Efficiency assessment of Wood's method indices in classification of dry landforms (Case study: Maranjab region)

Understanding of landforms and their distribution are basic needs of applied geomorphology and other Earth sciences to understand and evaluate of landforms development, slope stability studies and regional planning. Landforms have at least two features: the first they are result of last geomorphologic and geologic processes and second to determine the borders now geomorphologic processes. In this study assess the Performance of Wood’s method for detection and classification of landforms in Maranjab dry region. After extraction morphometric parameters; slope, cross-sectional curvature, minimum and maximum curvatures from DEM overlay indices with slope tolerance value 1and curvature tolerance value 0.01. Result show flat and plain areas with 49/8% are majority with ridge and channel. This study focused to automate extraction of elements morphometric of land surface using Wood method. Result showed wood method is efficient in general geomorphometry on Marajnab region and could to extract main classess using DEM. But in spicific Geomorphometry and ectrcat discret landform is required to develop and improve performance.
