considering the variability of the relief. Results of the calculations demonstrated that there is a significant correlation between RI and the local relief and slopes, but there is no correlation between RI and planar curvatures and TWI. The relief of the sample areas were analysed using geomorphometric parameters (slopes, local relief, planar curvatures).Moreover the influence of the DEM resolution on Relief Index values was examined. |
