Landform classification using topography position index (Case study: southern Darab Township)

Landform is a complication of land or landscape the establishment of which is formed by natural processes that can be described and defined by diagnosis index and if detected، the Landform information about their structure and composition، texture or its integrated offers. Landform variety and diversity of participants، mainly by changing the shape and position of the controls placed. So، classify and identify different areas according to their morphologic characteristics is essential. This study attempts to classify different Landform in the southern city of Darab. This research is Descriptive - analysis based on quantitative methods، field and modeling software Where the TPI method were used for the identification and classification of Landforms the study area. The model input data، including slope، curvature width، curvature minimum and maximum curvatures. The results of the study showed that the morphological classification of the study area includes 10 Landform (stream، mid-stream valleys، drainage، high، u-shaped valleys، plains، small، open slopes، steep upper edge high، middle edge of the slope، the high ridge، mountain). Most of Landform in the region of the water courses (32/19 %) and then peaks are (25/36 %).
