  The use of SPOT and Landsat satellite images as combination with field test presents a very useful information on the identification of alluvial fans and their geometry. Existence of very typical alluvial fans belongs to the Plio-Quaternary on the Binalud mountain brow is a very interesting environmental laboratory in which these relationships can be studied and analyzed. This study is done by experimental and laboratory method based on fielddata analysis and interpretation of satellite images. So that identification of fans were done through SPOT and Landsat satellite images along with control of the 1/4000 aerial images of Binalud blocks. For clarification of alluvial fans boundary, ground control operations was carried out in order to their Geomorphometry results have less error. The main purpose of this research is to identify the geomorphometryan quantitative relationships of south Binalud's alluvial fans through reconciliation of round prospectand field observations. Comparison of SPOT and Landsat satellite images in identification of 20 large and small alluvial fans of southern Binaloud mountains forehead revealed that SPOT resolution strength and accuracy of images in geometric reviewing of alluvial fans is higher than Landsat but Landsat satellite images is more applicable in identification of large-scale forms of alluvial fans surfaces.

Keywords: geomorphometry, plio quaternary alluvial fans, alluvial fans quantative relationships and drainage basin, SPOT imagery, south Binalood
